A numerical model for precursory time sequences of the phreatic eruptions of Mt. Ontake, central Japan

open access: yesEarth, Planets and Space
The 2014 phreatic eruption of Mt. Ontake was preceded by increased volcano-tectonic (VT) seismicity, but all other types of precursors were obscure. A subsurface process leading to eruption with few precursors has yet to be identified.

Time Varying Crustal Anisotropy at Whakaari/White Island Volcano

open access: yesGeophysical 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.

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

open access: yes, 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.

Magma feeding system of the 1893 CE Meiji eruption of Azumayama Volcano, NE Japan

open access: yesEarth, Planets and Space
Azumayama Volcano is one of the most active stratovolcanoes in northeastern Japan, with a ca. 1.2 million-year eruption history. Its hazard status was raised to volcanic alert level 2 (restricted access to the crater) in 2018 and 2019 due to an increase ...

MAARS OF SOUTH-CENTRAL OREGON By [PDF]

open access: yes
If we could go back in time some 5 to 10 million years to the Pliocene Epoch and recreate the landscape of south-central Oregon, here are some of the things we would probably see: From a plain originally of slight relief, faulting has already ...
