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.

ALACARTE offers a convenient way to compile geologic maps in the computer as spatial databases that can be used to prepare both cartographic images and analytic derivatives. It is a menu-controlled shell, organized in geologic terms, that provides on-screen control of the program ARC/INFO, a commercial geographic information system (GIS). Input can be from imported scans, digitizer tracing, or on-AuthorsCarl M. Wentworth, Todd T. FitzgibbonALACARTE User Interface - AML Code and Demonstration Maps

No abstract available.AuthorsRobert W. Simpson, R.C. Jachens, Carl M. WentworthThe style of late Cenozoic deformation at the eastern front of the California Coast Ranges
The 1983 Coalinga earthquake occurred at the eastern boundary of the California Coast Ranges in response to northeast directed thrusting. Such movements over the past 2 Ma have produced Coalinga anticline by folding above the blind eastern tip of the Coalinga thrust zone. The 600-km length of the Coast Ranges boundary shares a common structural setting that involves westward upturn of Cenozoic andAuthorsC. M.

Since 1973, the U.S. Geological Survey (USGS), with support from the Nuclear Regulatory Commission, has conducted extensive investigations of the tectonic and seismic history of the Charleston, S.C., earthquake zone and surrounding areas. The goal of these investigations has been to discover the cause of the large intraplate Charleston earthquake of 1886, which dominates the record of seismicity iAuthorsDavid Gottfried, C. S.
