An earthquake categorized as light was registered in Rio Grande at 00:49 local time (GMT + 00: 00), with a magnitude of 4.1 and a depth of 5 kilometers. Its epicenter was located 18 km northwest of the city.
The impact on human victims and material damage due to this earthquake remains to be established, given the recent nature of the event.
Mexicans are used to this type of event, since the country is located in an area of high seismicity. It is worth remembering the great impact of the earthquakes of 1985 and 2017, which caused great damage throughout the Aztec territory. However, there are records of even more destructive movements in the history of this Latin American nation.
The strongest earthquake recorded in the history of Mexico occurred on March 28, 1787, at the time of the Spanish colony. Its epicenter was in Oaxaca and had a magnitude of 8.6 on the Richter scale. Not only did this make the earth vibrate incredibly, it even triggered a tsunami that reached 6 kilometers inland.
In 2009, the Center for Seismic Instrumentation and Registration (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. The epicenter is believed to be located in the region between the Mexican and Central American coasts. It should be noted that the area, known as the Guerrero Gap, has geological antecedents that support this hypothesis.
Earthquakes like the one on this day bring to the memory of Mexicans the worst memories of 1985 and 2017, when all of Mexico City was paralyzed before the shocking consequences that each one left.
As for 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 on the Richter scale. Since then, it was believed that nothing like it would repeat itself, but, coincidentally, it happened again exactly 32 years later.
In 2017, it happened at 1:14 p.m. local time (18:30 GMT), with its epicenter in an area between the states of Puebla and Morelos. So, the fatalities reached 369 people.
