Magnitude 5.0 earthquake strikes Puerto Rico amid ongoing aftershocks

A 5.0 magnitude earthquake hit southern Puerto Rico on Saturday afternoon, following a series of quakes and aftershocks that have rocked the island over the last few weeks.

The epicenter of the quake was about 10 miles south of Indios at a shallow depth of 8 miles, according to the U.S. Geological Survey.

More than 950 earthquakes and aftershocks have been recorded on Puerto Rico since Dec. 31, devastating infrastructure, causing power outages and water shortages and driving thousands of people to shelters. More than 4,000 people remained in shelters Saturday, and officials expected that number to rise, according to The Associated Press.

The worst quake – a magnitude 6.4 on Jan. 7 – killed at least one person and knocked out power to virtually the entire island of more than 3 million people. Days later, a magnitude 5.9 quake caused further damage and triggered a landslide in the southern municipality of Penuelas.

The island became embroiled in further turmoil last week when a Facebook video showed angry people breaking into a warehouse filled with unused emergency supplies dating from Hurricane Maria in 2017. The discovery particularly outraged those affected by the earthquakes, many of whom have struggled to find basic supplies.

Hundreds of people participated in a protest in San Juan on Thursday over the unused emergency aid. Later in the evening, police fired tear gas at a small group of protesters.

Earlier this month, President Donald Trump declared a "major disaster" in southern Puerto Rico and released billions of dollars in aid.
