Gerald Mavko
Professor (Research) of Geophysics, Emeritus
Bio
I work to discover and understand the relationship between geophysical measurements and the rock and fluid properties that they sample in the Earth. My students and I have begun to understand the impact of rock type, porosity, pore fluids, temperature, and stress on seismic wave propagation and electromagnetic response. We are also working to quantify the links between geophysical measurements and the sedimentary and diagenetic processes that determine rock mineralogy and texture. Ultimately, this work allows us to better infer, from geophysical images, the composition and physical conditions at depth.

Current Research and Scholarly Interests
Research
I work to discover and understand the relationship between geophysical measurements and the rock and fluid properties that they sample in the Earth. My students and I have begun to understand the impact of rock type, porosity, pore fluids, temperature, and stress on seismic wave propagation and electromagnetic response. We are also working to quantify the links between geophysical measurements and the sedimentary and diagenetic processes that determine rock mineralogy and texture. Ultimately, this work allows us to better infer, from geophysical images, the composition and physical conditions at depth.
Teaching
I teach courses for graduate and undergraduate students on rock physics--the study of the physical properties of rocks and how they can be detected and mapped using seismic and electrical methods. This includes theory, laboratory measurements, and field data analysis. I also lead seminars in which students present and critique their ongoing research in rock physics.

POSTSEISMIC VISCOELASTIC REBOUND
SCIENCE
1974; 183 (4121): 204-206
Abstract
The sudden appearance of a dislocation, representing an earthquake, in an elastic layer (the lithosphere) overriding a viscoelastic half space (the asthenosphere) is followed by time-dependent surface deformation, which is very similar to in situ postseismic deformation. The spectacular postseismic deformation following the large Nankaido earthquake of 1946 yields for the asthenosphere a viscosity of 5 x 10(19) poise and a 50 percent relaxation of the shear modulus. Large thrust type earthquakes may provide, in the future, a new method for exploring the rheology of the earth's upper mantle.
