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 ...

Time Variation in the Chemical and Isotopic Composition of Fumarolic Gasses at Kusatsu-Shirane Volcano, Japan

Frontiers in Earth Science, 2019
Minor seismicity may occur at volcanoes with hydrothermal system before a steam eruption. To forecast any steam eruption, it is indispensable to detect and understand the nature of this shallow seismicity. As the fumarolic gas resides in the hydrothermal

Geothermal and Mineralogic Analysis of Hot Springs in the Puracé‐La Mina Sector in Cauca, Colombia

Geofluids, Volume 2019, Issue 1, 2019., 2019
Thermal waters are natural resources of great value to geothermal sciences, the tourism industry, and health. In this work, geochemical classification of physicochemical results of 17 sources at the Puracé‐La Mina (Cauca, Colombia) sector was implemented in order to strengthen and determine their potential applications and enhance the continental ...

Seismological analysis of conduit dynamics in fragmentation experiments

Journal of Geophysical Research: Solid Earth, Volume 119, Issue 3, Page 2215-2229, March 2014., 2014
AbstractWe simulate gas‐burst and volcanic explosions under controlled laboratory conditions inducing fragmentation of volcanic rocks by rapid depressurization. A series of experiments were performed in a shock‐tube apparatus at room temperature and a pressure range of 4 to 20 MPa using Argon (Ar) gas and, particles or pumice samples of different ...

Long period seismic source characterization at Popocatépetl volcano, Mexico

Geophysical Research Letters, Volume 39, Issue 20, 28 October 2012., 2012
The seismicity of Popocatépetl is dominated by long‐period and very‐long period signals associated with hydrothermal processes and magmatic degassing. We model the source mechanism of repetitive long‐period signals in the 0.4–2 s band from a 15‐station broadband network by stacking long‐period events with similar waveforms to improve the signal‐to ...

Arc Heat Flow and Magmatic Heat Budgets

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

Critical Factors That Control Hydrothermal Circulation Within Active Volcanoes: Constraints From Numerical Simulation Based on a Resistivity Structure Model

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 2, February 2025.
Abstract Numerical modeling is a valuable approach for quantitative elucidation of the highly complex hydrothermal processes within active volcanoes. Various schemes have been developed for the numerical simulation of volcanic hydrothermal systems, generally employed in combination with other geophysical and geochemical monitoring techniques.
