Phreatomagmatic eruptions through unconsolidated coastal plain sequences, Maungataketake, Auckland Volcanic Field (New Zealand) [PDF]

Journal of Volcanology and Geothermal Research, 2014
Abstract Maungataketake is a monogenetic basaltic volcano formed at ~ 85–89 ka in the southern part of the Auckland Volcanic Field (AVF), New Zealand. It comprises a basal 1100-m diameter tuff ring, with a central scoria/spatter cone and lava flows. The tuff ring was formed under hydrogeological and geographic conditions very similar to the present ...

Seawater-magma interactions sustained the high column during the 2021 phreatomagmatic eruption of Fukutoku-Oka-no-Ba [PDF]

Communications Earth & Environment, 2022
High eruption plumes during submarine eruptions are promoted by seawater vaporisation and decoupled from erupted mass, according to combination of satellite remote sensing observations and plume modelling.

Large-magnitude (VEI ≥ 7) ‘wet’ explosive silicic eruption preserved a Lower Miocene habitat at the Ipolytarnóc Fossil Site, North Hungary [PDF]

Scientific Reports, 2022
During Earth’s history, geosphere-biosphere interactions were often determined by momentary, catastrophic changes such as large explosive volcanic eruptions.

Pyroclastic density currents associated with the 2015 phreatomagmatic eruption of the Kuchinoerabujima volcano [PDF]

Earth, Planets and Space, 2018
A pyroclastic density current (PDC) was observed with the phreatomagmatic eruption of the Kuchinoerabujima volcano, southern Japan, on May 29, 2015. The PDC flowed down in all direction from the source crater, forming three major branches.

The 1723 A.D. violent strombolian and phreatomagmatic eruption at Irazú Volcano, Costa Rica

Revista Geológica de América Central, 2013
The largest of the recorded historic eruptions at Irazú volcano began on February 16, 1723 and lasted until at least December 11. We here critically examine deposits of this eruption exposed on the summit of Irazú.
