TEHERAN (AFP) - A series of strong earthquakes rocked southern Iran on Saturday (July 2), killing at least five people, injuring over 80 others and flattening dozens of buildings.

The quakes, including two of magnitude 6.0, struck west of the major port city of Bandar Abbas in Hormozgan province, the US Geological Survey said.

The first rattled an area north of the town of Dezhgan shortly after 2am (5.30am Singapore time), before a 5.7 tremor hit two hours later followed quickly by the second 6.0 magnitude quake, said the USGS.

Hormozgan governor Mehdi Dousti said five people were killed, as cited by the official news agency IRNA.

Dousti told state television that the village of Sayeh Khosh, close to the epicentre, had been completely destroyed.

“Eighty-four people were injured out of whom only 15 are still in hospital for treatment,” national emergency services spokesman Mojtaba Khaledi told state television.

The state broadcaster showed video footage of residential buildings reduced to rubble in Sayeh Khosh, which was plunged into darkness in a power outage.

Ambulances and other vehicles tried to navigate roads covered in debris as shocked residents took to the streets or tried to recover items from their flattened homes.

People also spent the night outdoors in the provincial capital Bandar Abbas, with a population of more than 500,000, located about 100km east of the epicentres, where long queues formed in front of gas stations, state media reported.

Interior Minister Ahmad Vahidi visited Hormozgan province and told state television that restoring water and electricity are among the government’s top priorities.

History of deadly quakes

Iran's Red Crescent Society said in the morning that search and rescue operations were nearly over.

"We are concentrating on housing the victims of the earthquake," Dousti told television, adding that half of Sayeh Khosh was destroyed.

Iran sits astride the boundaries of several major tectonic plates and experiences frequent seismic activity.

The Islamic republic's deadliest quake was a 7.4-magnitude tremor in 1990 that killed 40,000 people in the north, injured 300,000 and left half a million homeless.

In 2003, a 6.6-magnitude quake in southeastern Iran levelled the ancient mud-brick city of Bam and killed at least 31,000 people.

In November 2017, a 7.3-magnitude quake in Iran's western province of Kermanshah killed 620 people.

In December 2019 and January 2020, two earthquakes struck near Iran's Bushehr nuclear power plant.

Iran's Gulf Arab neighbours have raised concerns about the reliability of the country's sole nuclear power facility, which produces 1,000 megawatts of power, and the risk of radioactive leaks in case of a major earthquake.

In February 2020, a magnitude 5.7 earthquake in northwestern Iran killed nine people, including children, in neighbouring Turkey and injured dozens on both sides of the border.

One person was killed in November last year when Hormozgan province was hit by twin 6.4 and 6.3 magnitude quakes.
