CDMX .- This afternoon, the capitalists were surprised by an almost imperceptible earthquake movement whose magnitude was 2.7 and which was located southwest of the delegation Benito Juárez ] reported on National Seismological Service.
Through social networks the head of government, José Ramón Amieva, reports that no damage was reported in the city .
The application SkyAlert noted that the movement could be perceived in the colonies Condesa, Narvarte, Roma Sur, San Pedro de los Pinos and Del Valle .
Up to 2018, six earthquakes were recorded with the epicenter in Mexico City compared to 2017, while there were 20 recorded since the aftershocks occurred in September. [19659002] This year the earthquakes took place with the epicenter in the Venustiano Carranza delegation, two were registered in the Álvaro Obregón delegation, one in Coyoacán, another in Miguel Hidalgo and the last on Saturday in the delegation Benito Juárez
Why earthquakes occur in CDMX?
According to the National Seismological Service (19459004), earthquakes are a normal situation because they are ground arrangements that are present after a major earthquake, which caused severe damage in September.
On September 7th, an 8.2 magnitude earthquake with epicenter in the Gulf of Tehuantepec, Chiapas, arrived in the metropolis a few minutes before midnight. As a result of them, activity in the central zone of the country has intensified, because seismological reported in this month 11 tremor with epicenter in Mexico City .
. September in the delegation of Tlalpan an earthquake of 2.6 intensity was provoked and the next day another telluric movement of 3.7, just in University City in the delegation Coyoacán .
Ten days later there were four other earthquakes in the capital that did not exceed 1.7 intensity, including three in the Tlalpan delegation: the first at 00:14 hours, second at 00:25, third at 03:03 at Cuajimalpa and 4:42 again at Tlalpan.
The earthquakes in the valley of Mexico are a normal phenomenon due to the tectonic faults that exist in the earth's crust, said Dr. Luis Quintanar, of SMN, who according to his statistics from the beginning of January to September 7, 2017, there were 14 earthquakes in the capital.
These earthquakes are a natural consequence after those experienced in the country on September 7 and 19, there are precedents that show that seismic activity is increasing in Mexico after earthquakes, as after the earthquakes. two years 1979 and 1985, Quintanar explained:
"There is an assumption that the energy released by the large earthquakes moves towards Mexico and deforms layers of the subsoil that are under This deformation gives rise to the triggering of these earthquakes, locally accelerates the processes of sinking by the type of soil of the capital " explained.
"A tremor is a movement of the ground, these waves can deform the subsoil in a sensible way and can cause subsidence in some places but also reactivate the faults that already exist" he said.
The energy that traveled from the shores of Chiapas and Oaxaca from the earthquakes were so important that they were concentrated in Coyoacán and Tlalpan, the two delegations where were born 12 of the 21 earthquakes of the last five months, "all the energy from the earthquake of September 19 this part, which could deform the layers of the earth's crust and cause these movements" .
