Up to 20 million tons of debris from Japans tsunami moving toward Hawaii Crew on Russian ship STS Pallada spotted the debris almost 2,000 miles from Japan, including a fishing boat from Researchers say up to 20 mn tons of debris from Japan's March 11 tsunami could reach U.S. West Coast in three years. Some 5 to 20 million tons of debris--furniture, fishing boats, refrigerators--sucked into the Pacific Ocean in the wake of Japan's March 11 earthquake and tsunami are moving rapidly across the Pacific. Researchers from the University of Hawaii tracking the wreckage estimate it could approach the U.S. West Coast in the next three years, the UK Daily Mail reports. "We have a rough estimate of 5 to 20 million tons of debris coming from Japan," University of Hawaii researcher Jan Hafner told Hawaii's ABC affiliate KITV. Crew members from the Russian training ship the STS Pallada "spotted the debris 2,000 miles from Japan," last month after passing the Midway islands, the Mail wrote. "They saw some pieces of furniture, some appliances, anything that can float, and they picked up a fishing boat," said Hafner. The boat was 20-feet long, and was painted with the word "Fukushima." "That's actually our first confirmed report of tsunami debris," Hafner told KITV.
