Strong 7.8 magnitude quake hits off northern Chile - USGS

(Reuters) - A strong 7.8 magnitude earthquake struck off northern Chile late on Wednesday, the U.S. Geological Survey said.

The quake, the largest of a series of aftershocks following a powerful and deadly 8.2 magnitude quake that hit a day earlier, was located 12 miles (19 km) south of the port of Iquique at a relatively shallow depth of 12.4 miles (20 km), the USGS said. It was earlier reported as a 7.4 magnitude quake.
