A powerful 7.4 magnitude earthquake rattled the Mexican state of Oaxaca Tuesday morning and prompted tsunami warnings for Mexico and parts of Central America.

At least four people were killed.

The quake struck at 10:29 a.m. local time Tuesday about 7 miles southwest of Santa María Zapotitlán, on Mexico's Pacific Coast, according to the U.S. Geological Survey.

Federal civil defense authorities said a worker at the state-run oil company, Pemex, died when he fell from a refinery structure, The Associated Press reported. Another man was killed when a wall fell on him in the Oaxaca village of San Agustin Amatengo.

Mexico President Andrés Manuel López Obrador said one person was killed and another injured when a building collapsed in Huatulco, Oaxaca.

Oaxaca Gov. Alejandro Murat said a person was also killed in an apparent house collapse in the tiny mountain village of San Juan Ozolotepec.

Most reports were of minor damage such as broken windows and collapsed walls.

Murat said a hospital caring for COVID-19 patients suffered structural damage and had to be evacuated, according to Telemundo.

There were more than 140 aftershocks, most of them small.

Soon after the quake, the U.S. Pacific Tsunami Warning Center said tsunami waves of 3 to 9 feet above tide level were possible along Mexico's coast. Smaller waves were possible in other parts of Central and South America. No warning was issued for the United States.

Later in the afternoon, the warning center said the tsunami danger had passed and the largest wave measured was 2.3 feet.

In Huatulco, a coastal resort town, the earthquake knocked goods off shelves and some rubble from buildings, AP reported.

Mari González of the Princess Mayev hotel in Huatulco said staff and guests evacuates the building during the quake. Forty-five minutes later they were still outside as strong aftershocks continued.

“It was strong, very strong,” she said.

Local news media reported damage to some buildings in the state capital, Oaxaca city. State officials said they were looking for damage.

A journalist in Mexico City said the quake was felt there, nearly 500 miles away.

Power outages also were reported.

Pemex, Mexico's state-run oil company, said the quake caused a fire at its refinery in the city of Salina Cruz, relatively near the epicenter. It said one worker was injured and the flames were quickly extinguished.

This quake happened when the Cocos plate, which is to the southwest of the area, slipped under the North American plate, U.S. Geological Survey seismologist Paul Earle told AP.

“You’ve got all sorts of plates and they’re moving quickly,” Earle said. “The important thing is how fast the plates are moving relative to each other.”
