| 摘 要： | 昆仑山口西8.1级地震前,青藏块体出现了有序的地震图像演变过程:地震空区时间跨度数年至数十年,空间跨度数百至上千km;地震条带时间跨度数年,空间跨度数千km。1990年以后,青海、甘肃、四川、新疆、宁夏诸省的前兆观测台网记录到一批典型的远场前兆异常,这些趋势性异常变化与孕震空区、地震条带形成时段大致相当;空间上主要分布在祁连山构造带、东昆仑构造带、西秦岭构造带、南北构造带及天山构造带。远场前兆异常与空区图像的时空演变有较好的互补性和关联性,文中讨论了两者演化的有序性和阶段性与昆仑山口西8.1级地震孕育的时空过程

| Abstract: | Before the MS 8.1 West Kunlun Mountain Pass earthquake,an orderly evolution of seismicity patterns was observed in the Qinghai-Tibet block:the evolution of seismic gaps showed a time span of several to decades of years and a space span of hundreds to thousands of kilometers,and that of seismic stripes had a time span of several years and a space span of thousands of kilometers.After 1990,the seismic precursory observation networks in Qinghai,Gansu,Sichuan,Xinjiang and Ningxia Provinces and autonomous region... |
