Two minor earthquakes happened within the area of 1 minute in Mexico City early Wednesday.
A 2.8 magnitude quake struck at 6:forty two a.M. And a 1.Eight magnitude one followed forty nine seconds later at 6:43 a.M., in line with the National Seismological Service (SSN).
Both micro-quakes had their epicenter three kilometers north of La Magdalena Contreras, the SSN stated. La Magdalena Contreras is a borough within the southwest of Mexico City. It is bordered to the north through the borough of Álvaro Obregón.
Residents of several boroughs felt the quakes, however they didn’t cause any harm, Mexico City authorities stated. Some residents stated they have been awoken with the aid of the shaking they triggered.
Mayor Martí Batrés stated in a television interview that the earthquake alarm didn’t burst off in Mexico City because the quakes have been handiest minor and had their epicenters in the capital.
The alarm “is activated earlier when the telluric wave comes from afar,” he said.
The alarm, amplified thru loudspeakers situated throughout the capital, sounds as much as a minute before a sufficiently effective earthquake begins to be felt, but it’s far dependent on sensors outside the capital. It can deliver citizens a brief window of opportunity to evacuate to the safety of the road and therefore keep away from the chance of being caught in a constructing that collapses.
In latest instances, there had been numerous minor earthquakes within the capital. A general of 23 had been recorded among Dec. 3 and Jan. 10.
Scientists have showed the presence of a kind of one-kilometer-long seismic fault under the ground of a densely populated place on the western facet of Mexico City.
Researchers from the National Autonomous University (UNAM) are investigating its relation to the common occurrence of micro-quakes in Mexico City.
