Puerto Rico Governor Wanda Vazquez declared a state of emergency after the island got hit with a series of earthquakes. According to Reuters, at least one person was killed, several buildings fell over and power was knocked out. The strongest earthquake Puerto Rico faced was 6.4, the most powerful to hit the U.S. territory. Two large power plants were shut down, cutting off drinking water to at least 300,000 customers. Vazquez said she wasn’t sure when the power would be restored.
