Aging in coherent noise models and natural time

, 2004
Event correlation between aftershocks in the coherent noise model is studied by making use of natural time, which has recently been introduced in complex time-series analysis.

Residual Strain Mechanism of Aftershocks and Exponents of the Modified Omori's Law [PDF]

Journal of Geophysical Research: Solid Earth, 2019
AbstractThe rate of aftershocks caused by residual stresses left after a major seismic event or material failure is considered. It is assumed that the local (or “micro” with respect to the scale of the major event) failures registered as aftershocks are produced by static fatigue (delayed fracture).

Unsupervised Likelihood Inference of the b‐Value via Magnitude Differences

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Estimating the Gutenberg–Richter b‐value from seismic catalogs is critical for earthquake forecasting and hazard assessment. However, traditional approaches rely on predefined magnitude thresholds and are highly sensitive to catalog incompleteness, limiting their applicability in automated or real‐time settings.

The mechanisms of spatial and temporal earthquake clustering

, 2009
The number of earthquakes as a function of magnitude decays as a power law. This trend is usually justified using spring-block models, where slips with the appropriate global statistics have been numerically observed.

Fluid Processes Highlighted by Temporal Variations of b‐Value During Swarms and Aftershocks Sequences in the Ubaye Region (Western Alps, France)

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract The b‐value from the Gutenberg‐Richter law is a crucial parameter in the assessment of seismic hazard. Its temporal variations may also bring useful insights on the processes driving seismicity at depth, even if not yet fully understood. In this paper, we focus on the temporal evolution of the b‐value in the Ubaye Region (French Western Alps ...

Reduced seismic activity after mega earthquakes

Communications Earth & Environment
Mainshocks are often followed by increased earthquake activity (aftershocks). According to the Omori-Utsu law, the rate of aftershocks decays as a power law over time.

Signatures of criticality in turning avalanches of schooling fish

Physical Review Research
Moving animal groups transmit information through propagating waves or behavioral cascades, exhibiting characteristics akin to systems near a critical point from statistical physics. Using data from freely swimming schooling fish in an experimental tank,

Scale-invariant statistics of period in directed earthquake network

, 2004
A new law regarding structure of the earthquake networks is found. The seismic data taken in California is mapped to a growing directed network. Then, statistics of period in the network, which implies that after how many earthquakes an earthquake ...
