A magnitude 6.1 earthquake, the strongest in nearly 150 years for the region, struck off Cuba's northwest coast on Monday. The US Geological Survey (USGS) reported the quake occurred at a shallow depth of 26 kilometers, with its epicenter located 104 kilometers west-northwest of Mantua, Cuba. This event was unusual for the Caribbean, as it happened within a tectonic plate, leading to scattered and less frequent seismic activity compared to plate boundaries. The earthquake was felt in parts of Cuba, Mexico, and Florida, areas not typically prone to such tremors.
