This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The U.S. west coast is subject to significant risk of very large earthquakes, and heavily populated Southern California is particularly vulnerable owing to its proximity to the San Andreas Fault. The linkage of this fault system through the Salton Sea region is poorly understood, in part because the structure beneath the Salton Sea has not been defined. The project, conducted in conjunction with a deployment of on-land seismic stations, will address that problem by deploying an array of ocean bottom seismometers (OBS) on the floor of the Salton Sea, and conducting a complementary multi channel seismic survey aimed at imaging the structure beneath the Salton Trough. Improved understanding of the Earthquake hazard in this region has direct societal benefit. The project will also contribute to science education in California, and support the Ph.D. research of a young female graduate student at UCLA.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。美国西海岸面临着巨大的地震风险，人口稠密的南加州由于靠近圣安德烈亚斯断层而特别脆弱。这个断层系统通过索尔顿海地区的联系知之甚少，部分原因是索尔顿海下面的结构尚未确定。该项目与部署陆地地震台站一起进行，将通过在索尔顿海底部署海底地震仪阵列和进行补充性多通道地震调查来解决这一问题，目的是对索尔顿海槽下面的结构进行成像。提高对该地区地震灾害的认识具有直接的社会效益。该项目还将有助于加州的科学教育，并支持博士学位。加州大学洛杉矶分校的一名年轻女研究生的研究。
