A magnitude 4.1 earthquake struck 21 km southeast of Esperanza on Wednesday morning, October 28, according to the U.S. Geological Survey (USGS). USGS timed it at 5:44 AM and puts the depth at 25 km. USGS did not flag a tsunami for this event.
The epicenter sits offshore, with Vieques the nearest town at 22 km, followed by Culebra at 40 km and Fajardo at 53 km. Five people had filed “Did You Feel It?” reports with USGS by the time of writing, 1.3 hours after the quake. No aftershocks had been recorded near the epicenter in that time.
This quake is far from the 2020 sequence that southwest residents remember. The epicenter is 156 km from Indios, Guayanilla, where the magnitude 6.4 earthquake of January 7, 2020 struck, the largest of that sequence.
