Predicting largest expected aftershock ground motions using automated machine learning (AutoML)-based scheme [PDF]
Scientific ReportsAftershocks can cause additional damage or even lead to the collapse of structures already weakened by a mainshock. Scarcity of in-situ recorded aftershock accelerograms heightens the need to develop synthetic aftershock ground motions. These synthesized

Deep learning of the aftershock hysteresis effect based on the elastic dislocation theory [PDF]
Natural Hazards and Earth System Sciences, 2020 This paper selects fault source models of typical earthquakes across the globe and uses a volume extending 100 km horizontally from each mainshock rupture plane and 50 km vertically as the primary area of earthquake influence for ...

Aftershocks and Fluctuating Diffusivity
Entropy, 2023 The Omori-Utsu law shows the temporal power-law-like decrease of the frequency of earthquake aftershocks and, interestingly, is found in a variety of complex systems/phenomena exhibiting catastrophes. Now, it may be interpreted as a characteristic response of such systems to large events.

Study on the sequence activities of the 2021 Yangbi MS 6.4 earthquake in Yunnan
Frontiers in Earth Science, 2023 On 21 May 2021, the MS 6.4 earthquake struck Yangbi County, Dali City, Yunnan Province. Minor seismic activities were common both before and after the earthquake; the foreshock sequence activity characteristics of this earthquake were studied to gain a ...

Dizhen xuebao, 2021 利用2014年10月至2019年9月期间欧空局Sentinel-1卫星采集的合成孔径雷达数据分析了2014年2月12日新疆于田MS7.3地震的震后形变场。结果表明，此次地震造成了南硝尔库勒断裂上明显的震后形变，首次从地震形变场的角度验证了此次地震的发震构造为NE向的左旋走滑断裂，而非部分研究所认为的近NS向断裂。由合成孔径雷达干涉测量得到的多年平均速率图显示主震的西侧仅出现了少量震后余滑且仍为强闭锁区，这意味着2008年和2014年于田两次MS7.3地震之间的区域仍存在发生强震的风险 ...
