Beaches on the West Coast are getting a regular dose of debris from the 2011 tsunami in Japan. The first few items were curiosities — a boat here, a soccer ball there — but as the litter accumulates, officials such as Washington Gov. Chris Gregoire have acknowledged the scale of the problem.
"We are in for a steady dribble of tsunami debris over the next few years, so any response by us must be well-planned — and it will be," she said.
Beyond the obvious problem of litter, officials are on the lookout for hidden dangers.
