A major earthquake just offshore rattled Chileans, killing five people and shaking the Earth so strongly the tremor was felt in places across South America.

Authorities worked on Thursday into assessing damage in several coastal towns that saw flooding from small tsunami waves set off by the quake.
The magnitude-8.3 quake hit off northern Chile on Wednesday night, causing buildings to sway in the capital of Santiago and prompting authorities to issue a tsunami warning for the Andean nation's entire Pacific coast.
People sought safety in the streets of inland cities, while others along the shore took to their cars to get to higher ground.
"Once again we must confront a powerful blow from nature," President Michelle Bachelet said in an address to the nation late Wednesday.
Authorities said early Thursday that five people had been killed and one person was listed as missing.

Bachelet urged people who evacuated from coastal areas to stay on high ground until authorities could fully evaluate the situation during the night. Officials said schools would be kept closed in most of the country Thursday.
Numerous aftershocks, including one at magnitude-7 and four above 6, shook the region after the initial earthquake” the strongest tremor since a powerful quake and tsunami killed hundreds in 2010 and leveled part of the city of Concepcion in south-central Chile.
Although officials cautioned it was too early to know for sure, it appeared Wednesday's quake had a much smaller impact than the 2010 tremor.
If that turns out to be the case, it will be a sign that
Chile's traditionally strong risk reduction measures and emergency planning had gotten better in the last five years.

"Earthquake impact is a little like real estate: what matters is location, location, location," said Susan Hough, a geophysicist with the US Geological Survey.
"But it is true that preparedness and risk reduction in Chile is ahead of that in much of the world, and that makes a difference."
The tremor was so strong that people in Buenos Aires, Argentina, on the other side of the continent, reported feeling it. People in Peru and Brazil also reported feeling the shakes.
No injuries were reported outside Chile. Claudio Moreno said he was in a Santiago bar when it hit. The shaking was powerful, but more worrisome was how long it lasted, he said.
"We went out in the street when we felt it was going on too long," he said. "It was more than a minute."
