Mount Suribachi (JPN.: , ''Suribachiyama'') is a 169 m high mountain at the southwest end of the island Iwo Jima (now officially Iō-tō) in the northwest Pacific Ocean, under the administration of Ogasawara Subprefecture, Tokyo Metropolis, Japan. The mountain's name derives from its shape, resembling a ''suribachi'' or "grinding bowl." It is also known as the "Mount Pipe" (JPN: パイプ山, ''paipu-yama''), since the sulfur gas and water vapor that rolls in from the summit, alongside the rest of the island, give the appearance of a smoking pipe when viewed from the sea. Joe Rosenthal's famous photograph ''Raising the Flag on Iwo Jima'' was taken at the mountain's peak. ==Geology== Geologically, the mountain is a cinder cone of andesite, formed by volcanic activity. It is thought that the mountain is a dormant vent to a still active volcano (designated Iō-tō, the name of the island as a whole). Most recently, the Japanese Meteorological Agency reported that on May 2, 2012, a small eruption caused water discoloration to the northeast, and confirmed the appearance of a new fumarole.〔 From 1889 to 1957, the Japanese government recorded 16 eruptions on the peak. This eruption lasted for 65 minutes, and created a crater with a diameter of 35 meters and a depth of 15 meters on the runway near the former World War II airfield. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mount Suribachi」の詳細全文を読む スポンサード リンク
