A powerful earthquake measuring 6.1 magnitude struck off the coast of western Cuba on Monday. The quake was felt widely across the island, prompting residents to evacuate homes and offices. Cuban authorities reported no immediate casualties or significant damage, while the US Geological Survey (USGS) noted the quake's epicenter was about 104 kilometers west-northwest of Mantua, Cuba, at a depth of approximately 26 km (16 miles) according to Indiatimes, Reuters, and SCMP.

This earthquake is notable as it marks one of the strongest tremors in the region’s history, with Paul Earle, a USGS seismologist, stating it was remarkably unusual for its occurrence within a tectonic plate. Residents in western Cuba described the experience as terrifying, with one local recalling, "It felt strong. I had never felt anything like that," highlighting the widespread alarm among those unaccustomed to such seismic activity according to Reuters and SCMP.

While no tsunami warning or watch was issued following the earthquake, emergency protocols were activated in both Mexico’s Yucatan and Quintana Roo states, where the tremor was felt in tourist areas including Cancun and Playa del Carmen. Local authorities indicated that there have been no reported damages in Mexico, maintaining an alert status until further assessments could be conducted according to Indiatimes, Reuters, and SCMP.
