Head of the BMKG Earthquake and Tsunami Center Daryono, said that large earthquakes often occur on September 19 in Mexico. At least, he said, there were several large earthquakes in Mexico that occurred on September 19, namely the strong earthquakes of 1985, 2017, and 2022. The Puebla earthquake of September 19, 2017 with a magnitude of 7.1 killed more than 350 people, and caused damage in several Mexican states. .

The most popular destructive earthquake in Mexico was the 19 September 1985 Micchoacan Earthquake of magnitude 8.0 followed by an aftershock of Mag. 7.6 which caused the death toll of 9,500 people died.

As reported, this large earthquake also triggered sea waves up to a height of three meters or 9.8 feet and hit the Pacific coasts of Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Nicaragua, Panama, and Peru.

This earthquake was centered on land near Mexico's Pacific Coast. At least one person was reported dead and several buildings collapsed. The tsunami warning was originally issued immediately after the earthquake, but has since been revised. The Pacific Tsunami Warning Center said the tsunami threat had largely passed. Recent readings by the agency also show a decrease in wave height.

Daryono explained that the epicenter of the Mexico earthquake that occurred this morning appeared to be located close to a large earthquake of magnitude 7.6 in 1973 and 1941. Next, a powerful earthquake with a magnitude of 8.0 in 1985 that damaged the Michoacan region, and an earthquake of magnitude 7.5 in 2003.

Based on the history of earthquakes, he said, strong earthquakes are common occurrences along the Central American subduction zone. In the last 50 years alone, there have been 13 significant earthquakes with a magnitude of 6.5 or greater, within 250 km of the epicenter of the 7.6 magnitude earthquake this morning.

"The tectonic conditions on a wide scale from the Pacific Coast of Mexico are controlled by a plate collision system, which forms a subduction system of a plate subduction to the northeast from the Cocos Sea Plate, under the North American Plate at a plate subduction rate of about 70 mm/year," he explained.

Until this news was released, the local government was still collecting data on the damaged buildings and the possibility of additional deaths and injuries as a result of the earthquake. This earthquake also triggered a small tsunami at Manzanillo Beach, Colima.

"I thought I was going to have a heart attack!" said Gabriela Ramirez (58), one of the many residents across the city who rushed to the streets as quoted from France24, Tuesday (20/9/2022), which was broadcast by sindonews.com.

Mexican President Andres Manuel Lopez Obrador tweeted that one person was killed by falling debris in Manzanillo in the western state of Colima. "It is believed there was no serious damage in Mexico City," he said.

It was the third major earthquake on record to hit Mexico on September 19. Mexico City's early warning earthquake alarm went off, less than an hour after the capital held emergency drills as part of events to mark the 1985 and 2017 disasters.(mus/GOOGLE TRANSLATE)
