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

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

Phreatic eruptions at Whakaari Volcano driven by hydrothermal mineralisation and magmatic gas input [PDF]
Communications Earth & EnvironmentPhreatic 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.

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

Fluid flow of CO2-driven geyser activity as inferred from tilt and self-potential observations of the Kibedani Geyser Japan [PDF]
Scientific ReportsWe conducted multi-parameter, multi-site observations at the Kibedani Geyser, Japan, where cold spring-water eruptions (20 °C) are driven by underground CO2 pressure.

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

Upper holocene tephro-chronostratigraphy of Irazú Volcano, Costa Rica [PDF]
Scientific ReportsIrazú is one of the largest and most active volcanoes in Costa Rica. We present the tephro-chronostratigraphy of the last 2.6 ka of the Irazú volcano based on detailed field work and C14 radiometric dating, as well as a revision of the geological and ...
