Within eleven minutes on 11 August 2012, twin earthquakes measured 6.3 and 6.4 on the Richter scale jolted Ahar and Varzaqan in northwestern Iran, claiming 300 lives and leaving thousands of injured in rural villages.12 The magnitude of the earthquakes was so immense that more than a hundred villages were 70-90% destroyed, while 20 being totally flattened. The primary estimations were suggestiv...

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...

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 2012 Ahar-Varzegan earthquake and its aftershocks have not only caused huge damage with a severe loss of life and property but also induced many geo-hazards with the major type of collapse, creep, slip, debris flow, and fallings that are generally considered as landslide in this study which can cause continuous threats to the affected region. in this study, a semi-automated geo-hazard detec...
