A magnitude 4.2 earthquake was noticeable in several municipalities of the Granma and Santiago de Cuba provinces shortly after six in the morning on Tuesday, according to a report on social media by Enrique Diego Arango Arias, Head of the National Seismological Service at the National Center for Seismological Research (CENAIS).
Arango Arias specified that the tremor occurred exactly at 6:11 a.m. and that it was perceptible "in several areas of Granma province and in the municipalities of Guamá and Santiago de Cuba."
The earthquake was located at the coordinates 19.75 degrees north latitude and 77.23 degrees west longitude, approximately 20.51 kilometers southwest of Pilón, in Granma, and at a depth of 10 kilometers.
"It was strong, and it happened quickly," wrote a user in the comments section who confirmed having experienced it.
Other residents in the area said they did not notice it but expressed concern about the increasing seismic activity in the region in recent days.
The CENAIS specified on its website that since the earthquakes of 6.0 and 6.7 magnitude on November 10, a total of 4,559 aftershocks have been recorded to date.
Of the total aftershocks, the entity specified that 106 have been "presumably perceptible"; and one, this morning, has been reported as "strongly felt at 6:11 local time, with a magnitude of 4.2."
In 2023, the National Center for Seismological Research reported a total of 7,475 earthquakes in the country, although only 14 were noticeable to the population.
The magnitudes of those events ranged from less than 3 to 5.9 degrees, with 70% of them concentrated along the Oriente fault.
This year, the most notable seismic activity occurred on November 10 in Granma, where two consecutive earthquakes with magnitudes of 6.0 and 6.7 were recorded.
Despite being classified as minor due to their short duration (the 6.7 magnitude earthquake lasted only seven seconds), they caused material damage and more than a dozen injuries.
