Preliminary results of earthquake geology studies within the macroseismic zone of triple earthquakes on July ۲, ۲۰۲۲ Sayeh Khosh east of Bandar Lengeh (magnitudes ۶.۱, ۶.۱ and ۶.۳), South Iran

توضیحات

Within the central part of the Alpine-Himalayan orogenic belt, Iranian Plateau is actively squeezing between Arabian and Eurasian plates to the south and north, respectively. In response, several destructive moderate-strong seismic events occur in this active tectonic area. At the 2:02 (local time) in the morning on Saturday, July 2, 2022, three successive earthquakes were occurred in less than two hours in south of Iran. These quakes (with magnitudes of 6.1, 6.1 and 6.3) were affected a relatively sparsely populated area located in the east of Bandar Lengeh port in Hormozgan province. Based on official news, according to extensive structural damages, these quakes have been accompanied by at least 49 causalities (5 killed and 44 injured) and so many people became homeless by these events. The almost sparseness population of the macroseismic zones of the quakes and awareness of people (due to seismic swarm in the last weeks) are the important issues cause a few casualties during the events. In a general view, the geological features as well as the interferogram evidence of these earthquakes can be tracked along an almost concentrated zone on the epicenteral domain (between Berkeh seflein Village, to the west and Bandarkhamir Port, to the east).
