Notes
In mid-1989 the authors designed and collected four seismic reflection/refraction profiles that addressed the crustal structure of the Coso geothermal field. The two main east-west and north-south profiles crossed at the southeastern most base of Sugar Loaf Mountain. Both in-line and cross-line Vibroseis and explosion data were recorded on each of these approximately 12-mi lines. This was accomplished with the simultaneous operation of two 1024-channel sign bit recording systems while four medium-weight P-wave vibrators traversed each line and 16 drilled charges were set off. A single recording system was used on each of the other profiles, one of which was a 4-mi-long, 700-channel P-wave profile connecting the Sierran front to the center of Rose Valley, and the other of which was a 2-mi-long, 240-channel SH-wave line runnings slightly southeastward from the junction of the main lines. Rough CMP stacks of the data that included depth varying velocities at 2-mi lateral intervals were completed in the field.
