Nowcasting Earthquakes With Stochastic Simulations: Information Entropy of Earthquake Catalogs
Earth and Space ScienceEarthquake nowcasting has been proposed as a means of tracking the change in large earthquake potential in a seismically active area. The method was developed using observable seismic data, in which probabilities of future large earthquakes can be ...

Magnitude Distribution During Transformational Faulting: Implication for Deep‐Focus Earthquakes
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.Abstract Deep‐focus earthquakes occur at 300–660 km depth. Geophysical observations and deformation experiments have proposed the olivine‐spinel (wadsleyite/ringwoodite) phase transformation as the source of the mechanical instability. While geophysical observations indicate that fault geometry influences the b $b$‐values of the Gutenberg‐Richter law ...

Comparison of statistical low-frequency earthquake activity models
Earth, Planets and SpaceSlow earthquakes are slow fault slip events. Quantifying and monitoring slow earthquake activity characteristics are important, because they may change before large earthquakes occur.

Earthquake Spectra, Volume 41, Issue 3, Page 2123-2149, August 2025.This study conducts the time‐dependent seismic risk assessment of highway bridges in western Canada when subjected to Cascadia subduction earthquakes (CSE) and aftershocks (AS). The performance‐based earthquake engineering framework is extended to assess the expected annual repair cost ratio and annual restoration time of a benchmark bridge class under

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.Abstract The Ramapo Seismic Zone (RSZ) in the Northeastern United States hosts frequent but poorly understood intraplate earthquakes, potentially posing a significant hazard to the nearby New York metropolitan area. The 5 April 2024, Mw ${M}_{w}$4.8, Tewksbury, New Jersey earthquake, provides a rare opportunity to study the RSZ seismicity.

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.Abstract The 2016 Central Italy seismic sequence unfolded in an area dominated by normal faulting along the Apennines. Our study models this complex sequence to explore the role of fluids and aseismic slip in triggering small seismic swarms. Leveraging a high‐resolution earthquake catalog, we apply a three‐dimensional density‐based clustering approach ...

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.Abstract Dynamic triggering of earthquakes is when seismic waves from earthquakes induce seismic activity at a distance. The observability of the seismic wave stresses and their results presents a unique opportunity to understand earthquake interactions and associated hazard implications.

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.Abstract We develop an earthquake simulator to study the partitioning of seismic/aseismic slip and dynamics of Earthquakes on a Heterogeneous strike‐slip Fault (HFQsim) using a generalized model of a discrete fault governed by static/dynamic friction and creep in an elastic half‐space.

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 3, March 2025.Abstract The frequency/magnitude distribution of earthquakes can be approximated by an exponential law whose exponent (the so‐called bvalue ${b}_{\mathit{value}}$) is routinely used for probabilistic seismic hazard assessment. The bvalue ${b}_{value}$ is commonly measured using Aki's maximum likelihood estimation, although biases can arise from the ...
