Tremors in Mexico

It is worth noting that Mexico is at constant risk experiencing an earthquake of great magnitude, such as those that occurred in September of the years 1985 and 2017. Such movements caused misfortunes and, despite being the most remembered, have not been the largest in the country.

The On March 28, 1787, the strongest earthquake recorded in the country occurred.. Oaxaca, then the central point of the Spanish colony, was the victim of a move of 8.6. That event was so impetuous that it was followed by a tsunami that reached 6 kilometers inland.

According to a study by the Center for Instrumentation and Seismic Recording (Cires) carried out in 2009 on the earthquake of March 28, 1787, large earthquakes with magnitudes of 8.6 or greater could occur in the next few years. These will have as their epicenter the coasts of Mexico and Central America, as they are located in the Guerrero Gap, which accumulates a large amount of energy.

However, a lower magnitude in a seismic event does not necessarily translate into a lower impact on buildings and infrastructure. Thus, in 1985 and 2017, the inhabitants of the capital, Mexico City, had to face the devastation caused by two earthquakes that became a watershed in their lives.

As for the one in 1985, it occurred on September 19 of that year at 7:19 local time (13:19 UTC), with its epicenter in the state of Guerrero and a magnitude of 8.2. Since then, it was believed that nothing like it would be repeated, but, coincidentally, it happened again exactly 32 years later.

The 2017 one was recorded at 1:14 p.m. local time (6:30 p.m. UTC) with an epicenter on the borders of the states of Puebla and Morelos and left a balance of 369 deaths in the center of the country.
