Properties of Foreshocks and Aftershocks of the Non-Conservative SOC Olami-Feder-Christensen Model: Triggered or Critical Earthquakes? [PDF]
, 2003 Following Hergarten and Neugebauer [2002] who discovered aftershock and foreshock sequences in the Olami-Feder-Christensen (OFC) discrete block-spring earthquake model, we investigate to what degree the simple toppling mechanism of this model is ...

Ion Acceleration Inside Foreshock Transients [PDF]
Journal of Geophysical Research: Space Physics, 2018 AbstractRecent observations upstream of Earth's bow shock have revealed that foreshock transients can not only accelerate solar wind ions by reflection at their upstream boundaries but may also accelerate ions inside them. Evidence for the latter comes from comparisons of ion spectra inside and outside the cores, and from evidence of leakage of ...

Is Earthquake Triggering Driven by Small Earthquakes? [PDF]
, 2002 Using a catalog of seismicity for Southern California, we measure how the number of triggered earthquakes increases with the earthquake magnitude. The trade-off between this relation and the distribution of earthquake magnitudes controls the relative ...

Extension of Gutenberg-Richter Distribution to Mw -1.3, No Lower Limit in Sight [PDF]
, 2009 With twelve years of seismic data from TauTona Gold Mine, South Africa, we show that mining-induced earthquakes follow the Gutenberg-Richter relation with no scale break down to the completeness level of the catalog, at moment magnitude MW −1.3.

Theory of Earthquake Recurrence Times [PDF]
, 2006 The statistics of recurrence times in broad areas have been reported to obey universal scaling laws, both for single homogeneous regions (Corral, 2003) and when averaged over multiple regions (Bak et al.,2002).

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.

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 ...
