Tsunami Advisory Issued for Hawai‘i Following Tonga Volcanic Eruption

For Immediate Release: Saturday, Jan. 15, 2022                    Release No. 2022-003

HONOLULU – The Pacific Tsunami Warning Center issued a Tsunami Advisory for the State of Hawai‘i at 12:40 a.m. HST on Saturday, Jan. 15, 2022, as a result of a volcanic eruption in Tonga.

Although no major tsunami was expected to strike Hawai‘i, 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 State Emergency Operations Center at the Hawai‘i Emergency Management Agency (HI-EMA) was partially activated to monitor the evolving situation. HI-EMA was coordinating state and county monitoring of the incident and efforts to alert people on beaches and state recreational shores who might be unaware of the unusual ocean conditions.

Swimmers and boaters, as well as people on shore in coastal areas are advised to use caution and be watchful for unusual sea activity, including shoreline flooding in low-lying areas.

The advisory was issued as a result of a large eruption at the Hunga-Tong-Hunga-Ha’apai volcano in Tonga at 6:27 p.m. HST on Friday that sent large waves onto the coast of Tonga.
