Mexico’s strongest quake in a century strikes off southern coast

strongest quake in a century strikes off southern coast

An earthquake described by Mexico’s president as the country’s strongest in a century has struck off the southern coast, killing at least 36 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.

      President Peña Nieto said about 50 million Mexicans would have felt the tremor and that the death toll might rise. His office said he would travel to Chiapas to survey the damage.

At least 25 people were killed in Mexico’s Oaxaca state, 17 of them in the town of Juchitán, officials said.

Another seven were reported killed in Chiapas and three more, including two children, died in Tabasco state. President Peña Nieto said more than 200 people had been injured.

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

Images showed collapsed buildings across Oaxaca. In Juchitán, the municipal palace and a number of other structures were destroyed or badly damaged.

        A hotel collapsed in the town of Matías Romero, Oaxaca state, but it is not clear if there were any casua (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.

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.

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 were reported in the capital and social media video showed lampposts and the famous Angel of Independence statue swaying violently.

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.”

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