Carl M Wentworth
Carl, a Scientist Emeritus with the Geology, Minerals, Energy, and Geophysics Science Center, is continuing a varied career that has included geologic mapping, geologic safety of nuclear power reactors, tectonic studies combining geology and geophysics, landslide hazards, and Quaternary stratigraphy and tectonics. He holds Ph.D. and M.S. degrees in Earth Science from Stanford University.
Carl obtained a Ph.D. degree from Stanford University in 1967, having joined the U.S. Geological Survey full time in Menlo Park, CA, in 1963. He retired in 2004 and has continued in emeritus status in the Menlo Park, CA, office since. His work over the past 55 years, mostly in California, has involved geologic mapping; study of landslide, fault and earthquake hazards; management of a national research program on hazards to power reactors; investigation of crustal structure using deep reflection profiling; study of a deep Quaternary basin and its cyclic record of climate variation; and study of the Franciscan Complex and its tectonostratigraphic terranes.
