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 ...

Aftershock prediction for high-frequency financial markets' dynamics

, 2012
The occurrence of aftershocks following a major financial crash manifests the critical dynamical response of financial markets. Aftershocks put additional stress on markets, with conceivable dramatic consequences.

Global Primary and Secondary Microseism Multi‐Decade Geographic Variation, Secular Intensification, and Period Lengthening

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Earth's long period background seismic wavefield is dominated by two distinct processes that couple ocean wave energy to a global microseism wavefield. We assess global microseism intensity in the secondary (4–10 s) and primary (14–20 s) bands, and across eight 2 s‐wide period bands between 4 and 20 s.

Engineering Applications Using Probabilistic Aftershock Hazard Analyses: Aftershock Hazard Map and Load Combination of Aftershocks and Tsunamis

Geosciences, 2017
After the Tohoku earthquake in 2011, we observed that aftershocks tended to occur in a wide region after such a large earthquake. These aftershocks resulted in secondary damage or delayed rescue and recovery activities.

Dynamic Models of Magma Storage Within a Damaging, Strain‐Softening Crust and Their Application to Sierra‐Negra's Pre‐Eruptive Inflation Pattern

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Prior to its 2005 and 2018 eruptions Sierra Negra's caldera displayed decades‐long inflation characterized by successive transient uplifts culminating in accelerating uplifts in the 1–2 years prior to each eruption. These observations motivated the question: can these transient uplifts be explained by internal dynamics of the magma system ...

An Analysis of the 2008 M_s 8.0 Wenchuan Earthquake’s Aftershock Activity

Applied Sciences
We investigated the magnitude–frequency relationship and decay pattern of an aftershock sequence using data from the 2008 Wenchuan earthquake. We analyzed the spatial variations in aftershock activity parameters b and p.

Fault Kinematics of the 2019–2026 Puerto Rico Earthquake Sequence: Conjugate Faulting Within a Zone of Oblique Subduction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The 2019–2026 southwestern Puerto Rico earthquake sequence has the characteristics of an earthquake swarm with over 9,000 events of Mw 2.5 or greater over an area of 1,500 km2, and the largest event is an Mw 6.4 on 7 January 2020. Previous studies have proposed two structural interpretations: (a) an E‐striking, N‐dipping normal fault hosting ...

Dynamic Earthquake Triggering in Southern California in High Resolution: Intensity, Time Decay, and Regional Variability

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 ...

Objective Estimation of Spatially Variable Parameters of Epidemic Type Aftershock Sequence Model: Application to California

, 2017
The ETAS model is widely employed to model the spatio-temporal distribution of earthquakes, generally using spatially invariant parameters. We propose an efficient method for the estimation of spatially varying parameters, using the Expectation ...
