|Exploration Activity Details|
|Location||North Brawley Geothermal Area|
|Exploration Technique||Refraction Survey|
|Activity Date||1979 - 1979|
|Usefulness||useful regional reconnaissance|
The purpose of this extensive study was to generate a more accurate velocity model and structural understanding of Imperial Valley.
An extensive seismic refraction study was done through Imperial Valley by the USGS. 40 shots were fired at 7 different shot points. Over 100 portable seismic sensors were spaced out between 0.5 and 1 km intervals throughout the valley, over 1300 recording location were used, and over 3000 seismograms were recorded. A structure and tectonic map of Imperial Valley was created from the data.
