DUBAI, United Arab Emirates — A powerful earthquake struck close to Iran's only nuclear power station on Tuesday, killing at least 32 people and injuring 850 as it destroyed homes and devastated two small villages, Iranian media reported.
The 6.3 magnitude quake totally destroyed one village, a Red Crescent official told the Iranian Students' News Agency (ISNA), but the nearby Bushehr nuclear plant was undamaged, according to Iranian officials and the Russian company that built it.
Many houses in rural parts of the province are made of mud bricks, which have been known to crumble easily in quake-prone Iran.
"Based on the most recent figures on the impact of the earthquake, 32 people have been killed and 850 injured," said deputy governor of Bushehr province, Shahpour Rostami, Fars news agency reported.
Across the Gulf, offices in Qatar and Bahrain were evacuated after the quake, whose epicenter was 89 km (55 miles) southeast of the port of Bushehr, according to the U.S. Geological Survey. The early afternoon shock was also felt in financial hub Dubai.
The Russian company that built the nuclear power station, 18 kilometers (11 miles) south of Bushehr, said the plant was unaffected.
"Personnel continue to work in the normal regime and radiation levels are fully within the norm," Russian state news agency RIA quoted an official at Atomstroyexport as saying.
Iran informed the U.N.'s International Atomic Energy Agency that there was "no damage to the Bushehr Nuclear Power Plant and no radioactive release from the installation," an agency statement said, adding that it was not currently seeking additional information.
One Bushehr resident said the quake shook her home and the homes of her neighbors but they were not damaged.
"We could clearly feel the earthquake," Nikoo, who asked to be identified only by her first name, said. "The windows and chandeliers all shook."
While initial fears about nuclear fallout receded, nearer the epicenter the rescue efforts ramped up into the night in search of survivors and to feed and house hundreds of residents who were traumatized by at least 14 aftershocks.
A Red Crescent official told ISNA that 20 people had been saved by rescue teams searching through the rubble.
Reports in Iranian media spoke of landslides destroying buildings and crowds gathering in the town of Dashti from outlying areas in search of help. Military officials said army and police units had been deployed to maintain order.
Water and electricity lines were severed and communities stayed in the streets because of the threat from aftershocks.
In a statement, Iran's most powerful authority, Ayatollah Ali Khamenei, offered his condolences to the victims and urged authorities to extend all efforts to save lives and help the afflicted.
Tuesday's quake was much smaller than the 9.0 magnitude one that hit Japan two years ago, triggering a tsunami that destroyed back-up generators and disabled the Fukushima nuclear plant's cooling system. Three of the reactors melted down.
Iran is the only country operating a nuclear power plant that does not belong to the Convention on Nuclear Safety, negotiated after the 1986 nuclear disaster in Chernobyl which contaminated wide areas and forced about 160,000 Ukrainians from their homes.
Western officials and the United Nations have urged Iran to join the safety forum.
Tehran has repeatedly rejected safety concerns about Bushehr - built in a highly seismic area - that began operations in September 2011 after decades of delays.
Iran sits on major fault lines and has suffered several devastating earthquakes in recent years, including a 6.6 magnitude quake in 2003 which flattened the southeastern city of Bam and killed more than 25,000 people. In August more than 300 people were killed when two quakes struck the northwest.
A report published last week by U.S. think-tanks Carnegie Endowment and the Federation of American Scientists said that "ominously" the Bushehr reactor sits at the intersection of three tectonic plates.
"Iran's sole nuclear power plant is not at risk of a tsunami similar in size to the one that knocked out the electricity and emergency cooling systems at Fukushima. But, repeated warnings about the threat of earthquakes for the Bushehr nuclear plant appear to have fallen on deaf ears," the report said.
The quake happened on National Nuclear Technology Day when Iran's leaders celebrate the technological advances they say will reduce the country's reliance on fossil fuels, leaving more of its abundant oil for export.
Israel, Gulf Arab states and many Western countries fear Tehran is seeking a nuclear weapons capability and the Islamic Republic is under international sanctions aimed at forcing it to curb some of its atomic work.
Iran denies it wants nuclear arms and says its atomic work is for electricity generation and other peaceful uses.
