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.
