A 6.5 magnitude earthquake struck off the coast of Puerto Rico, knocking out electricity across the island. This earthquake comes less than one day after a 5.8 magnitude quake struck on Monday, damaging the coastal town of Guánica. The stone arch and natural landmark of Punta Ventana also collapsed when the earthquake hit. Today’s power outage comes after Puerto Rico experienced the longest blackout in U.S. history — and the second-longest blackout in world history — following devastating Hurricane Maria in 2017.
