International Year of Planet Earth
The book series is dedicated to the United Nations International Year of Planet Earth. The aim of the Year
is to raise worldwide public and political awareness of the vast (but often under-used) potential of Earth
sciences for improving the quality of life and safeguarding the planet. Geoscientific knowledge can save
lives and protect property if threatened by natural disasters. Such knowledge is also needed to sustainably
satisfy the growing need for Earth’s resources by more people. Earths scientists are ready to contribute to
a safer, healthier and more prosperous society. IYPE aims to develop a new generation of such experts to
find new resources and to develop land more sustainably.

F oreword
The International Year of Planet Earth (IYPE) was established as a means of raising
worldwide public and political awareness of the vast, though frequently under-used,
potential the Earth Sciences possess for improving the quality of life of the peoples
of the world and safeguarding Earth’s rich and diverse environments.
The International Year project was jointly initiated in 2000 by the International
Union of Geological Sciences (IUGS) and the Earth Science Division of the United
Nations Educational, Scientific and Cultural Organisation (UNESCO). IUGS, which
is a Non-Governmental Organisation, and UNESCO, an Inter-Governmental Organi-

sation, already shared a long record of productive cooperation in the natural sciences
and their application to societal problems, including the International Geoscience
Programme (IGCP) now in its fourth decade.
With its main goals of raising public awareness of, and enhancing research in the
Earth sciences on a global scale in both the developed and less-developed countries
of the world, two operational programmes were demanded. In 2002 and 2003, the
Series Editors together with Dr. Ted Nield and Dr. Henk Schalke (all four being core
members of the Management Team at that time) drew up outlines of a Science and
an Outreach Programme. In 2005, following the UN proclamation of 2008 as the
United Nations International Year of Planet Earth, the “Year” grew into a triennium
(2007–2009).
The Outreach Programme, targeting all levels of human society from decision-
makers to the general public, achieved considerable success in the hands of mem-
ber states representing over 80% of the global population. The Science Programme
concentrated on bringing together like-minded scientists from around the world to
advance collaborative science in a number of areas of global concern. A strong
emphasis on enhancing the role of the Earth sciences in building a healthier, safer
and wealthier society was adopted – as declared in the Year’s logo strap-line “Earth
Sciences for Society”.
The organisational approach adopted by the Science Programme involved recog-
nition of ten global themes that embrace a broad range of problems of widespread
national and international concern, as follows.
• Human health: this theme involves improving understanding of the processes by
which geological materials affect human health as a means of identifying and
reducing a range of pathological effects.
• Climate: particularly emphasises improved detail and understanding of the non-
human factor in climate change.
v
vi Foreword
• Groundwater: considers the occurrence, quantity and quality of this vital resource

for all living things against a background that includes potential political tension
between competing neighbour-nations.
• Ocean: aims to improve understanding of the processes and environment of the
ocean floors with relevance to the history of planet Earth and the potential for
improved understanding of life and resources.
• Soils: this thin “skin” on Earth’s surface is the vital source of nutrients that sustain
life on the world’s landmasses, but this living skin is vulnerable to degradation if
not used wisely. This theme emphasizes greater use of soil science information in
the selection, use and ensuring sustainability of agricultural soils so as to enhance
production and diminish soil loss.
• Deep Earth: in view of the fundamental importance of deep the Earth in supplying
basic needs, including mitigating the impact of certain natural hazards and control-
ling environmental degradation, this theme concentrates on developing scientific
models that assist in the reconstruction of past processes and the forecasting of
future processes that take place in the solid Earth.
• Megacities: this theme is concerned with means of building safer structures and
expanding urban areas, including utilization of subsurface space.
• Geohazards: aims to reduce the risks posed to human communities by both natural
and human-induced hazards using current knowledge and new information derived
from research.
• Resources: involves advancing our knowledge of Earth’s natural resources and
their sustainable extraction.
• Earth and Life: it is over two and half billion years since the first effects of
life began to affect Earth’s atmosphere, oceans and landmasses. Earth’s biolog-
ical “cloak”, known as the biosphere, makes our planet unique but it needs to
be better known and protected. This theme aims to advance understanding of
the dynamic processes of t he biosphere and to use that understanding to help
keep this global life-support system in good health for the benefit of all living
things.
The first task of the leading Earth scientists appointed as Theme Leaders was

