Tsunami-linked fishing boat adrift off B.C.

A Japanese fishing boat that waswashed out to sea in the March 2011 Japanese tsunami has been located adriftoff the coast of B.C., according to the federal Transport Ministry.

The 50-metre vessel was spotted by the crew of an aircraft on routine patrol about 275 kilometres off Haida Gwaii, formerly known as theQueen Charlotte Islands,ministry spokeswoman Sau Sau Liu said Friday.

"Close visual aerial inspection and hails to the ship indicate there is no one on board," Liu said. "The owner of the vessel has been contacted and made aware of its location."

U.S. senator Maria Cantwell, ofWashington, said in a release that the boat was expected to drift slowly southeast.

"On its current trajectory and speed, the vessel wouldn't make landfall for approximately 50 days," Cantwell said.

Cantwell did not specify where landfall was expected tobe.

First large debris

The boat is the first large piece of debris found following the earthquake and tsunami that struck Japan one year ago.

Scientists at the University of Hawaii say a field of about 18 million tonnes of debrisis slowly being carried by ocean currents toward North America.

The field is estimated to be about 3,200 kilometres long and 1,600 kilometres wide.

Scientists have estimated some of the debris would hit B.C. shores by 2014.

Some people on the west coast of Vancouver Island believe smaller pieces of debris have already washed ashore there.

The March 11, 2011, tsunami was generated after a magnitude 9.0 earthquake struck off the coast of northern Japan.

The huge waves and swells of the tsunami moved inland and then retreated back into the Pacific Ocean, carrying with them the wreckage of buildings, cars and boats.

Nearly 19,000 people were killed.
