A 6.1 magnitude earthquake struck western Cuba on Monday, prompting residents in Havana to evacuate buildings after feeling intense shaking for 20 seconds. According to the United States Geological Survey, the seismic event occurred approximately 100 kilometers from the island’s western tip. While the tremor was felt across western Cuba and parts of Florida, no victims or damages were reported.
How did the earthquake impact daily life in Cuba?
For many Cubans, the earthquake interrupted a day already defined by a severe energy crisis. According to reports from AFP, residents were forced into the streets as the ground shook, with some describing a disorienting experience. Carmel Delgado, a 47-year-old economist in Havana, told AFP, “At first I only felt dizzy; it didn’t occur to me that it was an earthquake, I had never experienced something like this.” Once the situation became clear, residents exited their buildings rapidly.
Why is Cuba facing a critical energy shortage?
The earthquake occurred against the backdrop of a deepening energy crisis that has gripped the island since mid-2024. Data from the state-run Unión Eléctrica (UNE) indicates that on the day of the tremor, 67% of the island faced simultaneous power outages. The Ministry of Energy and Mines (Minem) estimated a generation capacity of 1,035 megawatts (MW) against a peak demand of 3,050 MW, resulting in an estimated deficit of 2,045 MW.
The Cuban government has cited a “critical” situation regarding electricity, with some areas in Havana experiencing daily blackouts exceeding 22 hours.
What are the structural causes of the power deficit?
The current energy instability stems from two primary factors. First, a lack of fuel—which the Cuban government attributes to a United States oil blockade—has left power generation engines that rely on diesel and fuel oil largely idle. These engines typically account for 40% of the island’s power generation. Second, the nation’s thermoelectric plants, which provide another 40% of electricity, suffer from chronic underinvestment and extreme obsolescence, as many of these facilities have been in operation for decades.

Frequently Asked Questions
Was there a tsunami risk following the earthquake?
No. Authorities confirmed that there was no risk of a tsunami for the coastlines following the 6.1 magnitude tremor.
Where was the earthquake felt besides Cuba?
Reports from AFP confirm that the seismic movement was felt in parts of the U.S. state of Florida.
Are earthquakes common in this region?
While the island is located near the Oriente fault—which has generated destructive earthquakes in the past, including a 7.7 magnitude event in January 2020—seismic activity remains a periodic occurrence for the region.
