In past decades, many destructive earthquakes with surface ruptures caused heavy destruction and human loss in Kerman province and along the south west boundary of Lut block. Within 12 days, three earthquakes with magnitudes about 6 occurred in the study region. More than 800 aftershocks with magnitudes greater than 2.5 occurred during the first 40 days. The reverse mechanism of earthquakes obtained in this study is in agreement with the geological evidence and the type of faults in the region. The relocation of earthquakes and aftershocks indicates at least three different trends. There are several active faults in this region. It seems that the earthquakes with magnitude greater than 6 occurred along different adjacent faults. Thus, it is concluded that the occurrence of first earthquake with magnitude 6.2 has affected the sourounding faults and has caused the following two earthquakes with magnitudes 6 and 6.2. Regarding the seismicity background and the distribution of active faults in the region, The activity of faults and the occurrence of earthquakes in future is not out of expectation.
