Thousands of people who evacuated Chile's low-lying coastal areas returned home Wednesday morning after authorities called off a tsunami alarm as damage from a massive overnight earthquake seemed mostly limited.
The major earthquake of magnitude 8.2 struck Tuesday night off the coast of northern Chile, killing six people and triggering a tsunami that pounded the shore with 6-foot waves.
Officials said the dead included people who were crushed by collapsing walls or were killed by heart attacks.
Mining in the world's No. 1 copper producer did not appear significantly interrupted.
Several metal-exporting ports in the Andean country remained closed on Wednesday morning following a tsunami evacuation, suggesting trade flows might be temporarily interrupted.
The copper price rose to its highest in more than three weeks on Wednesday on concerns supply could be affected. Chile supplies a third of the world's copper.
Early Wednesday Chilean authorities canceled their tsunami warning for most coastal areas. The Pacific Tsunami Warning Center said officials do not expect a major tsunami threat to Hawaii.
