A shaking was registered in Union Hidalgo at 10:26 p.m. Central Time (4:26 UTC) this December 19, with a magnitude of 4.1 and a depth of 95.9 kilometers.
According to preliminary information from the National Seismological Service (SSN), the epicenter The earthquake was located 21 km southeast of the city, in the state of Oaxaca.
In the face of significant seismic activity, the National Center for Disaster Prevention (Cenapred)calls not to fall into rumors or false news and only obtain information from official sources, such as Civil Protection authorities, both local and state, as well as federal.
After an earthquake, check your house for possible damage, use your phone only in emergencies, do not light matches or candles until you are sure there is no gas leak, and remember that aftershocks of the earthquake may occur, so it is important to be alert.

During an earthquake, stay calm and stay in a safe place, stay away from objects that could fall; If you are in a vehicle, park and move away from buildings, trees and poles; And if you are located on the coast, stay away from the beach and take refuge in high areas.
Mexicans are accustomed to this type of events, since The country is located in an area of high seismicity. It is worth remembering the great damage caused by the earthquakes of 1985 and 2017, which caused great havoc throughout the Aztec territory. However, there are records of even more destructive movements in the country’s history.
The strongest earthquake recorded in the history of what is now Mexico had its epicenter in Oaxaca. That March 28, 1787trembled with the force of magnitude 8.6. Not only did the earth vibrate but the sea also showed its fury with a tsunami that went up to 6 kilometers beyond the coastline.
According to a study by the Center for Seismic Instrumentation and Registration (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 coming years. These will have the coasts of Mexico and Central America as their epicenter, as they are located in the Guerrero Gap that accumulates a large amount of energy.
However, a lower magnitude of 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.
On September 19, 1985, an earthquake of magnitude 8.2with epicenter in the state of Guerrero. It was 07:19 local time (13:19 UTC). At that time, it was thought that there would be no more earthquakes of such dimensions, but a similar event occurred exactly 32 years later.
The one in 2017 was recorded at 1:14 p.m. local time (6:30 p.m. UTC) with the epicenter on the borders of the states of Puebla and Morelos and left a balance of 369 deaths in the center of the country.
