A seismic swarm near Antigua has caught the attention of scientists and locals alike. Over the past three days, 19 earthquakes shook the waters near Antigua and Barbuda. This activity started on October 27 with a strong magnitude 6.7 quake far east-southeast of Saint John’s. The earthquakes happened at shallow depths beneath the ocean floor.

Since then, the region has seen many tremors, including some close to Antigua. Last night, a magnitude 3.9 earthquake struck just 52 kilometers north of Saint John’s. Two more quakes followed in the early morning hours, measuring 3.8 and 4.1. These recent events were farther offshore but still contributed to the swarm.

Most quakes happened between 220 and 280 kilometers from major towns like Point-à-Pitre, Guadeloupe, and Roseau, Dominica. The depths ranged mostly from 12 to 40 kilometers below the seafloor. This activity is being closely monitored by the University of the West Indies Seismic Research Centre.

The series of earthquakes shows how active the eastern Caribbean region can be. Scientists continue to watch for changes and possible impacts on nearby communities.
