Market dynamics immediately before and after financial shocks: quantifying the Omori, productivity and Bath laws [PDF]

, 2010
We study the cascading dynamics immediately before and immediately after 219 market shocks. We define the time of a market shock T_{c} to be the time for which the market volatility V(T_{c}) has a peak that exceeds a predetermined threshold.

Record‐Wise Disaggregated Seismic Fragilities for Interconnected Systems

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 743-758, March 2026.
ABSTRACT Seismic risk assessment studies typically rely on fragility functions/curves to characterize the susceptibility of an asset or a class of assets to damage. These curves are essentially a summarization of responses evaluated on the basis of ground motions with record characteristics and intensities that may or may not be tied to a specific site

Spatiotemporal correlations of aftershock sequences

, 2010
Aftershock sequences are of particular interest in seismic research since they may condition seismic activity in a given region over long time spans. While they are typically identified with periods of enhanced seismic activity after a large earthquake ...

Aftershocks Preferentially Occur in Previously Active Areas

The Seismic Record, 2022
The clearest statistical signal in aftershock locations is that most aftershocks occur close to their mainshocks. More precisely, aftershocks are triggered at distances following a power-law decay in distance (Felzer and Brodsky, 2006).

Detection and Modeling of the Effect of Large Earthquakes in GRACE/GRACE‐FO Mascons

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract The usefulness of Gravity Recovery and Climate Experiment (GRACE) and GRACE Follow‐On (GRACE/FO) data products for ocean studies remains limited in a few areas, where large gravity signals from the 2011 Japan earthquake and three major earthquakes in the Andaman‐Sumatra area (in 2004, 2007, and 2012) obscure vastly smaller signals of interest ...

Renormalization of earthquake aftershocks

, 1999
Together with the Gutenberg-Richter distribution of earthquake magnitudes, Omori's law is the best established empirical characterization of earthquake sequences and states that the number of smaller earthquakes per unit time triggered by a main shock ...

Application of Singular Spectrum Analysis (SSA) for Delineating Geomagnetic and Lithospheric Signatures Associated With M7.6 Japan Earthquake

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract In this paper, Singular Spectral Analysis (SSA) is applied to the geomagnetic field to delineate signatures from different sources, such as geomagnetic variability and lithospheric processes. We performed SSA on the Y component of the Swarm satellite magnetic field By during the period from September 2023 to January 2024. Eigen values obtained

Nonstationary ETAS models for nonstandard earthquakes

, 2014
The conditional intensity function of a point process is a useful tool for generating probability forecasts of earthquakes. The epidemic-type aftershock sequence (ETAS) model is defined by a conditional intensity function, and the corresponding point ...

Contemporary Seismicity in and Around the Yakima Fold-and-Thrust Belt in Eastern Washington [PDF]

, 2012
We examined characteristics of routinely cataloged seismicity from 1970 to the present in and around the Yakima fold-and-thrust belt (YFTB) in eastern Washington to determine if the characteristics of contemporary seismicity provide clues about regional ...

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

Геодинамика 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 ...
