2014 Mount Ontake eruption: characteristics of the phreatic eruption as inferred from aerial observations [PDF]
Earth, Planets and Space, 2016 The sudden eruption of Mount Ontake on September 27, 2014, led to a tragedy that caused more than 60 fatalities including missing persons. In order to mitigate the potential risks posed by similar volcano-related disasters, it is vital to have a clear understanding of the activity status and progression of eruptions.

Earth, Planets and Space, 2020 We present detailed maps of local-scale 3D deformation preceding the 2018 phreatic eruption at Iwo-yama volcano (south of Kyushu Island, Japan), using a combination of airborne and spaceborne Interferometric Synthetic Aperture Radar (InSAR) data.

Heat source of the 2014 phreatic eruption of Mount Ontake, Japan [PDF]
Bulletin of Volcanology, 2020 We present petrological evidence of the shallow magmatic processes that may have supplied heat and gas to the eruption of Mount Ontake, Japan, on 27 September 2014, which resulted in 63 fatalities. Ash from the eruption comprises primarily hydrothermally

Fluid flow of CO<sub>2</sub>-driven geyser activity as inferred from tilt and self-potential observations of the Kibedani Geyser Japan. [PDF]
Sci RepWe conducted multi-parameter, multi-site observations at the Kibedani Geyser, Japan, where cold spring-water eruptions (20 °C) are driven by underground CO2 pressure.

Sensitivity to lunar cycles prior to the 2007 eruption of Ruapehu volcano [PDF]
Scientific Reports, 2017 A long-standing question in Earth Science is the extent to which seismic and volcanic activity can be regulated by tidal stresses, a repeatable and predictable external excitation induced by the Moon-Sun gravitational force.

Anatomy of phreatic eruptions [PDF]
Earth, Planets and Space, 2018 This study investigates phreatic eruptions at two similar volcanoes, Kawah Ijen (Indonesia) and White Island (New Zealand). By carefully processing broadband seismic signals, we reveal seismic signatures and characteristics of these eruptions. At both volcanoes, the phreatic eruptions are initiated by a very-long-period (VLP) seismic event located at ...

Phreatic eruptions at Whakaari Volcano driven by hydrothermal mineralisation and magmatic gas input. [PDF]
Commun Earth EnvironPhreatic eruptions are a potentially lethal type of volcanic activity that is notoriously difficult to forecast. Understanding the complex processes that make eruptions more likely is a key step towards detecting precursory signals.

Migration of seismic activity associated with phreatic eruption at Merapi volcano, Indonesia [PDF]
Journal of Volcanology and Geothermal Research, 2020 Phreatic activity of Merapi started after nearly 2 years of quiescence following the October–November 2010 eruption which was the largest in more than 100 years. A dozen eruptions identified by visual and/or seismic observations took place between August

Earth, Planets and Space, 2018 In association with the September 2014 phreatic eruption (VEI 1–2) at Ontake Volcano, a syn-eruptive and two post-eruptive lahars occurred in the Akagawa–Nigorigawa River, southern flank of the volcano.
