Geological and geomorphological criteria for the areas prone to the earthquakes with magnitudes M ≥ 7.0 are determined for the territory of the Hellenides located in the southern part of the Balkan Peninsula. Intersections of morphostructural lineaments identified by the morphostructural zoning method are considered as seismogenic structures. Geological and geomorphological parameters were determined in a unified manner for all lineament intersections. It is established that earthquake epicenters with М ≥ 7.0 are confined to the intersections of lineaments. The intersections associated with the observed earthquakes with М ≥ 7.0 are used for training the recognition algorithm Cora-3. Based on the geological and geomorphic parameters, the recognition algorithm revealed the characteristic traits according to which all the lineament intersections were classified into the highly seismic (H) (historically called as dangerous, D) and low seismic (L) (historically called non-dangerous (N)) relative to the threshold magnitude М0 = 7.0. As a result, all these intersections were recognized as dangerous, just as another 24 intersections at which the events with magnitude M ≥ 7.0 have not been previously observed. In particular, these intersections are recognized on the Evia Island where the western branch of the North Anatolian fault approaches the coast of Central Greece. Another group of D-intersections is located in the central part of the Gulf of Corinth, the tectonically most active area of the region where, however, the earthquakes with M ≥ 7.0 have not been detected so far. The characteristic traits of D- and N-intersections (seismicity criteria) are formed by the morphometric parameters. The intervals of values of these parameters that are characteristic of D-intersections hint to the processes of subsidence and extension predominant in the areas of these intersections.

希腊 Hellenides 的强 (M ≥ 7.0) 地震多发区

对于位于巴尔干半岛南部的希腊人领土，确定了 M ≥ 7.0 级地震易发地区的地质和地貌标准。通过形态结构分区法确定的形态结构线的交点被认为是发震构造。所有线条交叉点的地质和地貌参数都以统一的方式确定。已确定 М ≥ 7.0 的地震震中仅限于线条的交点。与观测到的 М ≥ 7.0 地震相关的交叉点用于训练识别算法 Cora-3。根据地质和地貌参数，识别算法揭示了所有线状交叉点相对于地震的特征特征，将其分为高地震（H）（历史称为危险，D）和低地震（L）（历史称为非危险（N））。阈值幅度 М0 = 7.0。结果，所有这些路口都被认为是危险的，就像另外 24 个路口以前没有观察到 M ≥ 7.0 的事件一样。特别是，在北安纳托利亚断层的西支靠近希腊中部海岸的埃维亚岛上可以识别这些交叉点。另一组 D 型交叉口位于科林斯湾的中部，该地区是该地区构造最活跃的区域，但迄今为止尚未探测到 M ≥ 7.0 的地震。D-和N-交叉点（地震标准）的特征是由形态测量参数形成的。作为 D 型交叉口特征的这些参数值的区间暗示了在这些交叉口区域占主导地位的沉降和伸展过程。
