Seven earthquakes shook the western, central and southern parts of the Mexican capital, Mexico City, from Tuesday night (07/16/2019) until dawn on Wednesday (07-17 / 2019).
According to the National Seismological Service (SSN), between 10:59 p.m. from Tuesday (7/16/2019) until Wednesday morning at 1:04 (7/17/2019), there were 7 earthquakes between 2.2 and 3.0 with the epicenters in Mexico City.
These earthquakes are part of a seismic series that began on July 12 and added 15 movements with magnitudes between 2.1 and 3.0.
One of the earthquakes, in fact the largest of the serie, with a magnitude of 3.0 degrees, was nevertheless felt by millions of people, in which it generated fear and caused some to leave their homes.
The earthquake occurred at 10:59 p.m. in the center of Mexico, with the epicenter at a depth of only 3 km, at coordinates 19.41 °, -99.22 °, west of the areas of Álvaro Obregón and Miguel Hidalgo, along the Boulevard Los Virreyes, Lomas de Chapultepec .
It was reported that seismic vibrations were recorded in the mayoralties of Álvaro Obregón, Cuauhtémoc, Miguel Hidalgo, Benito Juárez and Cuajimalpa. There were no reports of damages or victims.
According to the application of earthquake warnings @SkyAlertMx (which registered it as 2.9 °), the fact that people have felt the movement, despite having been of relatively low magnitude, is due to the fact that the epicenter was very close, only 3 km deep and practically just below the houses.
Another factor to consider is that the soil, in most of Mexico City, consists of a mixture of mud and clay, which makes it susceptible to seismic shocks.
