Abstract

Dorouneh Fault System, as an active fault in Iranian Plateau, plays an important role in deformation and geomorphology of the region. This fault has caused some earthquakes in the 20th century. Detail study of Dourouneh fault's seismic characteristics indicates that in spite of Dorouneh Fault's high movement in Recent time, number of earthquakes and their magnitude is low that may be resultant of low slip rate, long recurrence interval and occurrence of creep on the fault. On the other hand, there are some witnesses that are indication of earthquake occurrence along Dourouneh fault which are accompanied with surface rupture.
