At 02:10 PM local time (UTC-5) on 28 January 2020, an earthquake with a magnitude of 7.7 Mw struck the north side of the Cayman Trough, north of Jamaica and west of the southern tip of Cuba, with the epicenter being 80 miles (130 km) east-southeast of Cayman Brac, Cayman Islands,[4] and 83 miles (134 km) north of Montego Bay, Jamaica.[5] Schools in Jamaica, as well as corporate and public buildings in Miami, were evacuated after shaking was experienced in parts of the U.S. state of Florida, a region not typically thought of in-relation to seismic activity.[6][7] Light shaking was also reported on the Yucatán Peninsula in Mexico.[8] The quake was the largest seismic event in the Caribbean since 1946.[9] A tsunami warning for the Caribbean Sea was initially issued by the Pacific Tsunami Warning Center, later being withdrawn.[10]
