tsunami

Winter storms off the Oregon and Washington coastlines are expected to bring a new wave of debris from the 2011 tsunami in Japan. Scientists say objects are already washing ashore – with potentially invasive organisms riding along.

In March, 2011 an earthquake and tsunami devastated a large swath of eastern Japan. The tsunami reached heights of over 100 feet in some places, washing large quantities of manmade materials out to sea. Japanese officials estimate that about 1.5 million tons of debris floated out into the Pacific.

The Washington state education department has released a report detailing the natural disaster risks for schools across the state.

Along with familiar risks like earthquakes and wildfires, the list of natural disasters that threaten Washington schools includes things you may not have known to worry about.

In Auburn and Puyallup, it’s lahars – mud flows from volcanic eruptions.

The Woods Hole Oceanographic Institute announced Monday that trace amounts of radioactivity from Fukushima have been detected off the West Coast.

It's been exactly three years since a huge tsunami in March 2011 took thousands of lives in Japan and washed whole villages out to sea.

Following the 2011 tsunami in Japan, a nuclear reactor released hundreds of millions of gallons of radioactive water into the ocean. That sparked fear that contaminated water would reach the West Coast, but three years later, scientists say that radiation in our waters isn’t necessarily linked to the nuclear reactor. 

Washington and other Pacific Coast states set up tsunami debris reporting hotlines in the wake of the 2011 disaster in Japan.

SEATTLE - Building codes cover fire prevention, energy efficiency, and seismic safety among other things. Now a group of civil engineers from around the West is developing additions to the code to cover the threat of a tsunami.

Kent Yu of Degenkolb Engineers in Portland is one of the members of an American Society of Civil Engineers subcommittee drafting standards for "tsunami loads and effects."

"I think it is going to help make our communities more resilient."

A dock that washed ashore on a remote Washington beach last month is now confirmed as debris from the March 2011 tsunami in Japan. This news comes just as the federal government requests bids from salvage companies to get rid of the huge hulk.

State and federal biologists say they are confident they have minimized the invasive species threat posed by a derelict dock that washed ashore last month in Olympic National Park. The concrete and steel dock appears to have drifted across the Pacific Ocean after last year's tsunami in Japan. But the story is not over yet.

Scientists will soon head to the Olympic coast to evaluate a dock that washed ashore in a remote section of Olympic National Park. It could be debris from last year’s tsunami in Japan. It might even be as big as the gigantic piece of debris that showed up on Oregon’s coast in June. That dock weighed 188 tons.

Dave Workman with the Washington state Marine Debris Task Force tells KUOW’s Sara Lerner scientists need to see if invasive species might be hitching a ride on the dock. They also need to figure out how to remove it.

SALEM, Ore. – The state of Oregon is at odds with the federal government over how to use money from Japan meant for cleaning up tsunami debris. It can’t be used to reimburse the state for money it’s already spent.

The Japanese government donated $5 million to the US this fall to help pay for the cost of cleaning up debris from last year’s deadly tsunami. But Oregon hasn't seen a penny of that money so far.

LONG BEACH, Wash. – It’s been more than four months since the last confirmed piece of Japanese tsunami debris washed ashore on the Pacific Northwest coast. Even sightings of suspected disaster debris have tapered way off in recent months. Does that mean we’re just in a lull or past the worst of it?
