A very light earthquake shakes the city of Arriaga

The Center for Instrumentation and Seismic Recording of Mexico (Cires) reported a magnitude 3.9 tremor near Arriaga, being 05:17 local time (11:17 UTC). With a depth of 111 kilometers, it was perceived as very light by the local inhabitants.

Still there are no news regarding the victims and material damage that has caused this telluric movement.

It is worth noting that Mexico is at constant risk of experiencing a major earthquake, such as those that occurred in 1985 and 2017. Such movements caused various misfortunes. Despite being the most remembered, they have not been the largest in the territory.

The strongest earthquake on record In the history of Mexico, the March 28, 1787, at the time of the Spanish colony. Its epicenter was in Oaxaca and it had a magnitude of 8.6. This not only caused the earth to vibrate in an incredible way, but even caused a tsunami that reached 6 kilometers inland.

In 2009, the Center for Instrumentation and Seismic Recording (Cires) carried out a study to further investigate the events of 1787. It was then suggested that an event with a force greater than 8.6 degrees may occur soon. It is believed that the epicenter will be located in the region between the Mexican and Central American coasts. It should be noted that the area, known as the Guerrero Breccia, has geological antecedents that support this hypothesis.

But even smaller earthquakes can cause major damage. Examples of the above were the seismic events of 1985 and 2017. On those occasions, the life of the residents of Mexico City was disrupted, while both the Government and private citizens rebuilt buildings and infrastructure.

As for the one in 1985, it occurred on September 19 of that year at 7:19 local time (13:19 GMT), 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 one in 2017 occurred between the states of Puebla and Morelos at 1:14 p.m. local time (6:30 p.m. GMT). The balance of human victims reached 369 deaths.
