Mexico 7.7 magnitude earthquake: earthquake drills just after the real earthquake came, two major earthquakes in history also this day

Comprehensive Associated Press, "The Guardian" reported that on September 19, local time, a 7.7 magnitude earthquake occurred in western Mexico, the epicenter of the area building collapse, resulting in at least one person dead. Experts predict that the earthquake may trigger a tsunami and flooding as secondary disasters.

Coincidentally, the date of this earthquake in Mexico was the anniversary of two major earthquakes in Mexico's history, and the real one came shortly after the drill issued a simulated earthquake warning.

At least one person died in the quake

A 7.7-magnitude earthquake reportedly struck western Mexico at 1:05 p.m. local time on Sept. 19. The U.S. Geological Survey reported that the earthquake occurred in the state of Michoacan, whose state capital Morelia is located between Mexico City and Guadalajara, Mexico's two largest cities.

The epicenter of the quake was located 37 kilometers (23 miles) southeast of Aquila, near the border of Colima and Michoacan states, at a depth of 15 kilometers (9.4 miles).

Mexican President Lopez tweeted that the navy minister told him that a wall in a shopping mall collapsed in the port city of Manzanillo, killing one person.

It coincided with the anniversary of two major earthquakes in history

According to reports, the earthquake coincided with the anniversary of two major earthquakes in Mexico's history.

At least 9,500 people in Mexico were killed in the 8.0 magnitude earthquake that struck off the coast of Guerrero state on Sept. 19, 1985. Mexico was hit by a 7.1 magnitude earthquake on Sept. 19, 2017, which killed more than 360 people.

Members of the rescue team were participating in the 1985 and 2017 earthquake commemorations in Mexico City on Sept. 19 local time, conducting an earthquake drill that sent simulated earthquake alerts across the country. However, less than an hour later, they issued an alert for a new earthquake, and this time it was a real one.

"The two previous earthquakes were on this date, and there's always something on the 19th." One citizen in Mexico City exclaimed, "The 19th was a terrible day."

The community of Rome, located hundreds of kilometers northeast of the epicenter, was partial without power. Residents clutching their pets stood in the streets, while tourists who were visiting the area were visibly disturbed

One citizen said earthquake sirens went off soon after a simulated Memorial Day alert, and he wasn't sure if it was real or not.

U.S. Geological Survey seismologist Paul Earle said that this is Mexico on the date of September 19, the third earthquake, but also just "a coincidence," he said, the earthquake and simulation exercises have nothing to do with the previous devastating earthquake in Taiwan

The coast around the epicenter may be a tsunami

In the city of Akerman, Michoacán, near the epicenter of the quake, damage to buildings was evident.

"The earthquake started slowly, then was very strong and continued until it started to ease." A 16-year-old girl said she had to run out of her house and wait with her neighbors because of the quake. As a result of the quake, cracks appeared in the walls of the hotel and some houses along the street, and parts of the exterior walls and roofs began to fall off.

"At the hotel, the roof of the parking lot rumbled to the ground, and cracks appeared in the walls of the second floor." The girl said the town's hospital was severely damaged.

Michoacán authorities said they have not received more information about major damage in the state, other than cracks and collapsed buildings in Akerman.

Mexico City issued a mandatory evacuation order, and the mayor said there have been no reports of damage to the capital so far.

Mexico's National Civil Defense Agency cautioned that coastal water level changes near the epicenter could be as high as 32 inches (82 centimeters), according to historical data on tsunamis in Mexico.

The U.S. Tsunami Warning Center said there was a risk of a tsunami off the coast of Michoacán after the quake, while videos posted by users on social media showed flooding already in the city of Manzanillo.
