摘要
本文利用地震波资料,对1988年11月6日澜沧—耿马大震孕育过程中,震区及周围地区应力场(方向和强度)时空调整变动进行了分析研究。资料表明,在大震孕育发展的不同阶段,震区及周围应力场调整变动有着不同的表现特征。本文还对依据应力场时空调整变动在大震前作出的中期预测与震后检验进行了分析讨论。
In this paper, based on the seismic wave data an analytic research is done on the temporal-spatial adjustment variations of stress field (direction and strength) in the seismic area and its vicinities in the seismogenic process of The Nov. 6 , 1988, Lancang-Gengma earthquake. The obtained data indicate that the stress field variations in various slages of the seismogenic process differ greatly. Lastly, an analytic discussion is done on the intermediate-term prediction and its inspection afterward, which had been made in the light of temporal-spatial adjustment variations of stress field before the great event.
