A powerful earthquake hit the Pacific island nation of Vanuatu Tuesday, smashing buildings in the capital, Port Vila, including one housing the embassies of the U.S. and other nations. A witness told Agence France-Presse of bodies seen in the city.

Dan McGarry, a journalist with the Organized Crime and Corruption Reporting Project based in Vanuatu, told the Reuters news agency in an interview that police said at least one person had been killed and injured people had been taken to hospital.

“It was the most violent earthquake I’ve experienced in my 21 years living in Vanuatu and in the Pacific Islands. I’ve seen a lot of large earthquakes, never one like this,” he said.

The 7.3-magnitude quake struck at a depth of 35 miles, off the coast of Efate, Vanuatu’s main island, at 12:47 p.m. local time, according to the U.S. Geological Survey.

The ground floor of a building housing the U.S, French and other embassies had been crushed under higher floors, resident Michael Thompson told AFP by satellite phone after posting images of the destruction on social media.

“That no longer exists. It is just completely flat. The top three floors are still holding but they have dropped,” Thompson said.

“If there was anyone in there at the time, then they’re gone.”

Thompson said the ground floor housed the U.S. embassy, but that couldn’t be immediately confirmed.

A photo showed significant damage to the building:

The United States has closed the embassy until further notice, citing “considerable damage” to the mission, the U.S. embassy in Papua New Guinea said in a message on social media. “Our thoughts are with everyone affected by this earthquake,” the embassy said.

The New Zealand High Commission, housed in the same building, suffered “significant damage,” a statement from Foreign Minister Winston Peters’ office said, adding that, “New Zealand is deeply concerned about the significant earthquake in Vanuatu, and the damage it has caused.”

Thompson, who runs a zipline adventure business in Vanuatu, said, “There’s people in the buildings in town. There were bodies there when we walked past.”

A landslide on one road had covered a bus, he said, “so there’s obviously some deaths there.”

The quake also collapsed at least two bridges, and most mobile networks were cut off, Thompson said.

“They’re just cracking on with a rescue operation. The support we need from overseas is medical evacuation and skilled rescue, (the) kind(s) of people that can operate in earthquakes,” he said.

Video footage posted by Thompson and verified by AFP showed uniformed rescuers and emergency vehicles working on a building where an external roof had collapsed onto a number of parked cars and trucks.

The streets of the city were strewn with broken glass and other debris from damaged buildings, the footage showed.

Nibhay Nand, a Sydney-based pharmacist with businesses across the South Pacific, said he had spoken to staff in Port Vila who said most of the store there had been “destroyed” and that other buildings nearby had “collapsed.”

“We are waiting for everyone to get online to know how devastating and traumatic this will be,” Nand told AFP.

A tsunami warning was issued after the quake, with waves of up to three feet forecast for some areas of Vanuatu, but it was soon lifted by the Pacific Tsunami Warning Center.

Earthquakes are common in Vanuatu, a low-lying archipelago of 320,000 people that straddles the seismic Ring of Fire, an arc of intense tectonic activity that stretches through Southeast Asia and across the Pacific Basin.

Vanuatu is ranked as one of the countries most susceptible to natural disasters such as earthquakes, storm damage, flooding and tsunamis, according to the annual World Risk Report.
