Effects of extreme rainfall on phreatic eruptions: A case study of Mt. Ontake in Japan

AIMS Geosciences
Sometimes, 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.

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 ...

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.

Persistent Deep Long‐Period Seismicity Near the Lassen Volcanic Center

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Deep long‐period (DLP) earthquakes have been observed at many volcanic settings around the world and linked to the magmatic processes that drive volcanic unrest. At the Lassen Volcanic Center (LVC) of the Cascade arc, limited detection of DLP activity hinders classification of anomalous seismic behavior and its relationship to the LVC magmatic

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.
