An earthquake of magnitude 7.1, with an epicenter 11 kilometers southeast of Acapulco, shook several states of Mexico this Tuesday, exactly four years after the strongest earthquake, although not the most devastating, in almost 100 years in the Central American country.
This September 7, the governments of Juchitán and Tehuantepec held commemorative events for the fourth anniversary of the natural disaster that caused the death of 99 people (79 in Oaxaca, 16 in Chiapas and four in Tabasco). Regarding the wounded, the reported figures were 192 in Chiapas, 10 more in Tabasco and 698 in Oaxaca.
On September 7, 2017, at 11:49 p.m., seismographs detected a strong earthquake with an epicenter 133 kilometers southeast of Pijijiapan, Chiapas. With a magnitude of 8.1, it was the more attempt since June 3, 1932, when an 8.2 earthquake occurred between the coasts of Colima and Jalisco.
“The largest earthquake recorded instrumentally in the country occurred # UnDíaComoHoy in 2017. Of magnitude 8.2 and with an epicenter in the Gulf of Tehuantepec, it shook the south and center of Mexico,” wrote this Tuesday the National Autonomous University of Mexico (UNAM) on Twitter, where he published a video that compiled several shuddering videos of the moment in which the earthquake developed.
Four years after that September 7, the country trembled again. However, this time the consequences were not so devastating. So far, there are no signs of serious injuries and a fatality was registered. It is about an inhabitant of Coyuca de Benítez, who lost his life after being hit by a pole that fell due to the earthquake.
In addition, several areas were without power and there was damage to some structures and buildings.
Meanwhile, local journalists valued the effectiveness of the Mexican Seismic Alert System, a tool that is essential in a territory prone to such natural disasters.
The successful seismic alert system includes an alarm every approximately two blocks. After the loud identifying sound, the phrase “seismic alert” begins to be repeated over the loudspeakers. In this way, the inhabitants manage to realize the danger and already know how to proceed, since emergency drills are common to practice evacuations.
On April 11, the Command, Control, Computing, Communications and Citizen Contact Center of Mexico City had carried out a sound test to verify the effectiveness of the system, which distributes 12,825 speakers in the country’s capital alone.
