A major, 7.6-magnitude earthquake struck in the South Atlantic Ocean on Friday, according to the United States Geological Survey. The earthquake prompted alerts about potential tsunami along the coast of Chile on the western side of South America.
The U.S. National Tsunami Warning Centers in Alaska and Hawaii said there was no tsunami danger for Hawaii, or for the east and west coasts of Canada and the United States.
The temblor happened at 4:29 p.m. Eastern, data from the agency shows.
As seismologists review available data, they may revise the earthquake’s reported magnitude. Additional information collected about the earthquake may also prompt U.S.G.S. scientists to update the shake-severity map.

When aftershock data is available, the corresponding maps and charts include earthquakes within 100 miles and seven days of the initial quake. All times above are Eastern. Shake data is as of Friday, Oct. 10 at 4:47 p.m. Eastern. Aftershocks data is as of Friday, Oct. 10 at 5:30 p.m. Eastern.
