A magnitude-5.8 earthquake has rocked northern Chile, the United States Geological Survey reported. There were no immediate reports of victims or major damage.
The Seismological Institute of the University of Chile says the quake hit at 12:12 a.m. Wednesday and was centered near the town of Pica, 1,120 miles north of Santiago. It was 21 miles deep.
The government's Emergency Bureau says it has received no immediate reports of victims or damage, but officials are seeking word from small Andean towns.
The quake hit 63 miles east of Iquique, near the country's large copper mining areas.
"Things are calm now after a quake which was felt intensely by the local population," Miriam Escobar, provincial governor of Iquique, told Reuters.
"There are some reports of landslides in the region, but no damage has been reported."
The USGS earlier measured the earthquake magnitude at 6.1, then revised the figure.
