This story has been updated with new developments. A magnitude 7.6 earthquake shook Mexico's central Pacific coast on Monday, killing at least one person and setting off a seismic alarm in the rattled capital on the anniversary of two earlier devastating quakes. There were at least some early reports of damage to buildings from the quake, which hit at 1:05pm local time, according to the US Geological Survey. It said the quake was centered 23 miles southeast of Aquila near the boundary of Colima and Michoacan states and at a depth of 9.4 miles.
President Andrés Manuel López Obrador said the secretary of the navy told him one person was killed in the port city of Manzanillo, Colima, when a wall at a mall collapsed, the AP reports. In Coalcoman, Michoacan, near the quake's epicenter, buildings were damaged, but there were no immediate reports of injuries. The US Tsunami Warning System said there was risk of a tsunami near the coast of Michoacan, the Guardian reports.
Alarms for the new quake came less than an hour after quake alarms warbled in a nationwide earthquake simulation drill marking major quakes that struck on the same date in 1985 and 2017. The magnitude 8.0 quake centered near the coast of Guerrero state in 1985 killed at least 9,500 people. More than 360 people died in the magnitude 7.1 quake that struck in 2017. "This is a coincidence" that it's the third Sept. 19 earthquake, said US Geological Survey seismologist Paul Earle. "There’s no physical reason or statistical bias toward earthquakes in any given month in Mexico." (More Mexico stories.)
