EFE (via 14ymedio), Havana, June 30, 2026 / A magnitude 3.9 earthquake was felt this past Tuesday in the municipality of Imías and other localities in the province of Guantánamo, in southeastern Cuba, reported the island’s National Center for Seismological Research
The seismic movement – the eighth perceptible one so far in 2026 – was reported at 9:22 a.m. and located 41 kilometers southeast of Imías, a coastal and mountainous municipality frequently noted for its seismic activity, according to the report based on data from the National Seismological Service. The Cenais bulletin indicates that, from June 28 through the early hours of June 29, four earthquakes were recorded in the Imías region with magnitudes ranging from 1.8 to 2.5.
This past June 8, a magnitude 6.2 earthquake with an epicenter in the Caribbean Sea shook Cuba’s western region, with no reports of personal injury or material damage so far. That tremor was felt throughout the entire western third of the island, from the provinces of Pinar del Río, Artemisa, La Habana, Mayabeque, and Matanzas, including the special municipality of Isla de la Juventud.
Seismic activity during 2025 recorded 4,535 seismic events in Cuba, of which 15 were perceptible.
According to Cenais specialist Enrique Arango, the area with the highest number of earthquakes last year was Pilón-Chivirico, with 1,849, the vast majority of them aftershocks of the magnitude 6.7 Pilón earthquake recorded on November 11, 2024.
The territory with the highest seismic activity in the country is the eastern region, specifically along the southern coast of the provinces of Santiago de Cuba, Granma, and Guantánamo. This high level of hazard is due to its proximity to the Oriente Fault, which marks the boundary between the North American and Caribbean tectonic plates.
Cuba is located in a region -stretching from the Dominican Republic to Mexico- where different tectonic fault systems converge, generating significant seismic activity.
