A huge wave reached a populated area in the Robinson Crusoe Islands, 410 miles off the Chilean coast, said President Michele Bachelet. Tsunami warnings were issued over a wide area, including South America, Hawaii, Australia and New Zealand,
"It has been a devastating earthquake," Interior Minister Edmundo Perez Yoma told reporters.
Bachelet said the death toll was at 78 and rising, but officials had no information on the number of people injured. She declared a "state of catastrophe" in central Chile.
"We have had a huge earthquake, with some aftershocks," Bachelet said from an emergency response center. She urged Chileans not to panic.
"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," she said.
In the 2½ hours following the 90-second quake, the U.S. Geological Survey reported 11 aftershocks, five of them measuring 6.0 or above.
