Areas of the eastern part of American Samoa's main island, Tutuila, have been without power since the early hours of this morning.
Crews from the American Samoa Power Authority are trying to isolate where the problem is and restore electricity but power still hasn't been restored.
ASPA's deputy director, Fonoti Perelini Perelini, says a protective fuse in Atu'u blew and this disconnected power on one of the three phases serving that part of the island.
The fuse has been replaced three or four times but keeps blowing out.
Crews have not had any luck locating exactly where the fault lies.
It's the first extended power outage the territory has experienced in a long time.
