Use of Seismic Reflection to Confirm a Major Buried Fault System Beneath the Coastal Plain of South Carolina

小行星9508229 这项研究是为了测试最近提出的一个400公里长的，北东北走向的断层系统，这是假设延伸通过沿海平原的卡罗莱纳州和弗吉尼亚州，通过采集四个8至10公里长的高分辨率地震反射剖面横跨其趋势在南卡罗来纳州的存在。 剖面分析的目的是寻找侏罗纪玄武岩流（约600-800米深）中可能存在的偏移的证据，并在其趋势上覆盖沉积层。 来自堪萨斯大学的一个研究小组将获取并处理这些数据。 拟议的故障系统是1886年南卡罗来纳州查尔斯顿的因果故障的候选者，地震 这项研究是国家地震减灾计划的一个组成部分。 ***

9508229 TALWANI This research is to test the existence of a recently proposed 400-km-long, north northeast-trending fault system, which is postulated to extend through the Coastal Plain of the Carolinas and Virginia, by acquiring four 8- to 10-km-long high-resolution seismic reflection profiles across its trend in South Carolina. The objective of the profiling is to seek evidence of possible offsets in a basalt flow (about 600-800 m depth) Jurassic in age and in overlying sedimentary layers across its trend. A team from the University of Kansas will acquire and process the data. The proposed fault system is a candidate for the causal fault of the 1886 Charleston, S.C., earthquake. This research is a component of the National Earthquake Hazard Reduction Program. ***
