LARSE

The Los Angeles Regional Seismic Experiment (LARSE) is a cooperative study of the crustal structure of southern California, conducted by earth scientists from the U.S. Geological Survey and the Southern California Earthquake Center (SCEC). The purpose of this study is to produce reflection, refraction and 3-dimensional tomographic images of the active geologic structures in the Los Angeles Region. These include the San Andreas Fault, the frontal fault system of the Transverse Ranges, blind thrust faults and folds in the Los Angeles basin and the San Fernando Valley, and strike slip faults south of the Transverse Ranges.
