We propose a new physically-based “multifractal stress activation” model of earthquake interaction and triggering based on two simple ingredients: (i) a seismic rupture results from activated processes giving an exponential dependence on the local stress; (ii) the stress relaxation has a long memory. The combination of these two effects predicts in a rather general way that seismic decay rates ...

Abstract This study comprehensively investigates the source mechanisms associated with mainshock and aftershocks of Mw = 6.3 Yogyakarta earthquake which occurred on May 27, 2006. The process involved using moment tensor inversion to determine fault plane parameters joint were further applied understand spatial temporal slip distributions during earthquake. Moreover, coseismal distribution was o...

In the last few years, several mainshock–aftershock sequences have demonstrated their effects on structures; especially after occurrence of an earthquake with high magnitude, number aftershocks tends to increase. For this reason, studies been oriented estimate influence structural response, most them in terms peak or residual displacement; however, energy plays important role for long-duration ...

Despite previous observations that aftershocks lie preferentially along the fault planes of mainshocks, many branching models for earthquake occurrences do not directly incorporate information on the moment tensors of mainshocks in forecasting the spatial distribution of aftershocks, or do so in a very simplistic way using spatial kernels which have not been rigorously tested on earthquake data...

The present work reports the analysis of a possible relationship due to stress transfer between the two earthquakes that hit the province of Van, Eastern Turkey, on October 23, 2011 (Mw = 7.2) and on November 9, 2011 (Mw = 5.6). The surface displacement field of the mainshock has been obtained through a combined data set made up of differential interferograms from COSMO-SkyMed and ENVISAT satel...

In this paper we propose a tri-stage cluster identification model that is a combination of a simple single iteration di tance algorithm and an iterative K-means algorithm. In this study of earthquake seismicity, the model considers event location, time and magnitude information from earthquake catalog data to efficiently classify events as either background or mainshock and aftershock sequences...
