After an undersea volcano eruption, the Oregon coast has been under tsunami warning; waves of 1-3 feet are expected

After a lowsea volcano erupted near Tonga's Pacific nation, the entire West Coast, including coastal Oregon, is under the sun.

Initial waves in Oregon and Washington are with a 1.2-foot wave seen at Port Orford and a 0.8-inch wave observed in Charleston.

The first wave may not be the largest, but later waves may be larger.

The agency expects tsunami tsunamis to continue for at least three hours after the first wave, according to authorities.

It remains unclear if any bigger tsunami waves will impact the Oregon and Washington coastline, but its best to assume they are possible until more data comes into to say otherwise, said the weather service's Portland office.

People should not go to the coast to watch the tsunami, according to the weather service.


Residents in Hawaii, Alaska, and along the West Coast were asked to move away from the coastline to higher ground and pay attention to specific instructions from their local emergency management staff, according to Dave Snider, the tsunami warning coordinator for the National Tsunami Warning Center in Palmer, Alaska.

We dont provide an advisory for this length of coastline as weve done Im not sure when the last time was but it really isnt an everyday experience, said the author. I hope that increases the importance and severity of the situation for our citizens.

Residents should expect long term tides and unusual currents, according to Snider. There may be some low areas that are inundated, such as marinas and harbors.

The important thing here is that the first wave may not be the largest, but we might see it play out for several hours, he said. Its like everything will stay below the warning level, but its difficult to predict because this is a volcanic eruption and were able to measure earthquake or seismic-driven sea waves.


In Hawaii, the Pacific Tsunami Warning Center reported waves slamming ashore from a foot in Nawiliwili, Kauai, to 2.7 feet in Hanalei.

We are relieved that there are no reports of damage and only minor flooding throughout the islands, the center said, describing the situation in Hawaii.

On Tonga, a video posted on social media showed large waves washing ashore in coastal areas, swirling around homes and buildings.

Residents of American Samoa were alerted of the tsunami warning by local broadcasters as well as church bells that rang territory-wide. An outdoor siren warning system was out of service. Those living along the shoreline quickly shifted to higher ground.

Authorities in the nearby islands of Fiji and Samoa issued warnings, advising people to avoid the shoreline owing to strong currents and dangerous waves. The Japan Meteorological Agency said there may be a slight swelling of the water along the Japanese coasts, although it was not expected to cause any damage.

A convoy of police and military personnel evacuated Tonga's King Tupou VI from his palace near the shore, according to the Islands Business news website.

The Hunga Tonga Hunga Haapai volcano has been revealed as the latest of a series of spectacular eruptions.

A Twitter user named Dr. Faka'iloatonga Taumoefolau posted a video showing waves crashing ashore.

Can literally hear the volcano eruption, sounds pretty violent, he wrote in a later post: Raining ash and tiny pebbles, darkness blanketing the sky.

Scientists observed significant explosions, thunder, and lightning near the volcano before it began erupting on Friday. Satellite images showed a 3-mile wide plume rising into the air to approximately 12 miles.

Authorities in New Zealand were alerted of storm surges as a result of the eruption.

According to the National Emergency Management Agency, some parts of New Zealand might expect strong and unusual currents and unpredictable surges on the shore following a large volcanic eruption.

The volcano is located about 40 miles north of Nukualofa, the capital. Several days ago, a series of eruptions in the area created a small new island and disrupted international travel to the Pacific archipelago.

Tonga is home to around 105 million people.

This report will be updated.
