Eruptions
Script error: No such module "Labelled list hatnote". 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 (VEI) of 2.[3] There were minor non-explosive (VEI 0) phreatic eruptions in 1991 and 2007.[3]
On September 27, 2014, at around 11:53 a.m. Japan Standard Time (UTC +9),[4] the volcano erupted with a VEI of 3.[5][6] The eruption was phreatic—caused by groundwater flashing to steam in a hydrothermal explosion—and there were no significant earthquakes that might have warned authorities in the lead up to it.[7] The eruption was an extremely rare phenomenon, which made it difficult to take precautionary measures.[8][9] At the time of the eruption, several hiking parties were undertaking ascents and descents of Ontake, with emergency descents having to be undertaken in the presence of ash clouds and falling rocks.[10] 63 people were killed; five bodies were never found.[11]
