Futagoyama lava dome of Hakone volcano: an edifice formed by multiple eruptions
The Journal of the Geological Society of Japan, 2010 The Futagoyama lava dome, one of the post-caldera central cones of Hakone volcano (Kanagawa, Japan), is though to have formed by a single eruption at 5 ka. However, in this study, we show that the dome formed over the course of at least three eruptions.

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 ...

Geographical Features of the Hakonemachi Fault at the Bottom of Lake Ashi in the Hakone Volcano
Journal of Geography (Chigaku Zasshi), 2010 The bottom topography of lake Ashi-no-ko, in the Hakone volcano caldera, was examined using the SeaBat8101 narrow multi-beam sonar system. The purpose of micro-topographical observations of the lake bottom is to understand the tectonic relations between the historical formation-process of the caldera and the strike-slip motion in the Tanna-Hirayama ...