the production of a set of theme brochures. Some 3500 of these were published,
initially in English only but later translated into Portuguese, Chinese, Hungarian,
Vietnamese, Italian, Spanish, Turkish, Lithuanian, Polish, Arabic, Japanese and
Greek. Most of these were published in hard copy and all are listed on the IYPE
website.
It is fitting that, as the International Year’s triennium terminates at the end of 2009,
the more than 100 scientists who participated in the ten science themes should bring
together the results of their wide ranging international deliberations in a series of
state-of-the-art volumes that will stand as a legacy of the International Year of Planet
Earth. The book series was a direct result of interaction between the International
Year and the Springer Verlag Company, a partnership which was formalised in 2008
during the acme of the triennium.
This IYPE-Springer book series contains the latest thinking on the chosen themes
by a large number of Earth science professionals from around the world. The books
are written at the advanced level demanded by a potential readership consisting
of Earth science professionals and students. Thus, the series is a legacy of the
Science Programme, but it is also a counterweight to the Earth science information in
Foreword vii
several media formats already delivered by the numerous National Committees of the
International Year in their pursuit of world-wide popularization under the Outreach
Programme.
The discerning reader will recognise that the books in this series provide not only a
comprehensive account of the individual themes but also share much common ground
that makes the series greater than the sum of the individual volumes. It is to be hoped
that the scientific perspective t hus provided will enhance the reader’s appreciation of
the nature and scale of Earth science as well as the guidance it can offer to govern-
ments, decision-makers and others seeking solutions to national and global problems,
thereby improving everyday life for present and future residents of Planet Earth.

International Year of Planet Earth International Year of Planet Earth
Preface
This book series is one of the many important results of the International Year
of Planet Earth (IYPE), a joint initiative of UNESCO and the International Union
of Geological Sciences (IUGS), launched with the aim of ensuring greater and
more effective use by society of the knowledge and skills provided by the Earth
Sciences.
It was originally intended that the IYPE would run from the beginning of 2007
until the end of 2009, with the core year of the triennium (2008) being proclaimed
as a UN Year by the United Nations General Assembly. During all three years,
a series of activities included in the IYPE’s science and outreach programmes
had a strong mobilizing effect around the globe, not only among Earth Scien-
tists but also within the general public and, especially, among children and young
people.
The Outreach Programme has served to enhance cooperation among earth sci-
entists, administrators, politicians and civil society and to generate public aware-
ness of the wide ranging importance of the geosciences for human life and pros-
perity. It has also helped to develop a better understanding of Planet Earth and the
importance of this knowledge in the building of a safer, healthier and wealthier
society.
The Scientific Programme, focused upon ten themes of relevance to society, has
successfully raised geoscientists’ awareness of the need to develop further the interna-
tional coordination of their activities. The Programme has also led to some important
updating of the main challenges the geosciences are, and will be confronting within
an agenda closely focused on societal benefit.
An important outcome of the work of the IYPE’s scientific themes includes
this thematic book as one of the volumes making up the IYPE-Springer Series,
which was designed to provide an important element of the legacy of the Inter-
national Year of Planet Earth. Many prestigious scientists, drawn from different
disciplines and with a wide range of nationalities, are warmly thanked for their

contributions to a series of books that epitomize the most advanced, up-to-date
and useful information on evolution and life, water resources, soils, changing cli-
mate, deep earth, oceans, non-renewable resources, earth and health, natural hazards,
megacities.
This legacy opens a bridge to the future. It is published in the hope that the core
message and the concerted actions of the International Year of Planet Earth through-
out the triennium will continue and, ultimately, go some way towards helping to
establish an improved equilibrium between human society and its home planet. As

Introduction
In the context of the International Year of Planeth Earth (IYPE), the International
Lithosphere Programme (ILP) has taken the responsibility for the scientific coordina-
tion of the IYPE theme Deep Earth.
In the preparatory phase of the IYPE, ILP has organized in June 2007 a meeting
on New Frontiers in Integrated Solid Earth Sciences at the GeoForschungsZentrum
Potsdam to review breakthroughs and challenges in the connection of Deep Earth and
surface processes. The present volume is an outcome of this conference, providing
examples of recent exciting developments in this field as well as an inventory of
opportunities for future research.
The Potsdam conference was held in conjunction with the retirement of Rolf
Emmermann, founding director of GFZ, one of the largest Integrated Earth Research
Institutes of the world. He has also been vital in the realization of major Integrated
Earth Research initiatives such as the International Continental Drilling Programme

(ICDP), succeeding the first big science research project in continental geosciences
in Germany drilling to 9000 m depth (KTB).
Peter Ziegler, well known for his life time activities connecting the energy industry
and in-depth understanding of lithosphere evolution in space and time, is another pio-
neer in the domain of Integrated Solid Earth Science. His fundamental contributions
to the study of the lithosphere are documented in a monumental series of atlases on
the paleogeography of Europe and the North Atlantic as well as in seminal highly
cited papers on sedimentary basins and lithosphere evolution. His 80th birthday in
2008 coincides with the IYPE.
ILP wishes to thank Rolf and Peter for laying the foundations both in terms of
promoting scientific innovation, novel concepts and vision, on which future endeavors
to move the frontiers in Integrated Solid Earth Sciences can build. This volume is
dedicated to both of them.

