8.8-magnitude earthquake hits central Chile

SANTIAGO, Chile – A massive 8.8-magnitude earthquake struck Chile early Saturday, collapsing buildings, killing at least 16 people and downing phone lines. President Michele Bachelet declared a "state of catastrophe" in central Chile and said the death toll was rising.

Tsunami warnings were issued over a wide area, including Chile, Peru, Ecuador, Colombia, Panama, Costa Rica, Antarctica and Australia.

"We have had a huge earthquake, with some aftershocks," Bachelet said, appealing from an emergency response center for Chileans to remain calm. "Despite this, the system is functioning. People should remain calm. We're doing everything we can with all the forces we have. Any information we will share immediately."
