This research is to study the continental collision between India and Eurasia which, because of the enormous scales involved, provides one of the best opportunities for investigating seismogenic continental tectonics in a wide variety of environments. Most of the data to be used are the under-utilized seismic records of the former Soviet Union in cooperation with a Russian research group at Institute of the Physics of the Earth headed by Dr. Vinnik. Objectives of the study are 1) to investigate the nature of the phase transitions in the mantle beneath different parts of Asia and determine their relationships to regional tectonics, 2) to investigate buoyancy forces in the generation of the Tien Shan by means of earthquake source parameters, 3) to investigate the nature of the upper mantle beneath the Caucuses, Baikal region, and Tibet through the analysis of S and SS phases, 4) to investigate the structure of the crust and upper mantle in the Altai region through travel-time tomography and receiver-function analysis, and 5) to investigate Kurile- Kamchatka subducting slab structure. This research is a component of the National Earthquake Hazard Reduction Program.

这项研究是为了研究印度和 和欧亚大陆，由于涉及的巨大规模， 提供了一个最好的机会， 在各种各样的地震大陆构造 环境. 大多数要使用的数据是未充分利用的数据 前苏联的地震记录， 俄罗斯地球物理研究所研究小组 由Vinnik博士领导 本研究的目的是：（1） 研究地幔相变的本质 在亚洲不同地区的地下， 区域构造，2）调查浮力在 通过震源生成天山 参数，3）研究上地幔的性质 在高加索山脉，贝加尔湖地区和西藏，通过分析 （4）研究地壳结构 利用走时层析成像研究阿尔泰地区上地幔和地幔 和接受者功能分析，以及5）调查Kurile- 堪察加俯冲板状构造。 这项研究是 国家地震减灾计划。
