The 2011 Japanese tsunami was triggered by an underwater earthquake in March, 2011. The Japanese government believes that 5 million tons of wreckage was swept out-to-sea, with estimates reflecting 70% was sunk offshore. The remaining debris is floating in the Pacific Ocean. The first item to beach in Hawaii last September was a barnacle covered seafood storage bin. Livescience reports that the Hawaiian Islands are a hotspot for Pacific junk as wind acts on objects in similar ways. Once all of the tsunami debris was deposited, at the same time, some objects drifted faster than others. Scientists also report that the tsunami formed unexpectedly large underwater dunes that could influence Japan's ecosystem. Scanning the ocean floor to 50 feet, researchers found 65 foot long dunes that were six feet high.
