Predicting largest expected aftershock ground motions using automated machine learning (AutoML)-based scheme [PDF]

Scientific Reports
Aftershocks 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 ...

Are Aftershocks of Large Californian Earthquakes Diffusing? [PDF]

, 2003
We analyze 21 aftershock sequences of California to test for evidence of space-time diffusion. Aftershock diffusion may result from stress diffusion and is also predicted by any mechanism of stress weakening.

Properties of Foreshocks and Aftershocks of the Non-Conservative SOC Olami-Feder-Christensen Model: Triggered or Critical Earthquakes? [PDF]

, 2003
Following Hergarten and Neugebauer [2002] who discovered aftershock and foreshock sequences in the Olami-Feder-Christensen (OFC) discrete block-spring earthquake model, we investigate to what degree the simple toppling mechanism of this model is ...
