摘要:
通过对永安—晋江断裂带开展致灾因子风险调查,逐一查明带内各次级断裂的规模、产状、活动性质和最新活动时代,结合地震活动特征和构造应力场,综合判定调查区内的发震构造和致灾因子,评价各致灾因子的最大潜在震级。在此基础上开展致灾因子风险区划,在调查区内划分出7个地震风险源,厘定各风险源及背景源的震级上限,为响应国家自然灾害风险普查、摸清调查区地震风险隐患底数和第六代地震动参数区划图编制提供基础资料。
Abstract:
Based on the risk investigation of disaster causing factors in Yong'an-Jinjiang Fault Zone, this paper finds out the scale, occurrence, activity nature and latest activity era of each secondary fault in the zone one by one. Combined with the characteristics of seismicity and tectonic stress field, the seismogenic structure and disaster causing factors in the investigated area are comprehensively determined, and the maximum potential magnitude of each disaster causing factor is evaluated. On this basis, the risk zoning of disaster causing factors is carried out, 7 seismic risk sources are divided in the investigated area, and the upper limit of magnitude of each risk source and background source is determined, so as to provide basic data for responding to the national natural disaster risk survey, finding out the base number of potential seismic risk in the investigated area and compiling the sixth generation seismic ground motion parameters zonation map.
