Review of explosive hydrovolcanism

K Németh, S Kósik - Geosciences, 2020‏ - mdpi.com
Hydrovolcanism is a type of volcanism where magma and water interact either explosively or
non-explosively. The less frequently used term, hydromagmatism, includes all the processes …

Monogenetic volcanism: personal views and discussion

K Németh, G Kereszturi - International Journal of Earth Sciences, 2015‏ - Springer
Monogenetic volcanism produces small-volume volcanoes with a wide range of eruptive

Understanding and forecasting phreatic eruptions driven by magmatic degassing

J Stix, JM de Moor - Earth, Planets and Space, 2018‏ - Springer
This paper examines phreatic eruptions which are driven by inputs of magma and magmatic
gas. We synthesize data from several significant phreatic systems, including two in Costa …

Synthesis of hydrothermal alteration, rock mechanics and geophysical map** to constrain failure and debris avalanche hazards at Mt. Ruapehu (New Zealand)

G Kereszturi, L Schaefer, S Mead, C Miller… - New Zealand Journal …, 2021‏ - Taylor & Francis
Composite volcanoes can progressively weaken through hydrothermal alteration, which
may lead to volcano collapse, forming far-reaching debris avalanches. This work reviews …

Seismic precursors to the Whakaari 2019 phreatic eruption are transferable to other eruptions and volcanoes

A Ardid, D Dempsey, C Caudron, S Cronin - Nature communications, 2022‏ - nature.com
Volcanic eruptions that occur without warning can be deadly in touristic and populated
areas. Even with real-time geophysical monitoring, forecasting sudden eruptions is difficult …
