fault plane determination of the 2012 august 11 ahar-varzaghan earthquakes based on h-c method
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...
متن کاملAttenuation of Fourier spectra for 2012 Ahar–Varzaghan earthquakes, Northwestern Iran
In this research, we have used 102 strong motion recordings from 2012 Ahar-Varzaghan earthquakes (Mw=6.5 and Mw=6.3) to study the form of attenuation of shear wave Fourier amplitude spectra of those two events. The analysis is carried out in a broad-band frequency range from 0.1 to 20 Hz. A bilinear shape for geometrical spreading is assumed based on nonparametric regression of the data. The hi...
متن کاملSome Aspects about Seismology of 2012 August 11 Ahar-Vaezaghan (Azarbayjan, NW of Persia) Earthquakes Sequences
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...
متن کاملsimulation of the first earthquake august 11, 2012 ahar-varzaghan using stochastic finite fault method
on 11th of august 2012 the region was surprisingly struck by a shallow mw 6.4 (usgs) earthquake with pure right-lateral strike-slip character only about 50 km north of the north-tabriz fault. an east-west striking surface rupture of about 20 km length was observed in the field by geological survey of iran. only 11 minutes later and about 6 km further nw a second shallow event with mw 6.2 occurr...
