On the occurrence of phreatic eruptions at Ruapehu: statistics and probabilistic hazard forecast for ballistics [PDF]
Journal of Applied Volcanology, 2017 Phreatic eruptions, although posing a serious threat to people in crater proximity, are often underestimated and have been comparatively understudied. The detailed eruption catalogue for Ruapehu Volcano (New Zealand) provides an exceptional opportunity ...

Short-period volcanic gas precursors to phreatic eruptions: Insights from Poás Volcano, Costa Rica
Earth and Planetary Science Letters, 2016 Volcanic eruptions involving interaction with water are amongst the most violent and unpredictable geologic phenomena on Earth. Phreatic eruptions are exceptionally difficult to forecast by traditional geophysical techniques. Here we report on short-term

Effects of extreme rainfall on phreatic eruptions: A case study of Mt. Ontake in Japan
AIMS GeosciencesSometimes, natural disasters caused by volcanic eruptions have tragic consequences. Phreatic eruptions are large explosions of steam rocks and hot water caused by the sudden evaporation of water to steam. The September 2014 eruption of Mt.

Earth, Planets and Space, 2018 On Ioto Island (Iwo-jima), 44 phreatic eruptions have been recorded since 1889, when people began to settle there. Four of these eruptions, after the beginning of continuous observation by seismometers in 1976, were accompanied by intense seismic ...

Phreatic and Hydrothermal Eruptions: From Overlooked to Looking Over
Bulletin of Volcanology, 2022 Over the last decade, field investigations, laboratory experiments, geophysical exploration and petrological, geochemical and numerical modelling have provided insight into the mechanisms of phreatic and hydrothermal eruptions. These eruptions are driven

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

Geological study of phreatic eruptions
The Journal of the Geological Society of Japan, 2018 Phreatic (non-juvenile) eruptions are the most common type of magmatic activity on Earth. Here we review the characteristics of phreatic eruptions, which occur when overheated water is rapidly vaporized.

Kusatsu-Shirane volcano as a site of phreatic eruptions
The Journal of the Geological Society of Japan, 2018 This paper reviews the hydrothermal systems of Kusatsu-Shirane volcano, Japan, which are associated with phreatic eruptions. The existence of hydrothermal systems at this volcano is easily explained: hot springs are derived from unique thermal water that

Earth, Planets and SpaceThe 2014 phreatic eruption of Mt. Ontake was preceded by increased volcano-tectonic (VT) seismicity, but all other types of precursors were obscure. A subsurface process leading to eruption with few precursors has yet to be identified.
