Understanding and forecasting phreatic eruptions driven by magmatic degassing [PDF]

open access: yesEarth, Planets and Space, 2018
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 Rica (Turrialba and Poás) which are currently highly active and hazardous ...

Phreatic eruptions at Whakaari Volcano driven by hydrothermal mineralisation and magmatic gas input [PDF]

open access: yesCommunications Earth & Environment
Phreatic eruptions are a potentially lethal type of volcanic activity that is notoriously difficult to forecast. Understanding the complex processes that make eruptions more likely is a key step towards detecting precursory signals.

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

open access: yesNature Communications, 2022
Volcanic eruptions that occur without warning can be deadly in touristic and populated areas. Using a machine learning approach, the authors here discover distinctive patterns hidden in the seismic signals of a number of New Zealand and Alaskan volcanoes,

Sensitivity to lunar cycles prior to the 2007 eruption of Ruapehu volcano [PDF]

open access: yesScientific Reports, 2018
A long-standing question in Earth Science is the extent to which seismic and volcanic activity can be regulated by tidal stresses, a repeatable and predictable external excitation induced by the Moon-Sun gravitational force.

Groundwater Interacting at Depth With Hot Plastic Magma Triggers Phreatic Eruptions at Yugama Crater Lake of Kusatsu-Shirane Volcano (Japan)

open access: yesFrontiers in Earth Science, 2021
Interpreting the triggering mechanisms for phreatic eruptions is a key to improving the hazard assessment of crater lakes. Yugama Crater Lake at Kusatsu-Shirane volcano, Japan, is the site of frequent phreatic eruptions with the recent eruptions in 1982 ...

Hidden pressurized fluids prior to the 2014 phreatic eruption at Mt Ontake [PDF]

open access: yesNature Communications, 2022
Phreatic volcanic eruptions can be unexpected and devastating. Here the authors, using seismic-based methodologies, find that pressurized fluids accumulated 5 months before the deadly phreatic eruption at Mt Ontake; a period previously considered as ...

The 2019–2020 volcanic eruption of Late’iki (Metis Shoal), Tonga [PDF]

open access: yesScientific Reports, 2022
Late’iki (previously known as Metis Shoal) is a highly active volcano in the Tofua arc with at least four temporary island-building eruptions and one submarine eruption in the last 55 years.

Insights Into the Mechanisms of Phreatic Eruptions From Continuous High Frequency Volcanic Gas Monitoring: Rincón de la Vieja Volcano, Costa Rica

open access: yesFrontiers in Earth Science, 2019
Understanding the trigger mechanisms of phreatic eruptions is key to mitigating the effects of these hazardous but poorly forecastable volcanic events.

Anatomy of phreatic eruptions

open access: yesEarth, Planets and Space, 2018
This study investigates phreatic eruptions at two similar volcanoes, Kawah Ijen (Indonesia) and White Island (New Zealand). By carefully processing broadband seismic signals, we reveal seismic signatures and characteristics of these eruptions.
