Three-dimensional, multiphase flow numerical models of phreatic volcanic eruptions.
Explosive volcanic eruptions are characterized by the ejection in the atmosphere of volcanic gases and fragments of magma and/or lithics at high temperature, pressure and velocity. They encompass a broad range of magnitudes, with volumes of ejecta spanning from less than 106 m3, to 109-1011 m3 of Plinian eruptions, up to the largest known volcanic ...Tomaso Esposti Ongaro +1 more

Phreatic eruptions and the influence of hydrothermal alteration on their processes
2016Phreatic eruptions are possibly the most drastic surface expressions of hydrothermal activity within active epithermal systems (geothermal fields), and they are still poorly understood. Various phenomena, such as fumaroles, hot springs, mud pools, and soil encrustations represent further obvious features of the interaction between outgassing ...

Probable dynamic triggering of phreatic eruption in the Tatun volcano group of Taiwan
Journal of Asian Earth Sciences, 2017Abstract On 16 March 2014 (UTC), a small phreatic eruption occurred in the Tatun volcano group (TVG) of Taiwan, although it was not reported until analysis of both seismic and acoustic data revealed that the source was in the vicinity of the Hsiaoyukeng fumarole.
