1976年唐山7.8级地震地电阻率和地下水前兆综合物理机制研究①

Abstract

Abstract: Based on the long-term observation, this paper deals with the new progresses in re-searching the comprehensive mechanism of precursors in apparent resistivity and water table associated with 1976 Tangshan earthquake （M=7. 8), and gives better understand-ing to some puzzling questions in the case study of Tangshan earthquake. The questions are as follows: ①The descending changes both in apparent resistivity and water table in the case study seem to be a“conflict" physical explanation;②the fact of sharp contrast in the seasonal changes in Baodi station (77 km away from Tangshan) before and after Tang-shan earthquake needs to be explained.

Key words: Apparent resistivity, Water table, True resistivity, Aquifer, Ground-water
