Collaborative Research: Lithospheric Structure of the Tibetan Plateau

这项研究是为了分析从一次成功的地震探险到地球上最大但最不为人了解的地貌之一--青藏高原--的大量数据。这个面积大、高度高、地震活跃的地区是印度大陆与欧亚大陆碰撞的结果。1991年夏天，11个宽带PASSCAL站在一条横跨青藏高原的拉萨至格尔木南北公路上部署了12个月。尽管存在巨大的后勤和物质困难，但PIS与中国科学家合作，成功地操作了该阵列，并在最初几个月开始制作历史数据集。包括接收函数分析、面波分析和折射分析在内的几种新的分析技术将被应用于这些数据，这些数据将通过IRIS数据中心向所有科学家提供。这项研究是国家减少地震灾害计划的一部分。

This research is to analyze a wealth of data from a successful seismic expedition to one of the largest, but least understood features of the earth, the Tibetan Plateau. This large, high and actively seismic area is a result of the collision of the Indian continent with Eurasia. Eleven broad-band PASSCAL stations were deployed in the Summer of 1991 for 12 months along a north-south road across the Tibetan Plateau from Llasa to Golmud. In spite of daunting logistical and physical difficulties, the PIs', in cooperation with Chinese scientists, are successfully operating the array and have in the first few months, begun the production of an historical data set. Several new analysis techniques including receiver function analysis, surface-wave analysis, and refraction analysis will be applied to the data which will be available to all scientists through the IRIS Data Center. This research is a component of the National Earthquake Hazard Reduction Program.
