地热涡合并与1976年唐山大地震

THE MERGER OF GEOTHERMAL VORTEXES AND THE TANGSHAN EARTHQUAKE IN 1976

摘要:

分析了1976年唐山大地震前的地热涡活动,研究了地热涡活动与唐山大地震的关系,追踪了有关地热涡的发展演化史及其合并活动对有关地震的影响.研究表明,唐山大地震前我国大华北地区有巨大的地热涡群活动,与邢台地震前地热涡的成群聚集类似,并且同样在地震爆发前发生地热涡合并.这一现象是大华北地区强地震发生的重要前期事件之一.

Abstract:

In this paper,the geothermal vortex action before the Tangshan earthquake in 1976 and relation between it and the Tangshan earthquake are analysed.The results are as the follows:There is a geothermal vortex crowd in north China before the Tangshan earthquake in 1976,which is similar to that before the Xingtai earthquake in 1966.And all geothermal vortexes have merged into great one before the earthquake.This is one of the important event before strong earthquake occurred in north China.
