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考察中获得的大量数据，这些地震考察是地球上最大的、但最不为人所知的特征之一——青藏高原。这个大而高且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，沿青藏高原从拉萨到格尔木的南北公路部署了11个宽带pascal站，为期12个月。尽管后勤和物理方面的困难令人望而畏惧，但在与中国科学家的合作下，ppi正在成功地操作该阵列，并在头几个月开始制作历史数据集。包括接收函数分析、表面波分析和折射分析在内的几种新的分析技术将应用于通过IRIS数据中心提供给所有科学家的数据。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 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.
