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 ...

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 ...

Time Varying Crustal Anisotropy at Whakaari/White Island Volcano

Geophysical Research Letters
Whakaari/White Island has been the most active New Zealand volcano in the 21st century, producing small phreatic and phreatomagmatic eruptions, which are hard to predict.

Volcanic impact on stratospheric aerosol chemistry [PDF]

Samples collected by the National Center for Atmospheric Research (NCAR) using the multiple-filter sampler on the U-2 were analyzed. The sampler is capable of exposing a number of 110 mm filters in sequence to ram air flow.

Phreatomagmatic eruption during the buildup of a Triassic carbonate platform (Oman Exotics): eruptive style, associated deformations, and implications on CO2 release by volcanism [PDF]

, 2006
Oman exotics represent remnants of a Triassic carbonate platform (Misfah Formation). Within these carbonates, and coeval with the sedimentation, several basaltic magmatic events occurred mainly as intrusions, also as lava flows and projections.
