Regional moment tensor inversion ofthe mainshock and
three aftershocks ofearthquake series in and around Qeshm island in
the Persian Gulf has been carried out using high quality broadband
data from Iran National Seismic Network (INSN). The events which
have been recorded at regional distances by stations of INSN have
started to jolt the island and the mainland Iran in two sequences
starting in November 2005 with a Mw=5.9 event and yet with another
series of events in June 2006 with a Mw=5.8 earthquake. The results
of the analysis for the main shock and three aftershocks from the two
above mentioned earthquake series are presented. From the focal
mechanism solutions, it appears that a mainly south-north trending
compressional axis prevails. Apart from a major aftershock in the
first earthquake series which shows the strike-slip mechanism with
small normal component of slip, the main shock and the other two
aftershocks show large component of reverse faulting along causative
faults trending NEE-SWW to SE-NW The horizontal components of
main compressional axes deduced from obtained solutions suggest
south-north directions which are in accordance with the expected axes
of shortening.
