In December 2017, three destructive earthquakes have occurred around Hojdek, in Kerman province. The earthquakes did not cause human loss but frightened the local people and produced extensive destruction in the epicentral area. In this study, moment tensor inversion in time domain is used to obtain the source mechanism of mainshocks. The results indicate that the mechanisms of earthquakes are mainly reverse and are in agreement with the trend of tectonic forces as well as the mechanisms of other earthquakes in the region. The moment tensor inversion for aftershocks indicate that the mechanisms of aftershocks were mainly reverse and were consistent with the mechanisms of mainshocks. The epicentral distribution of relocated aftershocks indicates two clusters. The spatial distributions of clusters are in agreement with the epicentral distribution of mainshocks. The cluster around the first earthquake in EW cross section has a length 15-20 Km, while the cluster around the second and third has a length about 20-25 Km.
