Investigation of the Seismicity, Structure, and Tectonics ofthe Tien Shan Region of Central Asia through the Analysis of Data from a Regional Seismic Network

该项目是与苏联地球物理研究所合作进行的地震研究。该分析将使用来自苏联天山地区的大量地震数据集来精确定位地震，确定断层的方向和应力，并确定地壳和上地幔的结构。该地区是大陆内山带活跃变形的最好例子之一，与晚白垩纪科罗拉多州、犹他州和怀俄明州落基山脉的拉拉米造山运动时期类似。天山地壳变形的测定对世界其他地震区的地震发生和地震灾害有直接影响，可直接应用于国家减少地震灾害计划。

The project is a collaborative seismic study with the Institute of Physics of the Earth in the USSR. The analysis will use an extensive earthquake data set from the Tien Shan area of the USSR to precisely locate earthquakes, determine the orientation and stresses on faults, and determine the structure of the crust and upper mantle. This region is one of the best examples of an actively deforming intracontinental mountain belt and is analogous to the time of the Laramide orogeny in the Rocky mountains of Colorado, Utah, and Wyoming during the Late Cretaceous. The determination of deformation of the crust in Tien Shan bears on the occurrence of earthquakes and seismic hazard in other seismic areas of the world and thus has direct application to the National Earthquake Hazard Reduction Program.
