本文在对河北省北部包括廊坊市附近地区的地质、地貌、地震活动进行研究的基础上,应用CORA—3算法得出了图象识别的结果。通过控制试验,证明结果较稳定。本文认为河北省北部易发生地震的地点——本区的潜在震源与该区的北东—北东东,北西—北西西向断裂活动有关,隆起与拗陷的过渡地带若有此二组断裂活动或处于地震带内的话,地震发生的可能性较大。近东西向断裂由于成生较早,现今活动与地震的关系不太明显。
Based on the study of the geology, geomorphology and seismicity in the northern part of Hebei Province, including the surrounding area of Langfang City, the results of image recognition are obtained by CORA-3 algorithm. Through the control test, the result is more stable. In this paper, it is considered that the place prone to earthquakes in the northern part of Hebei Province - the potential source of this area is related to the NE-NE, NW-NNWE faults in this area. If there are any two faults in the transition zone between the uplift and the depression Or in the earthquake zone, the earthquake is more likely. The recent east-west fault due to earlier birth, the current activity and the relationship between the earthquake is not obvious.
