NOTE: This has not been declared a FEMA Major Disaster.
An earthquake of magnitude 4.8 occurred after midnight on Tuesday 9 March 2021 at 12:43 am local time near Carolina, Carolina Barrio-Pueblo, Puerto Rico, as reported by the United States Geological Survey.
According to preliminary data, the quake was located at a very shallow depth of 8.8 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 Puebla (pop. 1,500) located 73 km from the epicenter, Charlotte Amalie (pop. 20,000) 77 km away, Fajardo (pop. 34,100) 82 km away, Loiza (pop. 4,300) 88 km away, and Road Town (pop. 8,400) 90 km away.
