A 7.6-magnitude earthquake struck the South Atlantic Ocean on Friday, according to the US Geological Survey. Earthquake It prompted warnings about the possibility of a tsunami Along the coast of Chile on the western side of South America, but just over an hour later, authorities said dangerous waves were unlikely.
US National Tsunami Warning Centers in Alaska and Hawaii He said there was no tsunami risk To Hawaii, or to the East and Western coasts From Canada and the United States.
Agency data shows that the quake occurred at 4:29 p.m. Eastern time.
As seismologists review available data, they may revise the magnitude of the reported earthquake. Additional information collected about the quake may also prompt USGS scientists to update the tremor intensity map.
Aftershocks in the area
An aftershock is usually a smaller earthquake that follows a larger earthquake in the same general area. Aftershocks are usually minor adjustments along a portion of a fault that slipped at the time of the initial earthquake.
Earthquakes and aftershocks within 100 miles
Aftershocks can occur days, weeks, or even years after the first earthquake. These events can be equal to or larger in magnitude than the initial earthquake, and can continue to affect already damaged locations.
When earthquakes and aftershocks occurred

When aftershock data is available, the corresponding maps and graphs include earthquakes occurring within 100 miles and seven days of the initial quake. All times listed above are eastern. Vibration data as of Friday, October 10 at 4:47 PM ET. Aftershock data as of Friday, October 10 at 6:14 PM ET.
