靠近深水地槽的安德山脉地区由北向南,即由北纬2°向南纬42°伸延。根据日德科夫划定的安德山脉地区地貌构造线图,东面限界是最靠近海岸的一级区域构造线。借助格维希阿尼的“地壳”模型的算法,上述我们所研究地区地貌构造区域构造线交点可分成:一类是附近可能有强震(B-目标)的交点;另一类是附近可能没有强震的交点。我们把震级 M≥7.75和震源深度 h≤100公里的地震叫做强震。所得分类与发生强震的可能地点的关系被已经发生过强震的交点研究资料(数集 B_0)不存在误差所证实,同时也由一系列检验实验的肯定结果所证实。所得分类与龙尼茨(C.Lomnitz)所述 M≥8.0历史地震
The Andean region near the deep water trough extends from north to south, that is, from latitude 2 ° north latitude to 42 ° south latitude. According to the delineation of the topography of the Andean region by the Lodekov, the east boundary is the first-level regional tectonic line closest to the coast. Using the algorithm of Gevichiani’s “crustal” model, the intersections of the tectonic lines in the geomorphic tectonic regions in the above study areas can be divided into the following types: one is the intersection of nearby strong earthquakes (B-targets); the other is the nearby possible No strong earthquake intersection. We call the earthquake magnitude M ≥ 7.75 and source depth h ≤ 100 km as strong earthquakes. The relationship between the classification and the possible place where strong earthquakes occurred is confirmed by the absence of errors in the intersection data (number set B_0) of the strong earthquakes that have occurred, as well as the positive results of a series of test experiments. The classification is consistent with the M ≧ 8.0 historical earthquakes described by C. Lomnitz