Abstract During the last decades the Earth sci-
ences are rapidly changing from largely descriptive
to process-oriented disciplines that aim at quantita-
tive models for the reconstruction and forecasting
of the complex processes in the solid Earth. This
includes prediction in the sense of f orecasting the
future behaviour of geologic systems, but also the pre-
diction of geologic patterns that exist now in the sub-
surface as frozen evidence of the past. Both ways of
prediction are highly relevant for the basic needs of
humanity: supply of water and resources, protection
against natural hazards and control on the environmen-
tal degradation of the Earth.
Intensive utilization of the human habitat carries
largely unknown risks of and makes us increasingly
vulnerable. Human use of the outermost solid Earth
intensifies at a rapid pace. There i s an urgent need for
scientifically advanced “geo-prediction systems” that
can accurately locate subsurface resources and forecast
timing and magnitude of earthquakes, volcanic erup-
tions and land subsidence (some of those being man
induced). The design of such systems i s a major mul-
tidisciplinary scientific challenge. Prediction of solid-

Earth processes also provides important constraints for
predictions in oceanographic and atmospheric sciences
and climate variability.
The quantitative understanding of the Earth has
made significant progress in the last few decades.
Important ingredients in this process have been the
advances made in seismological methods to obtain

information on the 3D structure of the mantle and the
lithosphere, in the quantitative understanding of the
lithospheric scale processes as well as the recogni-
tion of the key role of quantitative sedimentary basin
analysis in connecting temporal and spatial evolution
of the system Earth recorded in their sedimentary fill.
Similar breakthroughs have been made in the spa-
tial resolution of the structural controls on lithosphere
and (de)formation processes and its architecture by
3D seismic imaging. Earth-oriented space research is
increasingly directed towards obtaining a higher reso-
lution in monitoring vertical motions at the Earth’s sur-
face. Modelling of dynamic topography and landform
evolution is reaching the phase where a full coupling
can be made with studies of sediment supply and ero-
sion in the sedimentary basins for different spatial and
temporal scales.
Quantitative understanding of the transfer of mass
at the surface by erosion and deposition as well as

their feed back with crustal and subcrustal dynam-
ics presents a new frontier in modern Earth sciences.
This research bridges current approaches separately
addressing high resolution time scales for a limited
near surface record and the long term and large scale
approaches characteristic so far for the lithosphere and
basin-wide studies. The essential step towards a 4D
approach (in s pace and time) is a direct response to
the need for a full incorporation of geological and geo-
physical constraints, provided by both the quality of
modern seismic imaging as well as the need to incor-
porate smaller scales in the modelling of solid Earth
processes.

Introduction
The structure and processes of the deep Earth may
sound remote from everyday concerns, but both have
strong relevance for humanity’s basic needs, such as
supply of water and resources, protection against natu-
ral hazards, and control of the environmental degrada-
tion of the Earth.
In recent years geologists have come to understand
the solid Earth in more measurable (“quantitative”)
ways. Better seismic techniques have brought us to a

better understanding of the 3D structure of the Earth’s
mantle and lithosphere. We can describe, in numeri-
cal terms, how the deep Earth system works; at the
same time, quantitative analysis of the basins in which
sediments accumulate has allowed us to connect the
deep Earth system with the record of those changes
written in the sediments that build up over geological
time.
Better ways of “seeing” through solid rock have
allowed Earth scientists to understand the fine structure
of the Earth’s outer shell, or “lithosphere”, and how
it deforms under pressure from the movement of the
crustal plates, in three dimensions. Recent advances in
the ways geologists can give things accurate ages in
years have made it possible to find out how fast tec-
tonic and surface processes take place, with the pre-
cision necessary to distinguish between the different
forces that shape the landscape.
Using space satellites to survey the Earth has
allowed us to obtain ever-higher resolution when mon-
itoring the vertical motions of Earth’s surface. Mod-
elling the way topography changes with time has now
reached the stage where it is possible to couple stud-
ies of sediment supply and erosion in time and space.
At a much smaller scale, we face problems of sedi-
mentary architecture (the way different sediments are
structured), and of imaging this architecture using
remote sensing techniques that use seismic or elec-
tromagnetic waves to see inside them, like a “body
scanner”.

