A significant, 7.4-magnitude earthquake struck within the South Atlantic Ocean on Friday, prompting an alert for a possible tsunami alongside components of the Chilean coast, in keeping with monitoring companies in the US.

U.S.G.S. knowledge earlier reported that the magnitude was 7.5.
As seismologists assessment accessible knowledge, they might revise the earthquake’s reported magnitude. Extra data collected concerning the earthquake can also immediate U.S.G.S. scientists to replace the shake-severity map.
Aftershocks within the area
An aftershock is often a smaller earthquake that follows a bigger one in the identical normal space. Aftershocks are usually minor changes alongside the portion of a fault that slipped on the time of the preliminary earthquake.
Quakes and aftershocks inside 100 miles
Aftershocks can happen days, weeks and even years after the primary earthquake. These occasions might be of equal or bigger magnitude to the preliminary earthquake, they usually can proceed to have an effect on already broken places.
When quakes and aftershocks occurred
Supply: United States Geological Survey | Notes: Shaking classes are based mostly on the Modified Mercalli Depth scale. When aftershock knowledge is out there, the corresponding maps and charts embody earthquakes inside 100 miles and 7 days of the preliminary quake. All occasions above are Jap. Shake knowledge is as of Friday, Might 2 at 9:16 a.m. Jap. Aftershocks knowledge is as of Friday, Might 2 at 10:44 a.m. Jap.
