9628615 Hawman This research involves seismic and potential-field investigations to improve resolution of seismogenic crustal features in basement rocks below the Paleozoic thrust sheets in eastern Tennessee. The Eastern Tennessee Seismic Zone (ETSZ) is a pronounced zone of earthquake activity in a region 300 by 50 km with earthquake hypocenters extending from 5 to 25 km in depth. The zone produces the second highest release of seismic strain energy east of the Rocky Mountains and is unique in that it is associated with regional-scale potential-field (gravity and magnetic) anomalies. Seismic recording of quarry blasts will be done to test the feasibility of this technique for the study of crustal structure. Concurrently, analysis and inversion of existing potential field data will be done. Seismic and potential-field data analysis will be integrated to provide a better understanding of structures responsible for earthquakes within the region and outline the best approach for further efforts. This research is a component of the National Earthquake Hazard Reduction Program. ***

9628615 HAWMAN这项研究涉及地震和潜在的场调查，以改善田纳西州东部古生代推力片以下地下岩石中的地震构造特征的分辨率。 田纳西州东部地震区（ETSZ）是300 x 50 km区域的地震活动区，地震低中心的深度从5到25 km。 该区域产生落基山脉以东的地震应变能的第二高释放，其独特之处在于它与区域尺度的势场（重力和磁性）异常相关。 将进行采石爆炸的地震记录，以测试该技术对地壳结构研究的可行性。 同时将对现有潜在现场数据进行分析和反转。 将集成地震和潜在的田间数据分析，以更好地理解该地区内地震的结构，并概述了进一步努力的最佳方法。 这项研究是国家地震危害计划的组成部分。 ***
