American Samoa Lt. Gov. Aitofele Sunia has called on all residents on shorelines villages to move to higher grounds, while police in Samoa have issued a nationwide alert to begin coastal evacuations.
The tsunami is expected to reach the islands Saturday morning.
The American Samoa government has activated emergency services with off duty police officers and other first responders to report to their offices as soon as possible.
Meanwhile, disaster management officials in Fiji say they had been warned to expect waves of between as high as 7.5feet (2.3 meters) to hit the northern and eastern islands of the archipelago and the nearby Tonga islands.
On Sept. 29, a tsunami spawned by a magnitude-8.3 earthquake killed 34 people in American Samoa, 183 in Samoa and nine in Tonga. Scientists later said that wave was 46 feet (14 meters) high.
