Chris Cramer
More....
Dr. Cramer worked for 23 years 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 he 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. He also has extensive experience with programming and using computer systems to process, model, and interpret geophysical data. As an undergraduate and during his first two years as a graduate student, Chris worked on geophysical problems and did field work in the areas of gravity, magnetism, and geodesy.
Deterministic seismic hazard map 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 amplification effects.