Despite enormous progress in the last 15 years,
such remote imaging barely keeps pace with the great
demands society places upon it, with urgent needs for
water supplies, mineral resources, protection against
natural hazards and control of the environment.
Below we highlight some key issues central in mod-
ern integrated solid Earth science.
Mass Transfer
“Mass transfer” means the way in which rocks are
eroded from certain areas of the Earth’s crust and
redeposited in others, and the way the Earth’s interior
responds to those gradual changes in pressure. This
presents a new frontier in modern Earth sciences –
namely, trying to understand these processes quanti-
tatively.
This needs a research strategy bridging current
approaches that separately address high-resolution
timescales for a limited near-surface record on the one
hand, and the long-term and large-scale approaches
that are more typical of studies at the scale of whole
sedimentary basins. The essential step towards a four
dimensional (4D) approach (i.e., involving both space
and time) requires modelling solid Earth processes in
a way that incorporates smaller scale data with high
quality modern seismic imaging. We need to probe
the deep Earth, to obtain a high-resolution image of
both deep Earth structure and processes, if we are to
quantify and constrain the forces that drive the Earth’s
crustal plates.
The deep Earth framework provides a unifying

theme capable of addressing, in a process-oriented
way, the full dynamics of the Earth system. Recent
technical advances (including seismic tomography,
Earth-oriented space observations, oceanic and conti-
nental drilling, modelling, and analytical techniques)
have created fertile ground for a breakthrough by
means of a global effort that integrates state-of-
the-art methodology and the assembly of global
databases.
Continental Topography: Interplay of
Deep Earth and Surface Processes
Topography, the landscape’s physical shape, is a prod-
uct of the interaction between processes taking place
deep in the Earth, on its surface, and in the atmosphere
above it. Topography influences society, not only in
terms of the slow process of landscape change, but also
through climate. Topographic evolution (changes in
land, water and sea levels) can seriously affect human
life, as well as plants and animals. When levels of
fresh water or of the sea rise, or when land subsides,
the risk of flooding increases, directly affecting local
Perpectives on Integrated Solid Earth Sciences 3
ecosystems and human settlements. On the other hand,
declining water levels and uplift may lead to a higher
risk of erosion and even desertification.
These changes are caused both by natural processes
and human activities, yet the absolute and relative con-
tributions of each are still little understood. The present
state and behaviour of the Shallow Earth System is
a consequence of processes on a wide range of time

scales. These include:
• long-term tectonic effects on uplift, subsidence and
river systems;
• residual effects of ice ages on crustal movement (the
weight of ice accumulations depresses the crust, and
takes tens of thousands of years to recover following
melting of the ice sheet;
• natural climate and environmental changes over the
last millennia right up to the present;
• powerful anthropogenic impacts;
If we are to understand the present state of the Earth
System, to predict its future and to engineer our sus-
tainable use of it, this spectrum of processes (operating
concurrently but on different time scales) needs to be
better understood. The challenge to Earth science is to
describe the state of the system, to monitor its changes,
to forecast its evolution and, in collaboration with oth-
ers, to evaluate different models for its sustainable use
by human beings. Research will need to focus upon the
interplay between active tectonics, topographic evolu-
tion, and related sea level changes and drainage pattern
(river) development. This includes developing an inte-
grated strategy for observation and analysis, empha-
sising large scale changes in vulnerable parts of the
globe.
Making accurate geological predictions in com-
plexly folded and faulted mountain belts will require
collaboration between researchers from several broad
fields of expertise. Among other scientific disciplines,
geology, geophysics, geodesy, hydrology and climatol-

