Episodic Seismicity Bursts Driven by Magma Intrusion During the 2025 Santorini‐Amorgos Seismic Crisis

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The 2025 Santorini–Amorgos seismic crisis in Greece had an exceptionally large number and sustained rate of moderate‐sized earthquakes. We used a machine‐learning‐based earthquake monitoring workflow to detect and relocate 66,109 earthquakes and interpret the results in the context of global analogs.

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.

Hazard Model: Epidemic-Type Aftershock Sequence (ETAS) Model for Hungary

Applied Sciences, 2023
In this article we present a space–time epidemic-type aftershock sequence (ETAS) model for the area of Hungary, motivated by the goal of its application in insurance risk models.

A Likelihood‐Free Framework for Seismic Forecasting Models: Application to Incomplete ETAS Model via Simulation‐Based Inference

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Recent advances in deep‐learning‐based earthquake detection have revolutionized seismology, producing high‐resolution catalogs complete down to very low magnitudes. While these data sets offer an unprecedented view of seismic triggering, their massive scale and inherent short‐term incompleteness pose a major challenge for traditional ...

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.

The Centenary of the Omori Formula for a Decay Law of Aftershock Activity.

Journal of Physics of the Earth, 1995
The Omori formula n(t)=K(t+c)-1 and its modified form n(t)=K(t+c)-P have been successfully applied to many aftershock sequences since the former was proposed just 100 years ago. This paper summarizes studies using these formulae. The problems of fitting these formulae and related point process models to observational data are discussed mainly.

Multifractal Omori law for earthquake triggering: new tests on the California, Japan and worldwide catalogues [PDF]

Geophysical Journal International, 2009
The Multifractal Stress-Activated (MSA) model is a statistical model of triggered seismicity based on mechanical and thermodynamic principles. It predicts that, above a triggering magnitude cut-off $M_0$, the exponent $p$ of the Omori law for the seismic decay of aftershocks is a linear increasing function $p(M) =a M+b$ of the main shock magnitude $M$.

“I Wish I Had Better Answers”: Organizational Ignorance in US Criminal Courts

Sociological Forum, Volume 41, Issue 3, Page 396-411, September 2026.
ABSTRACT Systems of monetary sanctions in US criminal courts present an opportunity for furthering the sociological understanding of complex and consequential organizations. We examine whether and how court actors across eight states understand the organizational processes supporting the fiscal logic of legal financial obligations (LFOs).

Can Domain‐Informed Design Improve Neural Spatio‐Temporal Point Processes for Earthquake Forecasting?

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Statistical earthquake forecasting models, such as the Epidemic‐type Aftershock Sequence (ETAS), embed decades of empirical knowledge and assumptions about earthquake triggering, clustering, and catalog completeness. In contrast, neural spatio‐temporal point process (STPP) models often treat seismicity as generic spatiotemporal data without ...

Geometric Moment Modulated and Maximum Entropy Informed Earthquake + Afterslip Sequences

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Synthetic earthquake sequences may be of interest for comparisons with seismicity and afterslip evolution from instrumental observations and deeper time paleoseismic event histories, as well as for forecasting purposes. Here, we describe a constructed method, independent of continuum mechanics, for generating long‐duration earthquake and ...
