More than 200,000 buildings and countless other debris were washed out into the Pacific as a result of the recent tsunami. That wreckage is now being pushed across the ocean by the currents of the North Pacific Gyre with the debris headed toward Washington, Oregon and California, before circulating back toward Hawaii.
The average drift rate is five to ten miles per day, so it will take at least a year before the first debris makes landfall. These same currents have brought us the Great Pacific Garbage Patch, which is now set to get much bigger.
