摘要
福州市是福建省的省会,毗邻我国最强烈的地震活动带——台湾板块边界活动构造带,是否会发生大地震也一直为民众担忧。研究区属中国大陆浙闽粤隆起带,发育北东向、北东东向和北西向等一系列断层。通过对福州地区的地震活动、主要断层活动性进行了分析,结合区域地壳稳定性,综合研究了该区地震构造环境特征。结果表明:福州地区不具备发生地表破裂型大震的构造条件,但不排除发生中等–中强地震的可能性,为福州地区的防震减灾工作提供依据,具有重要的现实意义。
Fuzhou, the capital of Fujian Province, is adjacent to the most intense seismic activity belt in my country—the active tectonic belt of the Taiwan Plate Boundary. Whether there will be a major earthquake has always been a concern for the public. The study area is located in Zhe-Min-Yue uplifted zone, and a series of NE, NE and NW trending faults are developed. By analyzing the seismicity and main faults activity of Fuzhou area, and combining with the regional crustal stability, the seismic structure characteristics of this area are comprehensively studied. The research shows that the Fuzhou area does not have the tectonic conditions for the occurrence of large surface rupture earthquakes, but it does not rule out the possibility of moderate-moderately strong earthquakes. The research result provides a basis for the earthquake prevention and disaster reduction work in Fuzhou, and has important practical significance.
