Zhan et al. (2014a) reported supershear rupture during the Mw 6.7 aftershock of the 2013 Mw 8.3 Sea of Okhotsk deep earthquake, relying heavily on the regional station PET, which played a critical role in constraining the vertical rupture dimension and rupture speed. Here we include fivemore regional stations and find that the durations of the source time functions derived from these stations a...

Abstract Earthquake doublets have been described in fault systems around the world but not yet confidently resolved paleoseismic records. Our current knowledge is limited to historical occurrences, preventing researchers from uncovering potential patterns or recognizing common behavior. Identification of prehistoric thus crucial importance for adequate seismic hazard assessment and risk mitigat...

a doublet of earthquakes with magnitudes of 6.5 and 6.2 in mw scale (global cmt) on 2010 december 20 and 2011 january 27 respectively struck the area that lies between the nehbandan and jiroft fault systems, southeast of iran. these earthquakes occurred in correspondence of the southwestern termination of the kahourak right lateral strike slip fault. the focal mechanisms of both the mainshocks ...

We used continuous recordings in Sichuan, China to track the temporal change in elastic properties of the medium, namely the seismic speed, at a regional scale in a 2 year period which includes the great Wenchuan Mw 7.9 earthquake. The data are recorded by a temporary network of 156 broad-band seismographs, in a 200km × 200km region that covers the southern 2/3 of the fault system activated dur...

In 2012 August 11 (12:23 UTC) a moderate earthquake with MW=6.4 (USGS) occurred between Ahar and Varzaghan towns in Azarbayjan Province at northwest of Iran. After eleven minutes another earthquake shook the area with MW=6.2 (USGS). These consecutive earthquakes followed by intensive sequences of aftershocks whereas the strongest one had MW=5.3 (USGS). In data processing including depth modific...

the study area locates between an active fault system of north anatolian in turkey and active alborz and zagros mountain ranges in iran. the total shortening concluded from arabia-eurasia collision with a rate of 22 mm/year across the ne persia is partitioned  into  two  fault  systems,  right-lateral  strike slip  movements  in  the  turkish-iranian  plateau  like  north tabriz fault system an...
