Book Description
Dynamic Earth presents the principles of convection in the earth's mantle in an accessible style. Mantle convection is the process underlying plate tectonics, volcanic hotspots and, hence, most geological processes. The book summarises key observations and presents the relevant physics starting from basic principles. The main concepts and arguments are presented with minimal mathematics, although more mathematical versions of important aspects are included for those who desire them. The book also surveys geochemical constraints and mantle evolution. The audience for Geoff Davies' book will be the broad range of geologists who desire a better understanding of the earth's internal dynamics, as well as graduate students and researchers working on the many aspects of mantle dynamics and its implications for geological processes. It is also suitable as a text or supplementary text for upper undergraduate and postgraduate courses in geophysics, geochemistry, and tectonics.

Book Description
This volume opens up new perspectives on the physics of the Earth’s interior and planetary bodies for graduate students and researchers working in the fields of geophysics, planetary sciences and geodesy. It looks at our planet in an integrated fashion, linking the physics of its interior to geophysical and geodetic techniques that record, over a broad spectrum of spatial wavelengths and time scales, the ongoing modifications in the shape and gravity field of the planet. Basic issues related to the rheological properties of the Earth and to its slow deformation are considered, in both mathematical and physical terms, within the framework of an analytical relaxation theory. Fundamentals of this theory are developed in the first two Chapters. Chapters 3-9 deal with a wide range of applications, ranging from changes in the Earth’s rotation to post-seismic deformation and from sea-level variations induced by post-glacial rebound to tidal deformation of icy moons of the Solar System. This Second Edition improves substantially our formalism implementing compressibility in viscoelastic relaxation. Chapter 5 now contains new developments in the physics of the gravitational effects of large earthquakes at subduction zones, made possible by new gravity data from space missions. The new Chapter 9 of this Second Edition on deformation and stresses of icy moons enlarges the applications of the book to Planetology, dealing with the additional complications in the theory of viscoelastic relaxation introduced by the shallow low-viscosity zones and inviscid water layers of the moons of Jupiter and Saturn.

Book Description
In their search for solutions to problems concerning the dynamics of the Earth as a self-gravitating body, the authors have applied the fundamentals found in their book “Jacobi Dynamics” (1987, Reidel). First, satellite observations have shown that the Earth does not remain in hydrostatic equilibrium, which forms the physical basis of modern geodynamics. Secondly, satellite data have established a relationship between the planet’s polar moment of inertia and the potential of the Earth’s outer force field, which proves the most basic point of Jacobi dynamics. This allowed the authors to revise their derivation of the classical virial theorem, introducing the concept of a volumetric force and volumetric moment, and so to obtain a generalized virial theorem in the form of Jacobi’s equation. The main dynamical effects are: the kinetic energy of oscillation of the interacting particles, which explains the physical meaning and nature of gravitational forces; separation of shells of a self-gravitating body with respect to its mass density; differences in angular velocities of the shell’s rotation; continuity in variance of the potential of the outer gravitational force field, together with reductions in the envelope of the interacting masses (volumetric center of gravity); the nature of Earth, Moon and satellite precession; the nature and generating mechanism of the planet’s electromagnetic field; the common nature of gravitational and electromagnetic energy, and other related issues. The work is a logical continuation of the book "Jacobi Dynamics" and is intended for researchers, teachers and students engaged in theoretical and experimental research in various branches of astronomy, geophysics, planetology and cosmogony, and for students of celestial, statistical, quantum and relativistic mechanics and hydrodynamics.

It looks at our planet in an integrated fashion, linking the physics of its interior to the geophysical and geodetic techniques that record, over a broad spectrum of spatial wavelengths, the ongoing modifications in the shape and gravity field of the planet. Basic issues related to the rheological properties of the Earth's mantle and to its slow deformation will be understood, in both mathematical and physical terms, within the framework of an analytical normal mode relaxation theory. Fundamentals of this theory are developed in the first, tutorial part. The second part deals with a wide range of applications, ranging from changes in the Earth's rotation to post-seismic deformation and sea-level variations induced by post-glacial rebound. In the study of the physics of the Earth's interior, the book bridges the gap between seismology and geodynamics.

Book Description
We live on a dynamic Earth shaped by both natural processes and the impacts of humans on their environment. It is in our collective interest to observe and understand our planet, and to predict future behavior to the extent possible, in order to effectively manage resources, successfully respond to threats from natural and human-induced environmental change, and capitalize on the opportunities â€" social, economic, security, and more â€" that such knowledge can bring. By continuously monitoring and exploring Earth, developing a deep understanding of its evolving behavior, and characterizing the processes that shape and reshape the environment in which we live, we not only advance knowledge and basic discovery about our planet, but we further develop the foundation upon which benefits to society are built. Thriving on Our Changing Planet presents prioritized science, applications, and observations, along with related strategic and programmatic guidance, to support the U.S. civil space Earth observation program over the coming decade.

Book Description
Those who funded the sciences of geology 150 years ago intuitively saw the Earth as a unified whole. Since that time, the sciences have specialized into physics, chemistry, biology and geology - specialization that has brought advances, but has unfortunately obscured our view of the unique role that life and death play on our planet.

Book Description
Natural disasters bedevil our planet, and each appears to be a unique event. Leading geologist Susan W. Kieffer shows how all disasters are connected. In 2011, there were fourteen natural calamities that each destroyed over a billion dollars’ worth of property in the United States alone. In 2012, Hurricane Sandy ravaged the East Coast and major earthquakes struck in Italy, the Philippines, Iran, and Afghanistan. In the first half of 2013, the awful drumbeat continued—a monster supertornado struck Moore, Oklahoma; a powerful earthquake shook Sichuan, China; a cyclone ravaged Queensland, Australia; massive floods inundated Jakarta, Indonesia; and the largest wildfire ever engulfed a large part of Colorado. Despite these events, we still behave as if natural disasters are outliers. Why else would we continue to build new communities near active volcanoes, on tectonically active faults, on flood plains, and in areas routinely lashed by vicious storms? A famous historian once observed that “civilization exists by geologic consent, subject to change without notice.” In the pages of this unique book, leading geologist Susan W. Kieffer provides a primer on most types of natural disasters: earthquakes, tsunamis, volcanoes, landslides, hurricanes, cyclones, and tornadoes. By taking us behind the scenes of the underlying geology that causes them, she shows why natural disasters are more common than we realize, and that their impact on us will increase as our growing population crowds us into ever more vulnerable areas. Kieffer describes how natural disasters result from “changes in state” in a geologic system, much as when water turns to steam. By understanding what causes these changes of state, we can begin to understand the dynamics of natural disasters. In the book’s concluding chapter, Kieffer outlines how we might better prepare for, and in some cases prevent, future disasters. She also calls for the creation of an organization, something akin to the Centers for Disease Control and Prevention but focused on pending natural disasters.
