(NEXSTAR) – A tsunami advisory has been issued for parts of Alaska, California, Hawaii, Oregon and Washington after an undersea volcano erupted in the Tonga Islands.

The Pacific Tsunami Warning Center issued the tsunami Advisory for the Hawai‘i at 12:40 a.m. HST on Saturday, Jan. 15. PTWC said the situation is being monitored and the advisory will be canceled when the hazard has passed.

The state reported no major tsunami was expected to strike Hawai‘i. The state says the water displaced by the volcanic activity caused unusual sea level changes and alterations to typical sea currents starting at about 1:05 a.m. Saturday.

The volcano erupted on Friday, Jan. 14 at 6:27 p.m. HST.

The Pacific Tsunami Warning Center, also operated by the NOAA, had issued its own advisory for the state of Hawaii, warning that waves may be a hazard to swimmers, boaters, or anyone near the shore.

The state has partially activated the Emergency Operations Center at the Hawai‘i Emergency Management Agency (HI-EMA).

The National Tsunami Warning Center, a division of the National Oceanic and Atmospheric Administration (NOAA), added that “some impacts are expected” along the West Coast of the United States.
