Annals of Geophysics, 2004 A damaging earthquake of Mw 7.7, which struck the Bhuj region of India on January 26, 2001, was followed by a large number of aftershocks. The aftershock data available at Gauribidanur Seismic Array Station (GBA), India, till 869 h following the main ...

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 13, Page 3264-3284, 25 October 2026.ABSTRACT Conventional single intensity measure (IM) fragility approaches with simplified component dependency assumptions overlook the progressive damage accumulation and evolving inter‐component correlations that govern system behavior under mainshock‐aftershock (MSAS) loading.

Variations in precursory slip behavior resulting from frictional heterogeneity
Progress in Earth and Planetary Science, 2018 Precursory seismicity is often observed before a large earthquake. Small foreshocks occur within the mainshock rupture area, which cannot be explained by simple models that assume homogeneous friction on the entire fault.

Aftershock Rate Changes at Different Ocean Tide Heights
Frontiers in Earth Science, 2020 The differential probability gain approach is used to estimate quantitatively the change in aftershock rate at various levels of ocean tides relative to the average rate model.

Omori‐like decay of postseismic velocities following continental earthquakes
Geophysical Research Letters, 2017 Various mechanisms have been proposed to explain the transient, enhanced surface deformation rates following earthquakes. Unfortunately, these different mechanisms can produce very similar surface deformation patterns leading to difficulty in ...

Dependence of the Omori‐Utsu law parameters on main shock magnitude: Observations and modeling [PDF]
Journal of Geophysical Research: Solid Earth, 2008 We examine the dependence on main shock magnitudemof thepandχparameters appearing in Omori‐Utsu formulaλ(t,m) =χ× (t+c)−prelating the rate of aftershocksλat timetafter a main shock. Observations point out to a significant increase ofpwithm, along with a scaling relationship of the formχ∼ 10αm.

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Modeling earthquake clustering in space and time is central to understanding seismicity patterns and improving forecasting. The Epidemic‐Type Aftershock Sequence (ETAS) model, grounded in the Hawkes process, has long been the standard approach for describing aftershock triggering through fixed, empirically defined kernel functions.

The Analysis of the Aftershock Sequences of the Recent Mainshocks in Alaska
Applied Sciences, 2022 The forecasting of the evolution of natural hazards is an important and critical problem in natural sciences and engineering. Earthquake forecasting is one such example and is a difficult task due to the complexity of the occurrence of earthquakes. Since

Residual Strain Mechanism of Aftershocks and Exponents of the Modified Omori's Law [PDF]
Journal of Geophysical Research: Solid Earth, 2019 AbstractThe rate of aftershocks caused by residual stresses left after a major seismic event or material failure is considered. It is assumed that the local (or “micro” with respect to the scale of the major event) failures registered as aftershocks are produced by static fatigue (delayed fracture).
