Seismologists monitor aftershocks of the earthquake recorded in Santiago de Cuba.

The aftershocks, oriented south-north, have drawn attention for their similarity to the seismic swarm following the earthquake on January 17, 2016.

Following the registration this Thursday of a 5.1 magnitude earthquake on the Richter scale, approximately 20 kilometers south/southwest of the city of Santiago de Cuba, seismologists are keeping a close watch on the aftershocks associated with that seismic event.

These replicas are oriented south-north, which has drawn the attention of experts due to their similarity to the behavior of the seismic swarm following the earthquake of January 17, 2016, reported Enrique Diego Arango Arias, head of the National Seismological Service of Cuba, from the National Center for Seismological Research (CENAIS), via Facebook.

"The aftershocks have a south-north orientation, similar to the behavior of the swarm of earthquakes that began on January 17, 2016," the expert indicated, recalling a seismic event and the following days that kept the population in eastern Cuba, especially in Santiago de Cuba, on edge.

However, Arango emphasized that it is not possible to predict how this seismic activity will evolve, and he stressed that the team from the Central Station of the National Seismological Service will continue to monitor the area.

It also shared a map of the registered epicenters, available for public consultation on the CENAIS website.

The 5.1 magnitude earthquake recorded this Thursday at 10:49 a.m. becomes the 12th perceptible seismic event in Cuba so far in 2024. The previous one occurred on September 7, with a magnitude of 3.8 on the Richter scale.

In 2023, a total of 14 perceptible earthquakes were recorded in Cuba, most of which were located on the Oriente fault, the main seismic activity zone in the country and a tectonic plate boundary to the south of the eastern region.
