Japanese dock washes up in U.S. state of Oregon

  • A huge portion of a dock torn off from a Japanese port by the 2011 tsunami has washed up 5,000 miles away on the coast of the western U.S. state of Oregon.

    The 165-ton structure made of concrete, metal and tyres landed on a beach south-west of the city of Portland.

    Police are guarding the dock while officials decide what to do with it. It has tested negative for radiation.

    It has taken 15 months for the 66-foot long structure to drift across the Pacific to Agate Beach.

    A plaque on the structure shows it came from the northern Japanese port of Misawa.

    Japanese scientists estimate that around 20 million tons of debris was generated by the earthquake and the tsunami, which killed nearly 16,000 people.
