The dawn of this week is new earthquake magnitude 2.1 with epicenter Álvaro Obregón City Hall.
The National Seismological Service (SSN) reported that on Thursday, July 12, 2019, four earthquakes were recorded epicenter in Mexico City; one in the office of mayor Miguel Hidalg and another three by Alvaro Obregón.
The earthquake, occurred at 4:47 am was the magnitude 2.1 in Mayor Miguel Hidalgo, the second, at 7:38 am, was magnitude 2.5 and he felt Álvaro Obregón City Hall, from Mexico City.
The third also happened in Álvaro Obregón City Hall at 07:51 and had magnitude 2.0.
Earthquake sizes are low and have been felt in several parts of Mexico City due to the proximity of the epicenter and its shallow depths.
Why are earthquakes registered in Mexico City?
But, since earthquakes were recorded in Mexico City, according to the National Seismological Service, the Mexican Pool where CDMX is located is on one of the most important physiographic features of the country: Trans-Mexican Volcanic Belt. (FVTM), stretching from the Gulf of Mexico to the Pacific Ocean in the direction of EW and one of the most important topographic slopes in Mexico.
Basin Mexico is located in the central part of the FVTM and is completely surrounded by mountains dominated by the most important volcanic buildings such as Popocatépetl (currently active), Iztaccihuatl, Ajusco and the state of Mexico, Nevado Toluca.
The pool is an elongated shape with an N-S orientation of about 110 km in its main axis, while on its smaller axis, with an E-W orientation, it measures about 80 km.
Usually seismic activity The Mexican swimming pool and its proximity are small and small in size.
There is also a hypothesis that large earthquake incursions on the coast could lead to imbalances and encourage local earthquakes (Singh et al., 1998).
The Basin of Mexico has complex geology and tectonics, so it does not surprise the occurrence of a small earthquake in that area.
When is a earthquake Significant rock sizes located near the rupture zone are subject to reorganization, which generates a series of tremors in a zone that gets its name replicas.
The number of replicas may vary from several to several hundred events in the coming days or weeks after the main shake has occurred.
However, earthquakes that have their epicenter in the geographical area that includes the Mexican Pool, due to their size, rarely present earthquakes.
To date, there are no scientific techniques in the world that could determine when an earthquake would occur, nor can you know how much it will be.
