A powerful earthquake measuring 5.8 on the Richter scale struck off the eastern coast of Cuba early on March 17, 2023. The earthquake's epicenter was near Guantánamo province, with a depth reported by international seismological organizations to be between 15 to 20 kilometers. The tremor was felt across many areas on the eastern side of the country, particularly affecting regions close to the epicenter. Reports indicated that local authorities had yet to confirm any damage or injuries following the quake.

The earthquake was recorded at a depth of 11.6 kilometers at 00:28 local time and the epicenter was located approximately 49 kilometers south-southwest of the easternmost municipality, Maisi, and 93 kilometers east of Guantánamo. This region of Cuba is known for its seismic activity, largely due to the proximity of tectonic plates in the Caribbean. The event raised concerns about the stability of this geologically active area, where earthquakes are not uncommon.

Following the main shock, several aftershocks occurred, with the strongest registered at a magnitude of 4.7. The presence of aftershocks often indicates further seismic activity and suggests that local authorities and residents should remain vigilant. While no significant damage has been reported so far, the situation continues to be monitored closely as seismic incidents can evolve rapidly, potentially leading to greater risks for the affected regions.
