Earthquake Aftermath: Residents across Antigua and Barbuda are recounting strong shaking after a powerful earthquake hit northeast of the islands Saturday morning. The University of the West Indies’ Seismic Research Centre says the quake was about 31 km deep, with a preliminary epicentre at 17.39°N, 61.18°W—roughly 80 km northeast. Impact So Far: There are no immediate reports of injuries or major damage, but people in multiple communities felt the tremor. Regional Reach: The shaking was also reported across much of the eastern Caribbean, including the British Virgin Islands, Dominica, St Martin, Sint Maarten, Guadeloupe, Martinique, Montserrat, St Lucia, Puerto Rico, St Kitts and Nevis, the U.S. Virgin Islands, Caribbean Netherlands, Saint Barthélemy, and Anguilla. Why It Happens: The eastern Caribbean sits near the boundary of the Caribbean and North American tectonic plates, so seismic activity is common.
