After an undersea volcano in the Tonga Islands erupted, a tsunami warning was issued for parts of Alaska, California, Hawaii, Oregon, and Washington.
As reported by the National Tsunami Warning Center, which is an agency of the National Oceanic and Atmospheric Administration (NOAA), “some consequences are predicted” along the West Coast of the United States.
Earlier, the Pacific Tsunami Warning Center, which is also maintained by the NOAA, had issued its own advisory for the state of Hawaii, warning that waves may pose a hazard to swimmers and boaters, as well as anyone who is near the shoreline.
For more specific information, consult the National Tsunami Warning Center’s advisory for the following areas:
- From the California/Mexico border to the Oregon/California border, including San Francisco Bay, is considered to be part of the Pacific Ocean.
- The Oregon coast stretches from the California/Oregon border to the Washington/Oregon border and includes the Columbia River estuary coast.
- The outer coast of Washington, from the Oregon/Washington boundary to Slip Point, as well as the Columbia River estuary coast and the Juan de Fuca Strait coast, are all protected by federal law.
- From the north coast and Haida Gwaii through the central coast and northeast Vancouver Island, the outer west coast of Vancouver Island, and the coast of the Juan de Fuca Strait, British Columbia has a diverse range of landscapes.
- Southeast Alaska includes the inner and outer coasts from the British Columbia/Alaska border to Cape Fairweather, as well as the interior of the state.
- In South Alaska and the Alaska Peninsula, includes the Pacific beaches from Cape Fairweather to Unimak Pass, as well as the interior of the state of Alaska
- The Aleutian Islands, from Unimak Pass to Attu, and the Pribilof Islands are included.

As early as 6 a.m. in some parts of Alaska, 7:35 a.m. in some parts of California, 7:55 a.m. in some parts of Oregon, 8:30 a.m. in some parts of British Columbia, and 8:35 a.m. in some sections of Washington, tsunami activity was projected to begin.
The tsunami, which was produced by an undersea volcano approximately 40 miles from Tonga’s capital and visible from space, sent waves slamming across the country’s shorelines, according to reports from the Associated Press on Saturday. There were no reports of injuries at the time of publication.
