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

AGU Advances, 2021 Earthquake triggering by seismic waves has been recognized as a phenomenon for nearly 30 years. However, our ability to study dynamic triggering has been limited by our ability to capture the triggering stresses accurately and record the resultant ...

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.

A spatio-temporal analogue of the Omori-Utsu law of aftershock sequences
, 2021 A spatio-temporal version of the well-known Omori-Utsu law of aftershock sequences is proposed. This 'diffusive Omori-Utsu law' satisfies a nonlinear partial differential equation (PDE). A similarity reduction is obtained that reduces the PDE to an ordinary differential equation (ODE).

Frontiers in Earth ScienceForeshocks and aftershocks occurred before and after the ML6.8 (Mw7.0) earthquake in eastern Taiwan on 18 September 2022. We explore the epicentral distribution and temporal variations for the mainshock, foreshocks, and aftershocks.

Partial Ruptures, Cascading Multi‐Fault Ruptures, and Aftershocks in 2D Random Fault Network
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The Gutenberg‐Richter law for the distribution of earthquake magnitude and the Omori law for the decay of aftershocks are two universal laws in seismicity. Although numerical models have been developed to reproduce these laws, they sometimes produce many more foreshocks and fewer aftershocks than observed.

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Swarms are microearthquake clusters governed by aseismic deformation, fluid migration, and stress changes, but the underlying mechanisms for their recurrence remain elusive. In 2008, abundant swarms were observed on the westernmost Gofar transform fault.

Journal of Rock Mechanics and Geotechnical EngineeringThe control and management of mining-induced seismic hazards have attracted ever-rising attention, especially in underground longwall coal mines, where continuous mining activities dynamically alter the stress states and induce seismic events.

Thermally Activated Static Friction Can Explain Earthquake Interactions
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Unlike meteorological hazards, tectonic earthquakes remain hardly predictable, reinforcing their deadly character. This relates to an out‐of‐equilibrium, intermittent dynamic associated with a strong time asymmetry, with few and non‐systematic foreshocks sometimes preceding large earthquakes, while aftershocks are ubiquitous and have been ...

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract In 2022–2023, three local‐magnitude (ML) 4.8–5.6 earthquakes shook the Peace River oilsands area of Alberta, Canada. Previous studies statistically linked the seismicity to nearby disposal activities but lacked in‐depth investigation into triggering mechanisms, including subsurface fluid migration and earthquake interaction.