ogy, as well as various fields of geotechnology, will
need to be integrated.
Geoprediction: Observation,
Reconstruction and Process Modelling
The increasing pressure that we are placing upon the
environment makes us increasingly vulnerable. We
have an urgent need for scientifically advanced “geo-
prediction systems” that can accurately locate sub-
surface resources and forecast the timing and magni-
tude of earthquakes, volcanic eruptions and land sub-
sidence (some of which is caused by human activity).
The design of such systems poses a major multidisci-
plinary scientific challenge. Prediction of solid Earth
processes also imposes important constraints on pre-
dictions in oceanographic and atmospheric sciences,
including climate variability.
Predicting the behaviour of geological systems
requires two things: a thorough understanding of the
processes, and high quality data. The biggest progress
in quantitative prediction is expected to occur at the
interface between modelling and observation. This is
the place where scientific hypothesis is confronted with
observed r eality. In its most advanced version, the
integrated sequence “observation, modelling, process
quantification, optimization and prediction” is repeat-
edly carried out (in time and space) and the outcome
is vital in generating fundamentally new conceptual
developments.
Observing the Present
Information on the (present-day) structure of the sub-

surface and the deeper interior of the Earth (at var-
ious scales) is a key aspect of solid Earth science.
This pertains to the study of both active processes and
those that have ceased to be active but which may
have contributed to present-day structures. The study
of active processes plays an important role in this
respect because process-related observations (concern-
ing, for example, earthquake activity, surface defor-
mation and the Earth’s gravity field) can be made
(and used) as constraints upon process models. The
process-related insight gained from such exercises is
very valuable in guiding our reconstruction of past
processes.
Reconstructing the Past
Although the solid Earth has changed continuously
through time, it still retains vestiges of its earlier evo-
lution. Revealing the roles played in controlling rates
of erosion and sedimentation by internal lithospheric
4 S.A.P.L. Cloetingh and J.F.W. Negendank
processes and external forcing represents a major
challenge.
The sedimentary cover of the lithosphere provides
a high-resolution record of the changing environment,
as well as of deformation and mass transfer at the sur-
face and at different depths in the crust, lithosphere,
and mantle system. In the last few years, pioneer-
ing contributions have helped to explain how litho-
sphere tectonic processes and the sedimentary record
are related. These demonstrate, for example, the con-
trol exerted by stress fields in the lithospheric plates

on the sequences of sediments that accumulate above
them, and on the record of relative sea-level changes
in sedimentary basins. Earth scientists are also becom-
ing increasingly conscious of the way that active tec-
tonic processes affect sedimentary basins, as well
as the major implications these processes have for
fluid flow and recent vertical motions in the cou-
pled system that links the deep Earth and its surface
processes.
The sedimentary cover of the lithosphere provides a
record of the changing environment, involving defor-
mation and mass transfer at the Earth’s surface and at
different depths within the crust, lithosphere, and man-
tle system. In the past few decades, sedimentary basin
analysis has been in the forefront in integrating sedi-
mentary and lithosphere components of the (previously
separate) fields of geology and geophysics. Integrat-
ing active tectonics, surface processes and lithospheric
dynamics in the reconstruction of the ancient topog-
raphy of these basins and their surrounding areas is a
key objective. A fully integrated approach (combining
dynamic topography and sedimentary basin dynam-
ics) is also important, considering the key societal role
these basins play as resource locations, such as hydro-
carbon reservoirs and source rocks. Moreover, given
that most people alive today live either within or close
to sedimentary basins (in coastal zones and deltas)
both populations and their s ettlements remain vul-
nerable to geological hazards posed by Earth system
activity.

Lithosphere Deformation Behaviour
The way the rocks of the mantle flow exerts con-
trols on the thickness and strength of the lithospheric
plates, the extent of coupling between plate motions
and flow in the Earth’s interior, and the pattern and
rate of convection in the asthenosphere – as well as
more local processes such as the pattern and rate of
mantle flow and melt extraction at mid-ocean ridges.
In order to understand the dynamic behaviour of the
outer parts of the solid Earth, notably the dynamics of
lithospheric extension and associated rifting and sed-
imentary basin development, a detailed knowledge of
the way in which the different zones of the mantle flow
is essential.
Process Modelling and Validation
Modelling solid Earth processes is in a transitional
stage between kinematic and dynamic modelling. This
development cannot take place without the interaction
with (sub)disciplines addressing Earth structure and
kinematics, or reconstructions of geological processes.
In fact, advances in structure related research, in par-
ticular the advent of 3D seismic velocity models, have
set the stage for studies of dynamic processes inside
the Earth. Structural information is a prerequisite for
modelling solid Earth processes. Similarly, informa-
tion on present-day horizontal and vertical movements,
as well as reconstructed past motion, temperatures or
other process characteristics, is used in formulating
and testing hypotheses concerning dynamic processes.
Inversely, the results of process modelling motivate

