Powerful Aftershock Rocks Chile a Day After Massive Earthquake

A massive aftershock struck northern Chile on Wednesday night, just a day after an earthquake prompted evacuations of cities along the coast, generated a 7-ft tsunami that crashed into the country’s northern coast, and set off tsunami warnings across the Pacific.

The Pacific Tsunami Warning Center posted a regional tsunami warning after Wednesday’s aftershock, but said there were no indications of a substantial threat to communities elsewhere in the Pacific.

Wednesday night’s 7.8 magnitude quake was the largest of myriad aftershocks in the past 24 hours and struck about 14 miles south of Iquique, setting off evacuations in northern Chile, where six people were killed by the quake on Tuesday.
