“A massive dock” that was washed away from a city on Japan’s northeast coast by the devastating March 2011 tsunami landed this week on an Oregon beach. It’s a warning sign that dangerous chunks of debris from that disaster are reaching the Pacific coast of the mainland U.S. much sooner than predicted, The Oregonian reports.

Yonaguni underwater structure
“The Yonaguni Monument is a massive underwater rock formation off the coast of Yonaguni, the southernmost of the Ryukyu Islands, in Japan. There is a debate about whether the site is completely natural, is a natural site that has been modified, or is a manmade artifact. The site is variably referred to as the “Yonaguni Underwater Formations” (与那国島海底地形, Yonaguni-jima Kaitei Chikei?) and the “Yonaguni Underwater Ruins” (与那国島海底遺跡, Yonaguni-jima Kaitei Iseki?) in Japanese.” (from Wikipedia)