and guide research in observation of the present and
reconstruction of the past.
Through the emphasis on process dynamics, it is in
process modelling in particular that the full benefits
of coupling spatial and temporal scales become appar-
ent. The scale of the processes studied ranges from the
planetary dimension to the small scale relevant to sedi-
mentary processes, with the depth scale being reduced
accordingly.
Challenges and New Developments
In spite of the great successes of plate tectonic the-
ory in modern Earth science, fundamental questions
still remain concerning the evolution of continents and
their role in the dynamics of the Earth’s lithosphere
and mantle. The growth process of continents (on the
Perpectives on Integrated Solid Earth Sciences 5
scale of a differentiating planet), their thickness and
the dynamic coupling with the underlying mantle are
topics requiring focused attention from a series of
sub-disciplines.
Equally important questions remain to be solved
concerning mechanisms controlling continental tecton-
ics and their effects on vertical movements, dynamic
topography, and sedimentary basin formation. Vital in
this respect are the dynamics of splitting continents,
how one plate dives beneath another at a subduction
zone, how mountains are built and denuded by erosion,
and their effects on continental platform evolution and
on the boundary processes between oceans and con-
tinents. Equally important are the rates and scales at

which these processes operate.
In order to quantify the key processes involved in
solid Earth science, it is essential to couple both inter-
nal and external forcing. From the extensive scale
of (upper) mantle and lithospheric structure and pro-
cesses, work on crustal structure and processes, the
dynamics of topography and sedimentary basins and
their s ediment fills progresses at increasingly finer
scales.
Integrated Approach to Selected Natural
Laboratories and Analogues
Analogues are the key to reconstructing the past and
predicting the future in the geological sciences. The
natural laboratory that is the Earth allows us to observe
different time slices at a range of scales, which, on their
own, offer only an incomplete record of 4 billion years
of its history.
Major large-scale integrated deep and surface Earth
initiatives are already under development, covering
Europe (TOPO-EUROPE, EUROARRAY, EPOS), the
USA (EARTHSCOPE), the African Plate, and the
South-American Plate. At the same time, major inter-
national research initiatives such as the Integrated
Ocean Drilling Programme (IODP), the International
Continental Drilling Programme (ICDP), and the Inter-
national Lithosphere Programme (ILP) provide a plat-
form from which to extend these research efforts into
other areas of the globe. The complementary strength
of research methods focused on selected natural labo-
ratories will lead to a multi-method approach unparal-

leled so far.
Coupled Deep Earth and Surface
Processes
The modern Earth system approach requires a com-
prehensive integration of existing databases, with the
capacity to expand to allow for storage and exchange of
new data collected. Unification and coupling of exist-
ing modelling techniques is needed to achieve full
integration of what are currently discipline-oriented
approaches and to expand fully “next generation” 3D
applications. Furthermore, flexible exchange for “feed-
back loops” in the quantification of processes is needed
at the interface between databases and modelling tools.
Consequently, major investments in Information Tech-
nology are called for so as to expand existing computer
hardware and software facilities.
Coupled Process Modelling and Validation
Process modelling and validation allows full imple-
mentation and optimization of the quantitative
approach pursued in programmes such as TOPO-
EUROPE. In this context, two interrelated aspects
should be emphasised. The first is the fundamental
capacity of numerical process modelling to link the
geometrical/structural, mechanical properties, and
kinematic and dynamic aspects (and data) of the
processes studied. Second, using this capacity, quan-
titative modelling and reliable constraints on fluxes
and timing obtained by state-of-the-art analytical
tools will play a crucial role in research (and the
guiding of research) aimed at deciphering complex

interactions between spatial and temporal scales in
Earth processes.
ILP Activities Within the International
Year of Planet Ear th
ILP Activities within the IYPE are centred within the
following eight themes:
• “Earth accretionary systems (in space and time)”
(ERAS) (chairs: Peter Cawood, Alfred Kröner)
6 S.A.P.L. Cloetingh and J.F.W. Negendank
The initiation and development of accretionary oro-
gens forms the central aim of this integrated, multi-
disciplinary program.
• “New tectonic causes of volcano failure and pos-
sible premonitory signals” (chairs: Alessandro
Tibaldi, Alfredo F.M. Lagmay, Vera Ponomareva,
Theofilos Toulkeridis)
More than 500 million people live in hazardous
zones adjacent to active volcanoes all over the world
and volcano slope instability represents one of the
most extreme hazards.
• “Lithosphere-asthenosphere Interactions” (chairs:
Andrea Tommasi, Michael Kendall, Carlos
J. Garrido)
This project focuses on the interaction between the
lithosphere, the outer shell on which we live, and
the asthenosphere and/or deep mantle. The dynamic
processes of the Earth’s interior affect our day to-
day life in a profound way.
• “Ultra-deep continental crust subduction”
(UDCCS) (chairs: Larissa Dobrzhinetskaya,

