Exploration Activity: Micro-Earthquake At Coso Geothermal Area (1987)

Exploration Activity Details
Location Coso Geothermal Area
Exploration Technique Micro-Earthquake
Activity Date 1987

Usefulness not indicated
DOE-funding Unknown

Exploration Basis
Analysis was done to link the zones of decreased P velocity to contemporary magmatic activity
Inversion of 4036 P wave travel time residuals from 429 local earthquakes using a tomographic scheme provides information about 3D upper crustal velocity variations in the Indian Wells Valley-Coso region of southeastern CA. The residuals are calculated relative to a Coso-specific velocity model, corrected for station elevation, weighted, and back-projected along their ray paths through models defined with layers of blocks.
