Tsunami advisory issued for Oregon and Washington coasts after underwater volcano erupts | Local News


An undersea volcanic eruption in the South Pacific Ocean has triggered tsunami advisories for the Oregon and Washington coasts.



The National Tsunami Warning Center issued a tsunami advisory for the Oregon and Washington coasts Saturday morning after a large underwater volcano erupted near a South Pacific island.

It happened around 8:30 p.m. Friday near Tonga, triggering tsunami warnings for the island and advisories for New Zealand, Oregon, Washington, Alaska and Hawaii.

NWS Portland says they are expecting 1-3 foot waves along the Oregon Coast Saturday morning. They urge people to avoid beaches and harbors until the advisory is lifted.

Here is the wave timing for the Oregon Coast, according to NWS:

  • Newport, OR – 8:30 a.m.
  • Long Beach, Washington – 8:35 a.m.
  • Seaside, Oregon – 8:45 a.m.

The NWS warns that the first wave may not be the highest. NWS meteorologist Colby Newman told FOX 12 that the high waves could last a few hours, and these waves are different — they’re more “energized” and powerful, Newman says.

Tsunami advisories and warnings are rare on the west coast. FOX 12 Chief Meteorologist Mark Nelsen said the last time we had a major tsunami was in 2011, when a major earthquake struck off the coast of Japan.

The National Tsunami Warning Center issued a tsunami advisory for the Oregon and Washington coasts Saturday morning after an undersea volcano erupted Friday night near the Tonga Islands.



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

There were no immediate reports of injuries or the extent of the damage as all internet connection with Tonga was lost around 6:40 p.m. local time, said Doug Madory, director of internet analytics for the company. Kentik network intelligence.

In Hawaii, the Pacific Tsunami Warning Center reported waves measuring half a meter (1.6 feet) at Nawiliwili, Kauai and 80 centimeters (2.7 feet) at Hanalei. The National Weather Service said there were reports of boats being pushed into docks, but the danger was diminishing.

“We are relieved that no damage was reported and only minor flooding on the islands,” the tsunami center said, describing the situation in Hawaii.

The volcano is located about 40 miles north of the capital, Nuku’alofa. In late 2014 and early 2015, a series of eruptions in the area created a new small island and disrupted international air travel to the Pacific archipelago for several days.
