The 2003 Bam earthquake is due to the right-lateral movement and shortening between Lut block and central Iran. The seismicity of the Bam region increased after the 2003 earthquake and has continued to this day. Earthquakes that happened with magnitude bigger than 6 indicate movement between the Lut block and central Iran. Before the Bam earthquake, the Bam fault did not have significant seismicity, but after the Bam earthquake, there was high seismicity in the area and the seismic focus was on the northern and southern parts of the fault. This seismicity indicating that Bam's fault is active and has the potential for other major earthquakes. Although the rupture fault by the Bam earthquake of 5 January 2003 was in the range of 2–10 km depth, but according to studies on aftershocks and subsequent earthquakes, seismic activity of the Bam fault zone to the depths It extends for about 20 kilometers and large earthquakes of up to 20 kilometers are possible on this fault. But according to the results of this study, the northern and southern sections of the Bam Fault in the period after earthquake 2003/12/26 have had significant activity, and we have seen even deeper earthquakes than the Bam earthquake. The full length of the fault is active even in the depths of less than 8 km, which is capable of even larger earthquakes.
