The temblor occurred at 1:18 a.m. Tonga time about 56 miles southeast of Pangai, Tonga, information from the usG.S reveals.
As seismologists assessment out there information, they could revise the earthquake’s reported magnitude. Further info collected concerning the earthquake may immediate U.S.G.S. scientists to replace the shake-severity map.
Aftershocks within the area
An aftershock is normally 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
Supply: United States Geological Survey | Notes: Shaking classes are based mostly on the Modified Mercalli Intensity scale. When aftershock information is on the market, the corresponding maps and charts embody earthquakes inside 100 miles and 7 days of the preliminary quake. All occasions above are Tonga time. Shake information is as of Monday, March 31 at 1:34 a.m. Tonga time. Aftershocks information is as of Monday, March 31 at 2:18 a.m. Tonga time.
