In order to study the spatiotemporal evolution of the precursory anomalies 10 years before the Wenchuan M_S8. 0 earthquake in 2008, the epicentral distance of the precursory anomalies is calculated by using the geometric center of the rupture region an

在2016年新西兰凯库拉M_W 7.8地震中,北东—北东东向科科仁古断裂水平右旋位移量最大,为10—12m;北北西—近南北向帕帕提断裂垂直位移量最大,达到5—6m。对直接坐落在这2条地震地表破裂带或变形带之上的建筑物的破坏现场调查表明,尽管房屋出现歪斜,但上部主体部分基本完整,没有出现倒塌或部分倒塌现象,避免了人员伤亡。在无法回避活动断裂及其大震危险性的情况下,隔震系统的广泛采用可以有效地提高建筑

本文对1880年以来首都圈5级以上地震的时空特征进行分析,认为首都圈地区5级以上地震活动存在10年左右的周期性,地震发生有自西向东迁移的特征且这一迁移具有轮回性。目前,首都圈地区处于发震的时间节点上,根据迁移性和轮回性认为未来首都圈东部地区发生5级以上地震的可能性较大。
