'I didn’t think we'd get out': 6.4 magnitude earthquake leaves 1 dead, power out across Puerto Rico
An aftershock three hours later registered at magnitude 6.0. The temblors came one day after the island was shaken by a 5.8 magnitude quake that crumbled homes and triggered states of emergency across the island.
Tuesday's quake was the largest in a series that have struck the U.S. territory in recent days and caused heavy damage in some areas, forcing more than 300 Puerto Ricans to leave their homes and seek refuge.
