Kusatsu-Shirane volcano eruption on January 23, 2018, observed using JMA operational weather radars

Earth, Planets and Space, 2021
A phreatic eruption suddenly occurred at Motoshirane (Kusatsu-Shirane volcano, Japan) at 10:02 JST on January 23, 2018. A member of the Japan Self-Defense Force was killed by volcanic blocks during training in Motoshirane, and 11 people were injured by ...

Fluid circulation pattern inside La Soufrière volcano (Guadeloupe) inferred from combined electrical resistivity tomography, self-potential, soil temperature and diffuse degassing measurements [PDF]

, 2014
International audienceAfter a drastic decline in 1983, hydrothermal activity at La Soufrière lava dome (Guadeloupe, Lesser Antilles) has been progressively increasing in the summit area since 1992, raising the threat of a renewed eruptive activity.

Magmatic priming of a phreatic eruption sequence: The 2012 Te Maari eruptions at Mt Tongariro (New Zealand) imaged by Magnetotellurics and Seismicity

Geophysical Journal International
Magnetotelluric data from Mount Tongariro has been analysed using an unstructured tetrahedral finite-element inversion code that incorporates topography, which was not included in previous analysis of these data.

Evidence for a new shallow magma intrusion at La Soufrière of Guadeloupe (Lesser Antilles). Insights from long-term geochemical monitoring of halogen- rich hydrothermal fluids [PDF]

, 2014
International audienceMore than three decades of geochemical monitoring of hot springs and fumaroles of La Soufrière of Guadeloupe allows the construction of a working model of the shallow hydrothermal system.

Vulnerability of Aso Volcano’s Disaster Mitigation System, as Revealed by the Phreatic Eruption of October 20, 2021

Journal of Disaster Research
At Aso volcano, phreatic and phreatomagmatic eruptions have repeatedly caused volcanic disasters with fatalities near the crater. While it is important to conduct research on eruption forecasting for reducing the risk to tourists and climbers of this ...

Accurate hindcasting of explosive eruptions at Whakaari, New Zealand

Volcanica
Phreatic eruptions are small, sudden events, commonly with few precursory signals. They are driven by interactions between magmatic and hydrothermal processes at shallow levels beneath the surface.

Landslide Character and Hydrological Thresholds for Slope Failure Initiation on Volcanic Scoria Slopes: Case Study From Mt Hobson/Ōhinerau, Auckland, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Rainfall‐induced landslides involving on Auckland Volcanic Field scoria cones are highly unusual, compared with widespread landsliding in the surrounding Auckland clay‐rich residual soils. Indeed, while Auckland can suffer from thousands of rainfall‐induced shallow landslides from severe storms at subdecadal timescales, these are usually limited to ...
