Comparing foreshock characteristics and foreshock forecasting in observed and simulated earthquake catalogs [PDF]

Journal of Geophysical Research: Solid Earth, 2014
AbstractIn this paper, we compare the empirical results regarding foreshocks obtained from the Japan data with results for synthetic catalogs in order to clarify whether or not the corresponding results are consistent with the description of the seismicity by a superposition of background activity and epidemic‐type aftershock sequence (ETAS) models ...

3-D dynamic rupture simulations of the 2016 Kumamoto, Japan, earthquake

Earth, Planets and Space, 2017
Using 3-D dynamic rupture simulations, we investigated the 2016 Mw7.1 Kumamoto, Japan, earthquake to elucidate why and how the rupture of the main shock propagated successfully, assuming a complicated fault geometry estimated on the basis of the ...

Foreshocks of the 2016 MS5.1 Yunlong earthquake in Western Yunnan, China, and implications for earthquake nucleationKey points

Earthquake Science
Monitoring the evolution of foreshocks can be a valuable way to analyze the nucleation process. Foreshocks accompanying moderate mainshocks have been recorded in the west of Yunnan Province, China.

The Role of Disorder in Foreshock Activity

Geosciences
Foreshocks, observed before some large earthquakes, remain debated in terms of their origins and predictive value. While aftershocks fit well within bottom-up triggering models like ETAS, foreshocks may arise from distinct preparatory processes ...

Recognizing the waveform of a foreshock [PDF]

, 2020
Abstract The 2011 Mw9.1 Tohoku, Japan, earthquake is the paradigmatic example of an earthquake anticipated by a significant foreshock activity, with a Mw7.3 earthquake occurred two days before, within about 10 km 1. Recent results 2 show that statistically relevant changes can be found in the magnitude distribution after the Mw7.3 foreshock but

Foreshocks explained by cascades of triggered seismicity

, 2003
International audienceThe observation of foreshocks preceding large earthquakes and the suggestion that foreshocks have specific properties that may be used to distinguish them from other earthquakes have raised the hope that large earthquakes may be ...

Synchronization and desynchronization in the Olami-Feder-Christensen earthquake model and potential implications for real seismicity [PDF]

Nonlinear Processes in Geophysics, 2011
The Olami-Feder-Christensen model is probably the most studied model in the context of self-organized criticality and reproduces several statistical properties of real earthquakes.

Surface Consistent Seismic Hazard Assessment in the Shillong Plateau, Northeast India: A Probabilistic Approach Using Multiple Source Models and a Logic Tree Framework

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT We perform probabilistic seismic hazard analysis (PSHA) in the Shillong Plateau by clubbing the up‐to‐date earthquake data and seismotectonic properties of the study area. Twenty‐one areal seismic sources are delineated based on the updated earthquake catalog, tectonic, and fault plane solutions.

Analysis of short time-space range seismicity patterns in Italy

Annals of Geophysics, 1997
In our paper we analyze the data base obtained from the observations of the Italian Seismological Network from 1975 to 1994 by using a simple algotithm to determine the rate of occurrence of seismic events condi- tioned by the occurrence of previous ...

Wavelet‐Based Hurst Exponent Estimation

WIREs Computational Statistics, Volume 18, Issue 3, September 2026.
The review explores how wavelet‐based methods for estimating the Hurst parameters have developed from their theoretical roots to real‐world applications in fields like biology, engineering, and telecommunications. The review aims to highlight key techniques, compare their strengths and limitations, and point out challenges that still need to be ...
