The 1995 Southern California Network Bulletin

Abstract

The Pasadena Office of the U.S. Geological Survey, together with the California Institute of Technology Seismology Laboratory (Caltech Seismo Lab), operates a network of more than 300 remote seismometers in southern California called the Southern California Seismic Network (SCSN). Signals from these sites are telemetered to the central processing site at the Caltech Seismology Laboratory in Pasadena. These signals are continuously monitored by computers that detect and record thousands of earthquakes each year. Phase arrival times for these events are picked by analysts and archived along with digital seismograms. Data acquisition, processing, and archiving is achieved using the CUSP system (Dollar, 1989). These data are used to compile the SCSN Catalog of Earthquakes , a list beginning in 1932 that currently contains more than 282,000 events. This data set is critical to the evaluation of earthquake hazards in California and to the advancement of geoscience as a whole. This article contains...
