Earth, Planets and Space, 2016 The sudden eruption of Mount Ontake on September 27, 2014, led to a tragedy that caused more than 60 fatalities including missing persons. In order to mitigate the potential risks posed by similar volcano-related disasters, it is vital to have a clear understanding of the activity status and progression of eruptions.

Seismic Tremor as a Precursor to Hydrothermal Explosions Near Mutnovsky Volcano (Kamchatka)
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Mutnovsky Volcano, ∼70 km SW of Petropavlovsk‐Kamchatsky, exhibits persistent degassing, hosts active hydrothermal springs and the Mutnovsky Geothermal Power Plant (MGPP) on its slopes. Using the network covariance matrix approach, we analyzed seismic data recorded in 2023–2024 by 15 seismic stations operating around Mutnovsky Volcano.

Depositional record of historic lahars in the Whangaehu Gorge, Mt. Ruapehu [PDF]
, 2008 Mt. Ruapehu is one of the most lahar prone volcanoes in the world, having both a crater lake and six small glaciers upon its 2797 m summit. The major outlet for the crater lake, the Whangaehu Gorge, has hosted over 46 historic lahars.

The sequence of the 2017–2018 eruptions and seismo-acoustic activity at Kirishima volcano group
Earth, Planets and Space, 2023 Kirishima volcano consists of more than 20 eruptive centers. Among them, Shinmoe-dake had magmatic eruptions in October 2017 and March 2018. Subsequently, another active cone, Iwo-yama, had phreatic eruptions in April 2018.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract Titanomagnetite in alkaline maar deposits exhibits variable syn‐ and post‐crystallization alteration linked to wet emplacement and groundwater fluctuations, which remain poorly documented. Magnetic and mineralogical analyses of lapilli, scoria, and basalt from ICDP Eger drill cores S4 and S4b (Bažina maar, western Eger Graben, Czechia) reveal ...

Hydrothermal alteration and sealing at Turrialba as a mechanism for phreatic eruption triggering
, 2021 <p>Turrialba is a basaltic to andesitic Holocene stratovolcano that after decades of quiescence re-activated in 1996 and has been highly active ever since. Turrialba is characterized by a highly active magmatic-hydrothermal system, and we propose that hydrothermal sealing and volatile accumulation are the mechanisms responsible for the ...

Phreatic eruption at 864 AD of Fuji volcano caused by entry of Aokigahara lava flows into the old lake "Se-no-umi" [PDF]
, 2011 We studied the mechanism of probable phreatic eruptions caused by the entry of lava flow into old Lake "Seno-umi" at Lake Shouji district during the 864 Fuji eruption.

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract Long‐term SO2 emission rate time series are critical for deciphering the subsurface processes regulating open‐vent volcanoes, yet extracting cyclical drivers from continuous degassing records remains challenging. We analyze a 14‐year (2006–2020) SO2 emission rate data set from Whakaari/White Island, New Zealand, identifying five chronological ...
