摘　　要：2001年11月14日,在青海昆仑山口西沿近东西向断裂发生了Ms8.1巨大地震,地震造成近东西走向地表断裂带长达350公里,锦州台体应变记到8.1级地震波动长达10个小时,可见8.1地震释放能量的巨大。它必然加速附近地区的应力积累,引发较近地区地震的快速发生,也会激发周边发生远震效应。历次震例表明,强震前后的地震活动,形变及其他地球物理场的变化往往是大范围的,提出一种大尺度的地震孕育过程模式显然是需要的。On November 14, 2001, a huge earthquake （Ms8.1） shattered the mouth of Kunlun Pass in Qinghai Province, causing a 350-km long surface rupture, and releasing great energy. Jinzhou Seismic Station observed the earthquake wave for 10 hours. The earthquake may accelerate the stress accumulation and provoke more earthquakes in the vicinity and even in distant areas. History records show that seismic activities before and after strong earthquakes, the deformation and other physical indexes are anomalous. As a result, a bold pattern of earthquake preparation is in need.
