磁县断裂带的构造和地震活动特征
CHARACTERISTICS OF TECTONIC ACTIVITY AND SEISMICITY OF CIXIAN FAULT
-
摘要: 磁县断裂带是华北地震区中重要的断裂之一,1830年该断裂带发生了M7级地震。从分析该带的构造特征和地震活动特征出发,在结合历史地震活动和现今地震活动基础上,利用震级-时间模型对磁县断裂带未来强震活动进行预测,结果表明,未来该段中南的总体活动水平维持在5级左右。Abstract: The Cixian fault zone is one of the important earthquake faults in North China, a M7 earthquake occurred in the fault in 1830.Based on the tectonic characteristics and historical and present seismic activity, we use the magnitude-time model to calculate the probability of seismicity of Cixian fault in the future.
