An earthquake described by Mexico’s president as the country’s strongest in a century has struck off the southern coast, killing at least 33 people.

The quake, which President Enrique Peña Nieto said measured 8.2, struck in the Pacific, about 87km (54 miles) south-west of Pijijiapan.

Oaxaca and Chiapas states bore the brunt of the damage and dozens of aftershocks have been reported.

A tsunami warning was initially issued but later lifted.

The quake, which struck at 23:50 local time on Thursday (04:50 GMT Friday), was felt hundreds of miles away in Mexico City, with buildings swaying and people running into the street. The tremors there were reported to have lasted up to a minute.

President Peña Nieto said about 50 million Mexicans would have felt the tremor and that the death toll might rise.

Twenty-three people are reported dead in Mexico’s Oaxaca state, 17 of them in the town of Juchitán, state Governor Alejandro Murat said.

Another seven people were reported killed in Chiapas and two children died in Tabasco state, one a baby who died when power was cut to a respirator.

At least one person was killed in Guatemala, its president has said.

Social media images showed collapsed buildings in Oaxaca, including in the city of the same name, and in Juchitán, where the municipal palace and a number of other structures were destroyed or badly damaged.

A hotel in Juchitán is reported to have collapsed and people there are trapped in the rubble of their homes, officials said.

The Pacific Tsunami Warning Center (PTWC) had originally said that tsunami waves of more than 3m (9ft) were possible along the coasts of Mexico, with threats also facing El Salvador, Guatemala, Honduras and Costa Rica. It said later that waves only 0.7m high reached the Mexican coast.

Some coastal areas were evacuated as a precaution.


Panic on the streets

The earthquake has brought back memories of the tremor of 1985, which left massive destruction in Mexico City and a death toll of 10,000.

This explains the scenes of panic on the streets of the capital, more than 1,000km away from the epicentre. The government does not expect the same scale of physical destruction, as the states most affected are in the poorest and least-developed regions.

Chiapas is the southernmost state, along the Guatemalan border. It’s a very mountainous, remote area, where 25% of the population belong to indigenous groups. It’s also much visited by tourists seeking to explore some of the best and most well-preserved archaeological treasures, such as the ancient Mayan city of Palenque.


At magnitude 8.2, the quake outstrips the deadly 1985 tremor that hit close to Mexico City and caused thousands of deaths.

The US Geological Survey measured the latest quake slightly lower, at 8.1, saying it struck at a depth of 70km.

The tremor was strong enough to bring down buildings near Mexico City

More than a dozen aftershocks ranging from 4.3 to 5.7 in magnitude have been recorded closer to the Mexican coast.

Mr Peña Nieto warned there might be more.

He also said the Salina Cruz refinery on the southern coast had temporarily suspended operations.

Schools have been closed in 11 Mexican states.


Inevitable tremors

This is the biggest quake experienced anywhere in 2017. Going on the statistics, you would expect at least one magnitude 8 to occur somewhere on the planet each year.

It occurred where the Pacific ocean floor is drawn under Mexico and Guatemala. A great slab of rock, known as the Cocos tectonic plate, is driving towards the coast at a rate of 75mm per year. As it jerks downwards into the Earth’s interior, about 200km offshore, large tremors are the inevitable outcome.

There have been three magnitude 7s in 2017, with a 7.9 recorded deep under Papua New Guinea back in January. This latest event, being an 8.2, is nearly three times as energetic. That tells you something about how the magnitude scale works.

Fortunately, this event was deep, too. The rupture, which will have ripped across more than 100km of fault line, was down at 70km. That will have limited some of the shaking, but as we’ve seen there is still extensive damage.


Some electricity cuts have been reported in the capital and social media video showed lampposts and the famous Angel of Independence statue swaying violently, but there are no reports of major damage there.

Journalist Franc Contreras, who is in Mexico City, told the BBC: “You could hear loud cracks in the concrete. It sounded like a giant wooden branch being just broken open violently.

“People were streaming out of the hallways here. And everybody walking out single file into the streets, trying to avoid overhead high power lines.”

Guatemalan President Jimmy Morales appealed for calm on national television and in a Twitter post.

“We have reports of some damage and the death of one person, even though we still don’t have exact details,” Associated Press quoted Mr Morales as saying.

Cindy Lamothe, who is in the Guatemalan city of Antigua, told the BBC: “It was swaying so intensely it felt like we were in a boat and I heard neighbours screaming through the walls… it lasted almost three minutes.”

No tsunami warning has been issued for the US west coast.

Mexico is currently also being threatened on its eastern coast by Hurricane Katia.

The category one hurricane is about 300km south-east of Tampico and has sustained winds of 140km/h the National Hurricane Center says.
