Antigua and Barbuda has been struck by its 20th earthquake in less than a week, as a relentless series of tremors continues to unsettle the eastern Caribbean. The most recent quake, registering a magnitude of 4.0, occurred at 2:13 am local time, approximately 264 kilometers east-southeast of St. John’s, according to the University of the West Indies Seismic Research Centre (SRC). The quake originated at a depth of 10 kilometers. This seismic activity began on Monday, October 27, with a significant magnitude 6.7 earthquake, followed by numerous aftershocks, including magnitudes 6.1 and 5.4. The majority of these tremors have been concentrated offshore between Antigua and Barbuda, Guadeloupe, and Dominica. The SRC is actively monitoring the situation and has indicated that preliminary data for the latest quake may be subject to revision. The eastern Caribbean is situated on the boundary between the North American and Caribbean tectonic plates, making it one of the most seismically active regions in the area. Local authorities have advised residents to remain vigilant and adhere to guidance from disaster management officials.
