IQUIQUE, Chile (AP) -- The U.S. Geological Survey says a powerful 7.8-magnitude aftershock has rocked Chile's northern coast, which was hit by a powerful magnitude-8.2 earthquake Tuesday night.
It caused buildings to shake in the port of Iquique, which saw some damage from the big quake on Tuesday. There are no immediate reports of new damage or injuries.
The latest tremor came 45 minutes after a strong 6.4-magnitude aftershock shook the same area.
The stronger aftershock's epicenter was 14 miles (23 kilometers) south of Iquique. The USGS said the aftershock had a depth of 12 miles (20 kilometers).
SANTIAGO, Chile (AP) -- Officials in Chile are reporting damage from a magnitude-8.2 earthquake that struck tonight off the coast of northern Chile.
The powerful tremor set off a small tsunami and caused landslides.
In the city of Arica, the mayor reports some homes made of adobe were destroyed and there were minor injuries.
The quake shook modern buildings in nearby Peru and in Bolivia's high altitude capital of La Paz, which is 290 miles away from the quake's center. Evacuations were ordered in both coastal Chile and Peru.
There have already been at least 10 strong aftershocks, including a 6.2 tremor. A seismologist at the University of Chile says more aftershocks and even a larger quake can't be ruled out.
Chile is one of the world's most earthquake-prone countries. The strongest earthquake ever recorded happened in Chile -- a magnitude-9.5 tremor in 1960 that killed more than 5,000 people.
