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 ...

Effect of Aftershocks on Seismic Fragilities of Single-Story Masonry Structures
Frontiers in Physics, 2021 The effect of aftershocks on the fragility of single-story masonry structures is investigated using probabilistic seismic demand analysis Finite element models of an unreinforced masonry (URM) structure and a confined masonry (CM) structure are ...

Mainshock‐Aftershock Clustering in Volcanic Regions
Geophysical Research Letters, 2018 Earthquakes break their general Poissonean behavior through two types of seismic bursts: swarms and mainshock‐aftershock sequences. The former is commonly thought to dominate in volcanic and geothermal regions, but aftershock production, including within
