A strong earthquake hit Mexico on Thursday, killing at least two people as residents rushed to the streets of the capital in the middle of the night after another strong earthquake.
A woman died in Mexico City after falling down some stairs and hitting her head when the earthquake triggered early warning alerts, while a second victim in the capital suffered a heart attack, authorities said.
The National Seismological Agency said the 6.9-magnitude quake’s epicenter was near the Pacific coast, 84 kilometers (52 miles) south of Colcumen in the western state of Michoacan.
The United States Geological Survey (USGS) estimated the volume at 6.8.
This was the strongest of more than 1,200 aftershocks from a 7.7-magnitude earthquake that struck the same area on Monday, the National Seismological Agency said.
The quake killed two people in western Mexico, damaged several thousand buildings and sparked panic more than 400 km away in Mexico City.
The latest quake sounded sirens again in the capital after 1:00 am (0600 GMT) and caused buildings to sway and sway.
Many people quickly evacuated their homes when the sirens sounded, and some were still wearing pajamas and carrying their pet dogs.
“We had a 6.9-magnitude aftershock and its epicenter was in Colcomman,” President Andres Manuel Lopez Obrador said on Twitter.
“Unfortunately, two people lost their lives in Mexico City,” he said, adding that there were no reports of casualties in the western states of Michoacan, Colima and Jalisco.
Mexico City Mayor Claudia Sheinbaum said official helicopters were flying over the capital and there were no initial reports of damage.
“So far there has been no damage to the city after the earthquake,” she wrote on Twitter.
The earthquake struck at a depth of 12 kilometers, according to the National Seismological Agency, while the US Geological Survey estimated the depth at about 24 kilometers, about 410 kilometers from Mexico City.
– Shocking memory –
Monday’s earthquake came less than an hour after millions of people in Mexico City participated in emergency drills in memory of two deadly earthquakes in 1985 and 2017.
The National Seismological Agency said the timing was no more than a coincidence.
“There is no scientific reason to explain this,” she added.
On September 19, 1985, an 8.1-magnitude earthquake killed more than 10,000 people and destroyed hundreds of buildings.
On the anniversary of the earthquake in 2017, a 7.1-magnitude earthquake killed about 370 people, most of them in the capital.
During Monday’s earthquake, a man was killed by falling debris in a shopping mall in Manzanillo, western Colima state.
A woman later died of injuries caused by a falling wall in the same city.
Mexico is located in the world’s most seismically active and volcanically active region, known as the Ring of Fire, where the Pacific Plate meets the surrounding tectonic plates.
Mexico City, which together with its surrounding urban areas has more than 20 million people, is built in a natural basin filled with the sediments of a former lake, making it particularly vulnerable to earthquakes.
The capital has an early warning system that uses seismic monitors intended to give residents enough time to evacuate buildings when earthquakes strike seismic areas near the Pacific coast.
