Near-Field Observations and Source Parameters of Central California Earthquakes

Abstract

In 1966-67 the San Andreas Geophysical Observatory (SAGO) was established on the San Andreas fault zone in central California some 5 miles south of Hollister. This study is an investigation of near-field radiation from local earthquakes recorded on broadband seismometer systems at SAGO. From the library of events preserved on magnetic tape, 13 earthquakes were selected with a magnitude range of 2.4 to 5.1, an epicentral distance range of 2 to 40 km, and a variety of apparent source geometries relative to the main throughgoing San Andreas fault trace. The data set samples a range of magnitudes at a given distance for one type of comparison and a range of distances at a given magnitude for another.
