Investigation of the Seismicity, Structure and Tectonics of Asia through the Analysis of Data from Regional Seismic Networks

这项研究是1989年由莫斯科地球物理研究所的地震学家开始的一个项目的延续，该项目利用苏联在中亚天山的地震阵列数据。目的是描绘这个主要大陆碰撞特征的地震活动性、结构和构造。迄今为止的结果包括地震震中分散的显著减少和天山的三维速度模型。进一步的工作将集中在地壳和上地幔不连续面转换相的波形模拟、表面波的横波速度分析和SKS的各向异性研究。这项研究是国家减少地震危害计划的一个组成部分。

This research is a continuation of a project begun in 1989 with seismologists of the Institute of Physics of the Earth in Moscow to exploit USSR seismic array data in central Asia: the Tien Shan. The objective is to delineate the seismicity, structure, and tectonics of this major continental collisional feature. Results to date include a significant reduction of earthquake epicenter scatter and 3-D velocity models of the Tien Shan. Further work will concentrate on wave-form modelling of converted phases from discontinuities in the crust and upper mantle, shear- wave velocity analysis from surface waves, and anisotropy investigations from SKS. This research is a component of the National Earthquake Hazard Reduction Program.
