A 8.2-magnitude（震级）earthquake struck off the coast of northern Chile late on Tuesday, cutting power and leading to small landslides and a tsunami (海啸). Four men and one woman died —two who suffered heart attacks and three who were crushed（压死). About 300 prisoners escaped from the northern port city of Iquique in the immediate aftershock (余震).
The quake struck at about 8:46 p.m. local time, some 60 miles northwest of Iquique. It had a depth of 12.5 miles. Chile’s National Emergency Office asked coastal residents to leave for safe places. “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 on Wednesday. “The country has faced these first emergency hours very well.”
Residents in the port city of Antofagasta walked calmly through the streets to higher ground as traffic became heavy in some places. “Many people are fearful after experiencing the powerful earthquake in 2010, so they immediately rushed to higher ground when they heard the tsunami warning,” said a government official.”There have been lots of 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.”
The Pacific Tsunami Warning Center sent our several tsunami warnings, but called off all of them by early Wednesday.
Tsunami waves of more than six feet caused by the earthquake washed ashore on the coast of Pisagua. Iquique, with a population of more than 200,000, saw seven-foot waves.
