Magnitude-Dependent Omori Law: Empirical Study and Theory

open access: yes, 2004
We propose a new physically-based ``multifractal stress activation'' model of earthquake interaction and triggering based on two simple ingredients: (i) a seismic rupture results from activated processes giving an exponential dependence on the local ...

2025 U.S. Geological Survey National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands: Overview of Model and Hazard Results

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
The U.S. Geological Survey recently updated the National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). The first version of the PRVI NSHM was released in 2003, and therefore this 2025 update includes over 20 years of new geologic, geophysical, and engineering data, methods, and models.

Estimating Secondary Earthquake Aftershocks from Tsunamis

open access: yesGeosciences
Nonlinear solitary waves influence the Earth’s crust because wave pressure on the ocean bottom contains non-hydrostatic components. Our physical-mathematical model allows us to calculate the surplus super-hydrostatic pressure on the Earth’s crust.

Evolution of aftershock sequence of December 20, 2018 strong earthquake (Mw = 7.3) and its reflection in Vp/Vs-parameter field

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2020
The paper presents the results of calculations, as well as further analysis of the kinematical parameter Vp/Vs in the source area of the strong earthquake (Mw = 7.3), which occurred on December 20, 2018 at the junction of the Kurile-Kamchatka and ...

From Warnings to Actions: Factors Influencing Response to Earthquake Early Warning—A Systematic Literature Review

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
Earthquake early warning (EEW) systems offer critical seconds for protective actions, yet their effectiveness ultimately depends on human interpretation and response. This article presents a systematic literature review of factors shaping public behavior during earthquakes and in response to EEW alerts.

Seismicity, Repeating Earthquakes, and Tomographic Imaging of the Blanco Transform Fault System, Northeast Pacific

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract The Blanco transform fault system (BTFS) represents an evolving transform plate boundary in the Northeast Pacific Ocean. Its seismic behavior was captured with a dense network of 54 ocean‐bottom seismometers (OBS) operated for 1 year. We created a high‐resolution earthquake catalog based on different machine‐learning onset pickers.

Fault Volume Digital Twin to Reproduce the Full Slip Spectrum, Scaling, and Statistical Laws

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Seismological and geodetic observations of fault zones reveal diverse slip dynamics, scaling, and statistical laws. Existing mechanisms explain some but not all of these behaviors. We show that incorporating an off‐fault damage zone—characterized by distributed fractures surrounding a main fault—can reproduce many key features observed in ...

Shear‐Wave Splitting Measured for Permanent Reservoir Monitoring Systems: An Example From the Snorre Field

open access: yesGeophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Microseismic monitoring of offshore CO2$\rm CO_2$ storage projects is likely to include some deployment of offshore sensors. To improve the value proposition of this monitoring infrastructure, it is important to consider what other information can be gained about the CO2$\rm CO_2$ storage complex and the surrounding region.

DEFORMATION INTERACTION OF STRONG EARTHQUAKES OF 2010–2016 IN THE ZONE OF INFLUENCE OF THE HIKURANGA SUPERPLUME (NEW ZEALAND) ACCORDING TO GPS OBSERVATIONS

open access: yesГеодинамика и тектонофизика
Between 2010 and 2016, a series of 11 strong M>6 earthquakes occurred in New Zealand. In the area covering the epicentral zones of these seismic events, the spatiotemporal characteristics of movements and deformations of the Earth’s crust were ...

Researching Rupture: Engaged and Ethical Research on Extreme Nature–Society Disruption

open access: yesAntipode, Volume 58, Issue 3, May 2026.
Abstract Global escalation in social and environmental disruption raises crucial methodological and ethical questions for researchers working in impacted communities. Interpretive social science and humanities research can make visible the experiences of those living through socio‐ecological “rupture”.
