Light magnitude 4.6 earthquake 80 km northwest of Charlotte Amalie, U.S. Virgin Islands

4.6 quake 18 Nov 7:59 am (GMT -4)
An earthquake of magnitude 4.6 occurred only 7 minutes ago 80 km northwest of Charlotte Amalie, U.S. Virgin Islands, the United States Geological Survey (USGS) reported.
The quake hit at a shallow depth of 10 km beneath the epicenter in the morning on Wednesday 18 November 2020 at 7.59 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter. Weak shaking might have been felt in Charlotte Amalie (pop. 20,000) located 80 km from the epicenter, and Cruz Bay (pop. 2,700) 86 km away.
