Macroseismic intensity map: this is how the 7.7 tremor felt in the country

The National Seismological Service reported that the magnitude 7.7 earthquake had greater intensity in the states of Michoacán, Colima and Jalisco, where it was recorded as strong.

In the extended report of the telluric movement at 1:05 p.m., it is reported that in neighboring entities it was felt as moderate and in Mexico City, State of Mexico and Morelos it was slight.

The magnitude 7.7 earthquake located near Coalcomán, in the state of Michoacán, occurred at 1:05:09 p.m.

This was recorded by broadband seismological stations, in which the largest earthquake and other small ones can be seen.

Seismological experts determined that the movement corresponds to a reverse type fault, in which the roof block rises with respect to the floor block. This type of rupture mechanism is frequent in interplate earthquakes and can potentially generate tsunamis.

The seismic activity in the state of Michoacán is intense. Historically, large earthquakes have occurred along the coast of this state as a result of the Cocos plate subducting beneath the North American plate.

Of great importance are the earthquakes of September 19 and 20, 1985 of magnitude 8.1 and 7.6, respectively, located at the interface between the Cocos and North American plates. These caused significant damage in a large area of ​​the center of the country and mainly Mexico City.

On April 11, 2012, a shallow magnitude 6.4 tremor occurred off the coast of the state of Michoacán. This earthquake gave rise to a swarm of 20 earthquakes between magnitudes 3.8 and 4.2 in the days following the main earthquake.

In the state of Michoacán there is constant seismic activity, in the last 10 years, the seismological has reported 11 seismic events with an epicenter located in the state of Michoacán and with a magnitude greater than 5.0.
