For 23 years I worked for the California Division of Mines and Geology (now California
Geological Survey) and 7 years for the U.S. Geological Survey prior to coming to work
for CERI at the University of Memphis. During that period I worked in several areas
of seismology including probabilistic earthquake hazard and risk, strong ground motion
and the effects of site geology, earthquakes and volcanoes, and field seismological
studies of geothermal areas, aftershock sequences, reservoir induced seismicity, and
the earthquake activity potential of faults. My experience with programming and using
computer systems to process, model, and interpret geophysical data is extensive. As
an undergraduate and during my first two years as a graduate student, I worked on
geophysical problems and did field work in the areas of gravity, magnetism, and geodesy.
This map illustrates Deterministic seismic hazard, showing ground motions expected
from a M7.7 earthquake located northwest of Memphis, on a fault coincident with the
southern linear zone of modern seismicity. Motions are accelerations with oscillation
periods of 1 second for the same area shown in the above inset map and include site
