This research is to use existing high-resolution seismic reflection profiles and earthquake data with bathymetry and gravity measurements to study a region offshore southern California. In this active seismic area, the objective will be to delineate structures that are currently deforming and correlate them with locations of earthquakes. This area includes the site of the offshore 1986 M=5.8 Oceanside earthquake. The results will help to determine if the identification of active deformation structures can be used to estimate seismic hazard. This research is a component of the National Earthquake Hazard Reduction Program.

这项研究是利用现有的高分辨率地震反射剖面和地震数据以及水深和重力测量来研究加利福尼亚州南部近海的一个地区。在这一活跃的地震区，目标将是描绘目前正在变形的构造，并将它们与地震的位置联系起来。这一地区包括1986年近海5.8级海滨地震的现场。这一结果将有助于确定活动变形构造的识别是否可用于地震危险性评估。这项研究是国家减少地震灾害计划的一部分。
