1992年6月发生的兰德斯地震使南加利福尼亚的应力重新分布,导致一些地区发生的小震减少而邻近区域的地震活动增强,这种情况一直持续到现在。该地震也改变了大小地震的比例,在其震中约100km的范围内发生了更多的小震。这意味着南加利福尼亚未来地震的概率估值由于兰德斯地震而发生了变化。南加利福尼亚大地震发生概率增大最多的地方是随后在1999年10月赫克托矿7.1级地震中滑动最大的那个地区。

南加利福尼亚圣哈辛托(sJ)-埃尔西诺(E)断层带上的局部最小复发时间 T_L(M)与历史主震的位置相关。我们把由局部频次-震级分布(在 sJ 和 E 断层带上距每点分别6和10km 以内的地震)中的 b 值和 a 值计算出的 T_L(M)定义为复发时间。我们提出用异常低的 T_L(M)值来勾画凹凸体。6次历史主震(1899～1968)中,有5次破裂了由我们完全利用现代地震目录(M≥1.2,1981.0～1998.8)的方法勾画出的4个凹凸体的实体部分。我们估算出随机发生这种相关的概率约为10^(-2)～10^(-3),这依赖于估算的方法而有所不同.看来 T_L(M)的最小值对 b 值的最小值比对 a 值的最大值依赖性更大。因此,低 b 值的位置也可用于说明凹凸体的可能位置及主震最可能发生的地点。安扎空区为圣哈辛托断层上具有低 a 值的一段,用我们的方法勾画为一个凹凸体。b 值的不均匀性在整个研究区域都很强。在10km 的距离上,b 值的范围为0.5～1.8。b 值近似为常数的体积半径 r=8±6km。我们的结果认为,在半径为几千米的体积内对 b 值及局部复发时间的详细勾图揭示出了迄今为止用传统地震活动性分析方法未能获得的有关区域地震危险性的重要信息。

2017年11月发生在韩国东南的浦项市MW5.5地震,是过去一个世纪里韩国境内最大、最具破坏性的地震之一。此次地震距增强型地热发电厂非常近,在地震前两年期间该地热厂内的高压注水活动比较频繁,这意味着该地震有可能是人为诱发地震。本文中,我们将地震和大地测量数据相结合,研究了主震及较大余震的特征,限定了地震序列的几何分布,分析了引发地震的可能原因。根据我们的分析,此次浦项地震有可能是受人类工业活动影响所致。最后,我们发现该地震有可能将静应力传导至邻近更大的断层上,增加了邻区的地震危险性。

“地震可预测性合作研究”(CsEP)计划是一个对地震预测模型和预测算法开展前瞻性评估的全球信息化基础设施平台。CsEP的目标旨在提高我们对地震可预测性的理解、推进预测模型的研发、检验关键科学假设及其预测能力,以及改进地震危险性评估水平。自2007年在美国加利福尼亚州成立以来,全球CsEP合作一直在不同的构造环境及全球范围内进行预测实验,目前在四大洲运行4个检验中心,根据预期数据自动、客观地评估模型。这些实验为可操作的地震预测系统和地震危险性模型提供了大量的结果,并为地震的可预测性提供了新的、有时是令人惊讶的见解,还拒绝了对模型的改进。CsEP还开展了评估地震动和危险性模型的初步研究。本文报告了CsEP十年来取得的部分成就,并提出了未来地震活动性优先考虑的事项。
