引言巴基斯坦北部的科希斯坦地区(35°—37°N,72°—76°E),处于哈扎拉弧强烈变形部位以北的喜马拉雅碰撞带范围内。该地区代表了喜马拉雅前沿的西北端和帕米尔强烈活动部位的南部地区。了解科希斯坦地区的地震活动性,对于认识中亚和更南部地区的强烈形变活动之间的关系,具有重要意义。自世界标准地震台网于六十年代初期设置以来,科希斯坦地区只发生了三个重要地震 Introduction The Korshitan area (35 ° -37 ° N, 72 ° -76 ° E) in northern Pakistan is within the Himalayan collision zone north of the strongly deformed Hazara arc. The area represents the northwestern tip of the Himalayan frontier and the southern part of the Pamir strong activity. Understanding the seismicity in the Košistan region is of great importance for understanding the relationship between the intense deforming activities in Central Asia and in the southern region. Since the establishment of the world standard seismic network in the early 1960s, only three major earthquakes occurred in the Koskirchen region
