Mount Ontake
Mount Ontake, also referred to as Mount Kiso Ontake, is the 14th highest mountain and second highest volcano in Japan at.Description
Mt. Ontake is located around northeast of Nagoya, and around 200 km west of Tokyo, at the borders of Kiso and Ōtaki, Nagano Prefecture, and Gero, Gifu Prefecture. The volcano has five crater lakes, with Ni no Ike at being the highest mountain lake in Japan. Ontake is a major sacred mountain, and following older shamanistic practices, actors and artists have gone to the mountain to put themselves into trances in order to get divine inspiration for their creative activities.Eruptions
Ontake was thought to be inactive until October 1979, when it underwent a series of explosive phreatic eruptions which ejected 200,000 tons of ash, and had a volcanic explosivity index of 2. There were minor non-explosive phreatic eruptions in 1991 and 2007.
On Saturday, September 27, 2014, at around 11:53 a.m. Japan Standard Time, the volcano erupted with a VEI of 3. There were no significant earthquakes that might have warned authorities in the lead up to the phreatic eruption—caused by ground water flashing to steam in a hydrothermal explosion. The Mount Ontake volcano eruption was an extremely rare phenomenon which made it difficult to take precautionary measures. 63 people were killed; five bodies were never found. The Japan Self-Defense Forces began carrying out helicopter searches for missing people after the eruption.Gallery
