These data\ \ show the details of aseismic fault failure, preseismic, coseismic and postseismic\ \ deformation, earthquake nucleation, volcanic deformation and volcanic processes.\ \ Theoretical modeling of these processes suggests testable physical explanations\ \ in term of physics of failure, the role of fluids in the crust, strain redistribution,\ \ and likely properties of fault zone materials. Very near-field data on slow\ \ slip, earthquakes and dynamic rupture were obtained in fault zones at 3.6\ \ km depth in South Africa, a few 10\u2019s of meters from earthquakes from\ \ M=-4.5 to M=2." professional_experience: - Research Geophysicist Emeritus - U.S. Geological Survey - '1970-1972: Assistant Professor, Dept.
