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.

Leachate Analyses of volcanic ashes from the 2010 Eyjafjallaj\uf6kull eruption [PDF]

, 2011
Volcanic processes which lead to eruptions can be investigated by monitoring a variety of parameters, including the composition of ash leachates. Fine-grained tephra erupted from active vents, and transported through volcanic plumes, can adsorb, and ...

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 ...

Suspended sediment transport diversity in river catchments following the 2014 phreatic eruption at Ontake Volcano, Japan

Earth, Planets and Space, 2019
The present contribution investigates the temporal changes in volcaniclastic sediment transport over the 2-year period after the 2014 eruption of Ontake Volcano in two small drainage basins where increased turbidity was observed immediately after the ...

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

Earth, Planets and Space, 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 ...

Origins and significance of alteration textures in hydrovolcanic products from active volcanoes

Earth, Planets and Space
While mineralization processes in hydrothermal systems have been studied intensively from the viewpoint of economic geology, the composition, and textures of hydrothermally altered materials in hydrovolcanic ash have not been fully analyzed in active ...
