Crustal Movements Observed by the Tiltmeters during the 2015 Hakone Volcano Activity [PDF]
, 2017 Hakone volcano resumed a seismo-volcanic activity in April 2015. The activity led to a very small phreatic eruption on June 29 and 30. The Hot Springs Research Institute of Kanagawa Prefecture is operating a volcanic observation network composed of 7 ...

Tephrochronology and Eruptive Activity on Hakone Volcano in the Past 50ka.
The Quaternary Research (Daiyonki-Kenkyu), 1999 箱根火山周辺域に分布する箱根火山起源テフラ(降下軽石,火砕流堆積物)と富士火山起源テフラ,および広域テフラの層序関係を確立し,箱根火山中央火口丘の噴火活動史・火山体形成史を明らかにした.中央火口丘期の噴火活動は,新期カルデラ内に先神山(pre-Kamiyama)が形成されることにより始まった(約50ka).先神山の噴火活動は,最初,噴煙柱を形成しながら軽石を噴出していたが,徐々に軽石よりも類質岩片を多く噴出するようになり,最終的には先神山の一部が崩壊した(早川泥流CC2:約37,38ka).先神山崩壊後は,粘性の高い溶岩の大規模な流出に伴って,火砕流(block and ash flow)を頻繁に流下させながら溶岩ドームを形成する噴火様式に変化し,神山を中心とした中央火口丘群が次々と形成された ...

Coupled subdaily and multiweek cycles during the lava dome erupt of Soufriere Hills Volcano, Montserrat [PDF]
, 2013 Observations of volcanoes extruding andesitic lava to produce lava domes often reveal cyclic behaviour. At Soufriere Hills Volcano, Montserrat, cycles with sub-daily and multi-week periods have been recognised on many occasions.
