High-Resolution imaging and monitoring of the subsurface structure and seismicity at a site along the San Jacinto fault zone using a dense seismic nodal array. The site is located about 8 km southeast of the town of Anza, California. The type of nodal sensor employed is the Fairfield Zland 3-component geophone (records ground velocity continuously). The array consists of 108 sensors, with 54 located along a linear across-fault profile and the remaining 54 sensors scattered around that profile and along the fault. The array spans a 1800 m by 800 m area.