Patrick O’Brien, Yong-Fei Zheng)
Ultra-high-pressure metamorphic (UHPM) geology
is a new discipline that came into being after
discoveries of coesite and microdiamond within
rocks of continental affinities involved in colli-
sional orogenic belts. UHPM terranes and UHP
minerals and rocks present a “special natural
laboratory.”
• “Global and regional parameters of paleoseis-
mology; implications for fault scaling and future
earthquake hazard” (chair: Paolo Marco De
Martini)
This project aims to support and promote the study
of the main paleoseismological parameters at a
global and regional scale to develop new ideas on
fault scaling relationships and modern earthquake
hazard estimates.
• “Sedimentary basins” (chairs: François Roure,
Magdalena Scheck-Wenderoth)
Sedimentary basins provide mankind’s largest
reservoir for Earth energy and natural resources.
As recorder of tectonics and climate interaction
they enable to reconstruct the history of the
continents.
• “Temporal and spatial change of stress and strain”
(chair: Oliver Heidbach)
This project aims to identify, analyse and inter-
pret variations of crustal stress and strain pat-
terns at diverse tectonic settings characterized by
return periods for strong earthquakes in the order

of 50–1,000 years.
• “Baby plumes – origin, characteristics, lithosphere-
asthenosphere interaction and surface expression.”
(chair: Ulrich Achauer)
The project focuses on interdisciplinary studies of
baby-plumes to steer the debate on the origin and
nature of plumes in general, addressing their geody-
namic implications.
Research on these themes is accompanied by
three coordinated efforts of a more regional nature
and a global research initiative. Two of these
projects (TOPO-EUROPE: 4D Topography Evolu-
tion in Europe: Uplift, Subsidence and Sea Level
Rise [chair: Sierd Cloetingh] and TOPO-CENTRAL-
ASIA: 4D Topographic Evolution in Central Asia:
Lithosphere Dynamics and Environmental Changes
since Mesozoic [chairs: Qingchen Wang, Shigenori
Maruyama, Boris Natal’in, Yan Chen]) address topog-
raphy evolution in space and time, adopting Europe
and Central Asia as natural laboratories.
DynaQlim (Upper Mantle Dynamics and Quater-
nary Climate in Cratonic Areas [chair: Markku Pouta-
nen]) has its focus on the study of the relations between
upper mantle dynamics, its composition and physical
properties, temperature, rheology, and Quaternary cli-
mate. Its regional focus lies on the cratonic areas of
northern Canada and Scandinavia.
The International Continental Scientific Drilling
Program (ICDP) [Executive Committee: Rolf Emmer-
mann, Ulrich Harms et al.] coordinates conti-

nental scientific drilling efforts with research top-
ics of high international priority. Main objectives
addressed in ICDP include geodynamics and natu-
ral hazards, volcanic systems and thermal regimes,
Earth’s history and climate, impact structures and
mass extinctions as well as deep biosphere and gas
hydrates (see also for further
information).
The above themes are addressed by a number of
ILP Task Forces and Regional Coordinating Commit-
tees. Below we give an overview of their research
activities.
Perpectives on Integrated Solid Earth Sciences 7
Task Force 1: Earth Accretionary Systems
(in Space and Time) (ERAS)
Classic models of orogens involve a Wilson cycle of
ocean opening and closing with orogenesis related
to continent-continent collision (Dewey, 1969; Wil-
son, 1966). Such models fail to explain the geo-
logical history of a significant number of orogenic
belts throughout the world in which deformation,
metamorphism and crustal growth took place in an
environment of ongoing plate convergence. These
belts are termed accretionary orogens but have also
been referred to as non-collisional or exterior oro-
gens, Cordilleran-, Pacific-, Miyashiro-, and Turkic-
type orogens (Matsuda and Uyeda, 1971; Windley,
1992; ¸Sengör, 1993; Maruyama, 1997; Ernst, 2005).
Accretionary orogens form at sites of subduction
of oceanic lithosphere. They consist of accretionary

