Exploration Basis
Locate an active fault zone by analyzing seismic guided waves from microearthquake data
An active fault zone was located in the Coso geothermal field, California, by identifying and analyzing a fault-zone trapped Rayleigh-type guided wave from microearthquake data. The wavelet transform is employed to characterize guided-wave's velocity-frequency dispersion, and numerical methods are used to simulate the guided-wave propagation. The modeling calculation suggests that the fault zone is approximately 200m wide, and has a P wave velocity of 4.80 km/s and a S wave velocity of 3.00 km/s
