Powerful aftershocks rattled northern Chile on Thursday, startling residents and emergency workers a day after a large earthquake killed two people and injured more than 100 in the mineral-rich region.

There were no immediate reports of fatalities, injuries or damages from the 6.2 magnitude and 6.8 magnitude aftershocks near the Pacific coast city of Antofagasta. Many other smaller tremors have hit since the 7.7 quake on Wednesday.

The strong aftershocks struck as President Michelle Bachelet traveled to Antofagasta, Chile’s mining capital, to visit the quake zone. She was to go to the small towns of Tocopilla and Maria Elena, where homes and large buildings collapsed.

“We have significant damages in Tocopilla and Maria Elena as well as in other smaller towns,” government spokesman Ricardo Lagos said of the two hardest-hit towns, adding that at least 15,000 people were homeless.

“People here are pretty afraid. There have been so many aftershocks that start with a big noise, a humming noise, and then the ground starts moving and people start to run away,” Paula Saez, an aid worker with World Vision International, said from Tocopilla, where two people were killed.

The U.S. Geological Survey, or USGS, originally reported the first big aftershock on Thursday as magnitude 6.5, but then revised it down to 6.2. Its preliminary reading on the second aftershock was magnitude 6.8.

Copper prices soaring
Wednesday’s large quake cut power to some of the world’s largest copper mines, forcing them to work on backup generators on Thursday.

Copper prices jumped Wednesday by more than 6 percent to $3.3040 a pound on the New York Mercantile Exchange’s COMEX division. That price backed off 4.11 percent in early trading Thursday.

Operations were resuming at Escondida, the world’s largest copper mine.

The earthquake Wednesday was felt in neighboring Peru and Bolivia, as well as the Chilean capital of Santiago.

Two people were killed and at least 115 injured in Tocopilla, 75 miles north of Antofagasta, where people were caught under the rubble from crumbling roofs and balconies and where two floors of a hospital collapsed.

Electricity, water and telecommunications were cut to the town and most residents spent Wednesday night outdoors, under cold desert skies.
