Powerful earthquake strikes off Chile, triggers tsunami

A mighty 8.2-magnitude earthquake struck off the coast of northern Chile late Tuesday, triggering small landslides, sapping power and generating a tsunami.

Four men and one woman died -- two due to heart attacks and three crushed to death, said Interior Minister Rodrigo Penailillo.

About 300 prisoners escaped from the northern port city of Iquique in the immediate aftermath, he said.

The quake struck about 8:46 p.m. local time, some 60 miles northwest of Iquique. It had a depth of 12.5 miles, the U.S. Geological Survey said.

Chile's National Emergency Office asked everyone to evacuate the South American nation's coast. And residents complied.

"The fact is, we will know the extent of the damage as time goes by and when we inspect the areas in the light of day," Chile's President Michelle Bachelet said early Wednesday morning. "The country has faced these first emergency hours very well."

Residents in the port city of Antofagasta,calmly walked through the streets to higher ground as traffic piled up in some places.

"Many people are fearful after experiencing the powerful earthquake in 2010, so they immediately fled for higher ground when they heard the tsunami warning," said Fabrizio Guzman, World Vision emergency communications manager in Chile.

"There have been multiple aftershocks and communications have been cut off in many of the affected areas. So people are waiting in the dark hills not knowing what is to come, and hoping they will be able to return to their homes safely."

At one point, the Pacific Tsunami Warning Center issued several tsunami warnings. All of them, including for Chile and Peru, were canceled early Tuesday morning. All tsunami watches, which once extended as far north as Mexico's Pacific coast, were called off as well.

Tsunami waves of more than 6 feet generated by the earthquake washed ashore on the coast of Pisagua, according to Victor Sardino, with the center.

Iquique, with a population of more than 200,000, saw waves 7 feet high.

'No hazards' to U.S. coastline

The U.S. National Tsunami Warning Center worked Tuesday to determine the level of danger for Alaska, Washington, Oregon and California, as well as Canada's British Columbia.

Gerard Fryer, a geophysicist with the Pacific Tsunami Warning Center, told CNN there is "clearly not going to be any hazards to the coastline of North America."

The Pacific Tsunami Warning Center issued a tsunami warning for Hawaii, saying strong currents may pose a hazard to swimmers and boaters.
