Cuba Hit by Offshore Earthquake After Nationwide Blackout as Officials Report Limited Impact

Seismic event follows island-wide power outage while officials monitor damage and regional conditions

An earthquake struck off the southeastern coast of Cuba early Tuesday, occurring less than a day after a widespread failure of the country’s electrical grid left the island without power.

According to Reuters, the European Mediterranean Seismological Centre recorded the quake at a magnitude of 6.0. The United States Geological Survey reported a slightly lower magnitude of 5.8, based on its own measurements available through USGS data.

A social media post from Reuters also noted the seismic activity, stating, “Magnitude 6 earthquake strikes Cuba, EMSC says,” as shown in this post.

Details reported by Business Standard indicate the quake occurred at approximately 12:28 a.m. local time at a depth of 11.6 kilometers, roughly 49 kilometers south-southwest of the port city of Maisí. The towns of Imías and San Antonio del Sur were identified as areas where moderate shaking may have been felt.

Authorities reported no immediate casualties or significant structural damage. The USGS classified the event with a green alert level, indicating a low likelihood of fatalities or major economic losses.

The earthquake followed a major infrastructure disruption on Monday when Cuba’s national power grid experienced a complete failure. According to a statement attributed to the U.S. Embassy, “At 1:54 p.m. local time, there was a disconnection of the national electrical grid resulting in a complete power outage across Cuba, which includes the Havana metropolitan area.”

The timing of the two events drew attention as officials continued to assess both the power outage and the seismic impact.

Separately, remarks by President Donald Trump regarding Cuba have circulated in recent days. In comments captured in this video clip, Trump said, “I do believe I’ll be…having the honour of taking Cuba,” while discussing the island’s current condition.

A prior statement shared in another clip referenced the possibility of a “friendly” U.S. takeover of Cuba.

Cuban authorities have not publicly linked the earthquake to the earlier power grid failure. Monitoring efforts remain ongoing as officials evaluate infrastructure stability and aftershock risks following the offshore quake.
