Exploration Basis
Compare results of dense arrays with less densely spaced instruments
Results from a dense array of passive seismometers are presented. Data collected during the 18-month deployment of 16 dense mini-arrays in the region of the China Lake geothermal field near Ridgecrest, CA was used. The crustal structure within the geothermal field, its relationship to regional tectonic features, and search for an indication of mantle influence on volcanism was imaged. The mini-arrays consist of mostly short period instruments arranged in orthogonal line arrays with 1/2-km station spacing. The average distance between each array is approximately 5 km. It was calculate that there are 375 good quality mini-array beamed receiver functions for teleseismic events.
