Chronology of the 2015 eruption of Hakone volcano, Japan: geological background, mechanism of volcanic unrest and disaster mitigation measures during the crisis

Earth, Planets and Space, 2018
The 2015 eruption of Hakone volcano was a very small phreatic eruption, with total erupted ash estimated to be in the order of only 102 m3 and ballistic blocks reaching less than 30 m from the vent.

Soil CO2 Degassing and Temperature at Poás Volcano: Evidence From the 2025 Eruptive Phase

Geofluids, Volume 2026, Issue 1, 2026.
Soil carbon dioxide (CO2) degassing provides valuable insights into volcano–hydrothermal systems, especially during their active phases. Soil CO2 flux and temperature surveys are particularly useful where direct access to vents is limited, providing information on subsurface magmatic dynamics.

Overview of the eruption of Soufriere Hills Volcano, Montserrat, 18 July 1995 to December 1997

, 1998
The onset of phreatic volcanic activity at the Soufriere Hills volcano, Montserrat on 18 July 1995 followed a three-year period of heightened volcano-sesimic activity beneath the island.

InSAR analysis for detecting the route of hydrothermal fluid to the surface during the 2015 phreatic eruption of Hakone Volcano, Japan

Earth, Planets and Space, 2018
Although the 2015 Hakone Volcano eruption was a small-scale phreatic eruption with a discharged mass of only about 100 tons, interferometric synthetic aperture radar successfully detected surface deformations related to the eruption.

Interactive 3D simulation of Taal Volcano eruption plumes

Applied Computing and Geosciences
The Taal Volcano in the Philippines is one of the most active volcanoes due to its recurrent, sometimes highly destructive eruptions, especially the 12 January 2020 phreatomagmatic eruption classified as VEI=4.

Experimental constraints on phreatic eruption processes at Whakaari (White Island volcano)

Journal of Volcanology and Geothermal Research, 2015
AbstractVigorous hydrothermal activity interspersed by sequences of phreatic and phreatomagmatic eruptions occur at Whakaari (White Island volcano), New Zealand. Here, we investigate the influence of sample type (hydrothermally altered cemented ash tuffs and unconsolidated ash/lapilli) and fragmentation mechanism (steam flashing versus gas expansion ...

The chronology of the Aegean late bronze age with special reference to the "Minoan” eruption of Thera [PDF]

, 2002
The chronology of the Aegean Late Bronze Age is a vigorously contested area of archaeological study, with "high" and "low" schemes emerging over the last three decades.

Phreatic eruptions and deformation of Ioto Island (Iwo-jima), Japan, triggered by deep magma injection

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 ...

Detecting dynamical regimes by Self-Organizing Map (SOM) analysis: An example from the March 2006 phreatic eruption at Raoul Island, New Zealand Kermadec Arc

, 2013
We propose a technique to improve the analysis of volcanic seismic data and highlight possible dynamical or precursory regimes, by using an efficient class of artificial neural network, the Self-Organizing Maps (SOMs).

Reconstruction of a phreatic eruption on 27 September 2014 at Ontake volcano, central Japan, based on proximal pyroclastic density current and fallout deposits [PDF]

, 2016
The phreatic eruption at Ontake volcano on 27 September 2014, which caused the worst volcanic disaster in the past half-century in Japan, was reconstructed based on observations of the proximal pyroclastic density current (PDC) and fallout deposits ...
