摘要
将川滇地震区活动断裂、历史地震与地震预测经验教训等方面资料,充实地震活动图像分析预测强震趋势的方法,总结出了10项地震活动异常作为预测依据,统称为"地震活动图像异常"。利用此研究成果,从川滇推广至中、外许多震例都可以确认有这些异常图像的存在,反映出大地震孕育过程晚期,即主震前中短期阶段区域及主震破裂区应变释放的演化特征,有一定的构造物理背景。对川滇地震活动图像特征的核心——重复性及其验证效果作了分类介绍,讨论了重复性特征的机理。对强震趋势预测有一定的应用价值。
According to prediction method for strong earthquake using seismic activity,they concluded seismic anomalies as basis called seismic activity anomaly because of some historical data about Sichuan-Yunan seismic zone. The results reflected later process of strong earthquake and stress released features in main shock fracture through anomaly images of lots of earthquake cases. They also introduced characteristics of seismic repeatability and its side effect which has application value for strong earthquake prediction.
