Abstract:

Preliminary analysis of long-period recordings of five central California earthquakes indicates that the long-period of the observed spectra may be influenced by the recording site that the spectrum for small earthquakes tends to be somewhat peaked and that a Q of 100 seems to be appropriate for the area of interest. Work in Nevada has led to selection of a site for a continuation of the near-field experiment. The area selected is north of the Mina area and south of Fairview Peak. Stations there would be expected to record at least one event per year with M or 4.
