According to the United States Geological Survey, a massive 7.6 magnitude earthquake struck in the South Atlantic on Friday. The earthquake triggered warnings of a possible tsunami along the coast of Chile on the western side of South America.
The US National Tsunami Warning Centers in Alaska and Hawaii said there was no risk of a tsunami for Hawaii, or for the East and West Coasts from Canada and the United States.
The quake struck at 4:29 p.m. Eastern time, agency data shows.
As seismologists review the available data, they may revise the reported magnitude of the earthquake. Additional information gathered about the earthquake could also prompt USGS scientists to update the shaking severity map.
