To analyze attenuation and source properties
A multiple-empirical Green's function method was used to determine source properties of small (M −0.4 to 1.3) earthquakes and P-wave and S-wave attenuation at the Coso Geothermal Field. Source properties of a previously identified set of clustered events from the Coso geothermal region are first analyzed using an empirical Green's function (EGF) method. Stress-drop values of at least 0.5-1 MPa are inferred for all of the events. The inferred attenuation variability corresponds to the heat-flow variations within the geothermal region. A central low-Q region corresponds well with the central high-heat flow region. Also an additional detailed structure was also suggested.
