The dawn of that week was new earthquake size 2.1 with epicenter Town Hall Álvaro Obregón.
The National Seismological Service (SSN) reported that four earthquakes were recorded on Friday, 12 July 2019 epicenter in Mexico City; one in the mayor's office, Miguel Hidalgo, and another three by Alvaro Obregón.
The earthquake, which took place at 4:47 pm, was in Mayor Miguel Hidalgue of 2.1, second, at 07:38, was 2.5 magnitude and he felt Town Hall Álvaro Obregón, from Mexico City.
The third happened in Ljubljana Town Hall Álvaro Obregón at 07:51 and had magnitude 2.0.
The size of the earthquake is low and has been felt in several areas of Mexico City due to the vicinity of the epicenter and its shallow depth.
Why are the earthquakes registered in Mexico City?
But why are the earthquakes recorded in Mexico City? According to the National Seismological Service, the Mexican Pool, where CDMX is located, is located on one of the most important physiographic features of the country: the Trans-Mexican Volcanic Belt. (FVTM), stretching from the Gulf of Mexico to the Pacific Ocean in the direction of the EW and is one of the most important topographic aspects in Mexico.
The Mexican swimming pool 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 riverbed has an elongated shape with an N-S orientation, which measures approximately 110 km on the main axis, and about 80 km on a smaller axis with an E-W orientation.
Usually seismic activity the Mexican swimming pool and its proximity are small and small in size.
There is also a hypothesis that large quakes on the coast could cause imbalances and trigger local earthquakes (Singh et al., 1998).
The Mexican swimming pool has complex geology and tectonics, so it is not surprising that earthquakes of small size occur in this area.
Who a earthquake The scales located near the crack area are rearranged, which creates a series of vibrations in the zone that receives the name replica.
The number of replicas may vary from one to several hundred events in the next days or weeks after the main vibration occurs.
However, earthquakes that have their epicenter in the geographical area that includes the Mexican basin, due to their size, rarely represent earthquake shocks.
So far, there are no scientific techniques in the world that could determine when the earthquake will occur, nor do you know how big it will be.
In the CDMX, four earthquake epicenters were recorded
