Shallow volcanic earthquakes in the Owakudani geothermal area, Hakone volcano, Japan
Earth, Planets and SpaceHakone volcano, located in central Japan, produced a small phreatic eruption in June 2015. Although seismic activity in the Hakone region is generally low, the area experiences episodic earthquake swarms approximately once every few years. In the volcano,

Harmonic tremor from the deep part of Hakone volcano
Earth, Planets and Space, 2022 The feeding system of magmatic fluid from the volcanic root to a shallow magma reservoir remains a poorly understood issue. Seismic events, including volcanic tremors and low-frequency earthquakes, in a deep part beneath volcanos are key observations for

Remote Sensing, 2020 Monitoring of surface displacement by satellite-based interferometric synthetic aperture radar (InSAR) analysis is an effective method for detecting land subsidence in areas where routes of leveling measurements are undeveloped, such as mountainous areas.

Geophysical Research Letters, 2021 Abstract From June 29 to July 1, 2015, a phreatic eruption occurred in Owakudani, the largest fumarole area in Hakone volcano, Japan. In this study, an interferometric synthetic aperture radar (InSAR) time series analysis of the Advanced Land Observing Satellite‐2 (ALOS‐2)/Phased Array type L‐band Synthetic Aperture Radar‐2 (PALSAR‐2) data was ...

Contribution of aseismic slips to earthquake swarms at the Hakone volcano
Earth, Planets and SpaceRecent studies have proposed the contribution of aseismic slip (AS) to earthquake swarms. We investigated the role of AS in earthquake swarms that occurred in 2009, 2015, and 2019 at the Hakone volcano, central Japan, through highly resolved hypocenter ...

Eastward Inclination of Hakone Volcano and Tanna Fault
Journal of Geography (Chigaku Zasshi), 2011 It is demonstrated that the eastern side of the Tanna fault has subsided relative to the western side using digital mesh data of geographic altitudes. The estimated subsidence is concordant with accumulated displacements of the Tanna fault and the fault slip at the 1930 Kita-Izu earthquake.

Futagoyama lava dome of Hakone volcano: an edifice formed by multiple eruptions
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.

Infrasonic wave accompanying a crack opening during the 2015 Hakone eruption
Earth, Planets and Space, 2018 To understand the initial process of the phreatic eruption of the Hakone volcano from June 29 to July 01, 2015, we analyzed infrasound data using the cross-correlation between infrasound and vertical ground velocity and compared the results of our ...

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 ...
