On June 8, 2026, a 6.1 magnitude earthquake struck near the town of Mantua in western Cuba, according to the United States Geological Survey (USGS). The quake occurred at a depth of 26 kilometers (16 miles) and was centered about 100 kilometers (62 miles) from Mantua, approximately 150 kilometers west of Havana.
The earthquake was felt across western Cuba, including in Havana, and tremors were reported in parts of southern Florida and Mexico's Yucatán Peninsula. No immediate reports of major damage or casualties were confirmed, though local authorities in Cuba urged residents to remain cautious and check for structural damage.
The USGS noted that this was one of the strongest earthquakes to hit Cuba in recent decades, though historical records indicate that a magnitude 7.0 earthquake struck the island in 1766. The 2026 event was shallow, which can amplify shaking near the epicenter.
Residents in the affected areas described feeling strong shaking for about 20 to 30 seconds. In Florida, the tremors were mild and did not cause any reported damage. Mexican authorities in the Yucatán also reported no significant impacts.
Seismologists continue to monitor the region for aftershocks. Cuba is located in a seismically active zone near the boundary between the North American and Caribbean tectonic plates, making it susceptible to earthquakes.