wedges (Fig. 1) containing material accreted from the
downgoing plate and eroded from the upper plate,
island arcs, ophiolites, oceanic plateaus, old continen-
tal blocks, post-accretion granitic rocks and metamor-
phic products up to the granulite-facies, exhumed high-
pressure metamorphic rocks, and clastic sedimentary
basins (Cawood et al., 2009). Accretionary orogens
appear to have been active throughout much of Earth
history and constitute major sites of continental growth
(Cawood et al., 2006). They contain significant mineral
deposits (Groves and Bierlein, 2007) and thus provide
the mineralisation potential of many countries such as
Australia, Canada, Zimbabwe, Saudi Arabia, Yemen,
Nigeria, China, Kazakhstan and Mongolia.
Understanding of the processes for the initiation and
development of accretionary orogens is moderately
well established in modern orogens such as Japan,
Indonesia and Alaska, the broad structure and evo-
lution of which are constrained by seismic profiles,
tomography, field mapping, palaeontology, i sotope
geochemistry and geochronology. However, the pro-
cesses responsible for the cratonization and incorpo-
ration of accretionary orogens into continental nuclei
(Cawood and Buchan, 2007) and the mechanisms of
formation of pre-Mesozoic accretionary orogens are
poorly understood. In a uniformitarian sense many of
the features and processes of formation of modern
accretionary orogens have been little applied to pre-
Mesozoic orogens. Resolution and understanding of
these processes form the central aim of this Task Force.

This integrated, multi-disciplinary and comprehen-
sive program in selected accretionary orogens will
provide a common framework to better understand
their development. The detailed work program of Task
Force ERAS (EaRth Accretionary Systems in space and
time) will be further developed and refined through
meetings and international conferences. These will
encourage interested scientists to join in developing
plans to implement components of the program, to

advance our understanding of accretionary systems in
particular and continental evolution in general. The
Task Force brings together scientists from many disci-
plines of the Earth sciences as evidenced by a volume
on “Accretionary systems in space and time” (Cawood
et al., 2009) with 14 contributions covering aspects
of accretionary processes from the Archaean to the
Cenozoic.
Task Force 2: Tectonic Causes of Volcano
Failure and Possible Premonitory Signals
“Tectonic causes of volcano failure and possible pre-
monitory signals” is an active component of the ILP
theme “Geoscience of global change”. It is aimed at

developing a better understanding of how volcanoes
work with special emphasis on the control exerted
by regional tectonics on volcano evolution. Specific
objectives comprise a better understanding of the
magma feeding systems, deformations in volcanoes
and volcanic regions, and how these interact with haz-
ard phenomena like lateral collapses of volcanic edi-
fices (Tibaldi et al., 2008a). The conceptual framework
is developed through an interdisciplinary study of sev-
eral key sites distributed around the world that, taken
together, provide insights on real volcanic systems
belonging to different geodynamic settings (Tibaldi
and Lagmay, 2006). These comprise the Philippines
volcanic arc, the Andes of Ecuador, Chile, Bolivia
and Argentina, the Mediterranean zone, Iceland and
Kamchatka. During 2008–2009, several studies have
also been carried out on deeply eroded volcanoes in
order to identify the inner magma feeding system as
analogues to modern volcanoes. These studied eroded
volcanoes are located in Ireland, Great Britain, Iceland,
France, Italy and USA. Applied methodologies mainly
comprise structural geology, stratigraphy, petrography,
geochemistry, geotechnics, engineering geology, and
geophysics. These data are crosscut with numerical
and analogue modelling.
Most of the involved researchers operate in coun-
tries where threats from active volcanoes and tectonic
earthquakes are widespread (e.g., Eichelberger et al.,
2007; Calvari et al., 2008). This means that the results
of this project are useful in different nations at the same

time and represent a valuable data source for scientists
and administrative and government panels. It should
be emphasised that several selected volcanoes, such
as Mayon, Cotopaxi, Mt Etna, and Stromboli (Fig. 2),
represent major hazards in terms of loss of life and eco-
nomic damage.
The studies carried out in these areas allowed to gain
insights into the mode of magma emplacement through
the upper crust and in the interior of volcanoes, as
well as to better understand how volcano slopes deform
under the magma-tectonic stress field. Major work in
fact has been devoted to understand the coupling of the
local stresses induced by magmatic and gravity forces
with the remote stresses transmitted by regional tecton-
ics (Fig. 3). At the same time, efforts have been devoted
to find out the causes of the so called “super erup-
tions” and their consequences (Self and Blake, 2008),
whose triggering factors can comprise wide failure of
volcanoes.
Physical scaled modelling has also been carried out
in order to simulate deformations in volcanoes lying
above reverse faults with different geometries. The
