The Quchan fault is located in Quchan - Shirvan area which is a part of Chenaran- Bojnourd plain in Kopeh-Dagh zone, NE Iran. The Quchan active fault with northwest – southeast trending is one of the most important strike-slip faults in the area which its activity led to the numerous historical and instrumental earthquakes. The Neo-tectonic activities of this fault are investigated by the drain...

in the last 150 year, most destructive earthquakes of kopeh dagh occurred near quchan. these earthquakes caused large damages to quchan (tchalenko, 1975; ambraseys and melville, 1982). the kopeh dagh zone accommodates a motion, by a combination of slip-partitioning in the nw, thrust faulting in the se, and anticlockwise block rotation in the central kopeh dagh (hollingsworth et al. 2006, 2008)....

but in some cases due to the inability forced the princes to rule some areas such as northern khorasan (which is a combination of social and population) to the heads of state and the khans and the tribes were deposited. so that quchan government (except for short) is always the beginning of the reign of the qajar dynasty zfranlvha and raza khan and their children and their amyrgvnh qlykhan boy ...

crustal velocity structure model has a significant role in truly understanding of seismicity and also in relocating earthquakes. on the other hand, it can be used for recognizing major and potential seismic sources which is very critical for seismicity and earthquake hazard assessment studies. seismic parameters simultaneous inversion modeling is one of the most prevalent methods in the study o...
