Complex networks of earthquakes and aftershocks [PDF]

, 2004
We invoke a metric to quantify the correlation between any two earthquakes. This provides a simple and straightforward alternative to using space-time windows to detect aftershock sequences and obviates the need to distinguish main shocks from ...

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.

Sub-critical and Super-critical Regimes in Epidemic Models of Earthquake Aftershocks [PDF]

, 2002
We present an analytical solution and numerical tests of the epidemic-type aftershock (ETAS) model for aftershocks, which describes foreshocks, aftershocks and mainshocks on the same footing.

Observations of a new foreshock region upstream of a foreshock bubble's shock [PDF]

Geophysical Research Letters, 2016
AbstractEarth's foreshock is a region within the solar wind upstream of Earth's bow shock filled with backstreaming solar wind particles reflected at the shock. Within this region, when the interplanetary field is approximately radial, foreshock bubbles (FBs) can be formed when the backstreaming particles interact with approaching discontinuities ...

Some characteristics of foreshocks and aftershocks of the 2022 ML6.8 Chihshang, Taiwan, earthquake sequence

Frontiers in Earth Science
Foreshocks and aftershocks occurred before and after the ML6.8 (Mw7.0) earthquake in eastern Taiwan on 18 September 2022. We explore the epicentral distribution and temporal variations for the mainshock, foreshocks, and aftershocks.

Non-resonant Alfv\'enic instability activated by high temperature of ion beams in compensated-current astrophysical plasmas

, 2018
Context: Compensated-current systems are established in response to hot ion beams in terrestrial foreshock regions, around supernova remnants, and in other space and astrophysical plasmas.

Stochastic Stick - Slip Model Linking Crustal Shear Strength and Earthquake Interevent Times [PDF]

, 2012
The current understanding of the earthquake interevent times distribution (ITD) is incomplete. The Weibull distribution is often used to model the earthquake ITD.

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 ...

Simulation study of the inhomogeneous Olami-Feder-Christensen model of earthquakes

, 2010
Statistical properties of the inhomogeneous version of the Olami-Feder-Christensen (OFC) model of earthquakes is investigated by numerical simulations. The spatial inhomogeneity is assumed to be dynamical.
