American Geological Institute USGS revised the estimation for the earthquake magnitude produced in Samoa, from 7.9 to 8.0, while the Pacific Tsunami Center estimated the magnitude at 8.3 degrees.
According to CNN, the earthquake generated a tsunami of about 3 meters in the Pacific.
Authorities have issued alerts for American Samoa, Samoa, Cook Islands, Tonga and Fiji and warnings for areas located at greater distance from the epicenter, including Hawaii and Papua New Guinea.
The height of the wave was estimated at 7.5 meters, causing greatest damage and destroying many buildings in the coast area.

Authorities have estimated the seismic wave will not affect the U.S. coast and Canada.
