the tabriz fault in northwest of iran is the important geological structure in our country which historical earthquakes were recorded around it. the purpose of this paper is the study of tabriz fault seismotectonic activity. the method of research is drawing 23 cross section vertical to tabriz fault between tabriz and bostan-abad distinguish mountain-front faceting, mountain-front sinuosity and...

The North Tabriz Fault is seismologically an active fault with current right lateral strike-slip movements. Restricted mafic to intermediate Late Cretaceous igneous rocks are exposed along the North Tabriz Fault. Whole rock samples and clinopyroxene phenocrysts geochemistry were studied in order to characterize the petrogenesis of these mafic rocks and their possible relation to an oceanic crus...

introduction one of the important problems that most of the metropolitans encounter with is natural disasters. earthquake is a main natural disaster. annually 27 sever earthquakes are happened by nineteen thousands killed and twenty six homeless. in recent report of united nations planning office in 2003, iran has had the first position in number of earthquakes with severity higher than 5.5 ric...

basins leading to tabriz plain are part of the sub-basins of urmia lake basin, which is located in the east azerbaijan province and in the north-western part of iran. the area of this basin is 5397 km2, and agriculture is one of the main sources of income for the people, which is dependent on groundwater and surface water resources. in this study, an attempt was made to investigate the basins l...

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...

Abstract. The probabilistic fault displacement hazard analysis is one of the newest methods estimating amount in surface rupture areas. Considering strike-slip mechanism north Tabriz fault, Iran, using earthquake method and historical earthquakes 1721 1780, has been investigated, different scenarios estimated. fault's 50–60 km long section was selected as source possible from its data. Two were...

the investigation of this paper focuses on eastern part of shahroud fault system in middle-east alborz. this fault system is an important part in the seismotectonic map of the area. we used two local temporary dense seismological networks data installed around the fault system for several months during 2007 and 2008 and simultaneously micro-earthquakes data recorded by the permanent seismologic...
