More detailed analysis of microearthquakes over a longer period of time
The permanent 18-station network of three-component digital seismometers at the seismically active Coso geothermal area, California, provides high-quality microearthquake (MEQ) data that are well suited to investigating temporal variations in structure related to processes within the geothermal reservoir. A preliminary study (Julian, et al. 2003; Julian et al. 2004) comparing data from 1996 and 2003 found significant variations in the ratio of the seismic wave-speeds, V p/V s , at shallow depths over this time interval. This report describes results of a more detailed study of each year from 1996 through 2004.
