Early-Morning Earthquake Awakens Residents
A 6.4-magnitude earthquake shook Puerto Rico at 4:24 a.m. Tuesday, damaging buildings and causing a widespread power blackout. The earthquake was centered in the southwest part of the island, about 8 miles from Ponce, Puerto Rico’s second largest city. The quake was followed by a 6.0-magnitude aftershock about three hours later, along with a series of smaller aftershocks. No tsunami warnings were issued.
Puerto Rico’s Quakes Increasing in Frequency
Tuesday’s temblor occurred just one day after a 5.8-magnitude earthquake struck the southwest part of the country. Puerto Rico has experienced a high level of seismic activity along several fault lines in the southern part of the country in recent weeks, with more than 400 earthquakes of magnitude 2 or higher occurring since December 28, according to USGS.
