Seismic Precursors to the Whakaari 2019 Phreatic Eruption detected in Five Other Volcanoes [PDF]
Abstract 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 because their precursors are hard to recognize and can vary between volcanoes. Here, we describe a general seismic precursor signal for gas-driven eruptions,

Abstract Seismicity during non‐eruptive periods is useful for observing stress changes related to magmatic transport and volatile exsolution within active volcanoes. Mount St. Helens in Washington, USA, is the most active volcano in the continental United States and has been in quiescence since 2008. To explore the processes driving seismicity at Mount

We investigate a volcanic hydrothermal system using numerical simulations, focusing on change in crater temperature. Both increases and decreases in crater temperature have been observed before phreatic eruptions.

MOESM1 of Anatomy of phreatic eruptions
Additional file 1. Spectrograms of harmonic tremor at White Island. Harmonic tremor recorded at White Island after a seismic quiescence of 20 min, and lasting for 8 h. a station WIZ b stations WSRZ. We used a window of 20 s without any overlap to create the spectrograms.

Satellite Geodesy Reveals Shallow, Transient Magma Intrusions at Sotará Volcano, Colombia
Abstract Sotará is a little‐known andesitic‐dacitic stratovolcano in southwestern Colombia. Although there are no recorded historical eruptions, the volcano shows clear evidence of geothermal activity, deformation, and volcano‐tectonic seismicity. Its remote location and rugged terrain pose challenges for access and routine monitoring.

ABSTRACT The sudden removal of large portions of a volcanic edifice through collapse can cause depressurisation in the subvolcanic magmatic system, influencing the nature of subsequent eruptions. At Mt. Taranaki, edifice failure has occurred frequently and at different timescales throughout the volcanic history, forming a broad pattern of cyclic ...

Identification of unambiguous signals of volcanic unrest is crucial in hazard assessment. Processes leading to phreatic and phreatomagmatic eruptions remain poorly understood, inhibiting effective eruption forecasting.

Aeromagnetic survey in Kusatsu-Shirane volcano, central Japan, by using an unmanned helicopter
Kusatsu-Shirane volcano is one of the active volcanoes in Japan. Phreatic explosions occurred in Mt. Shirane in 1983 and most recently, in 2018, in Mt. Motoshirane.
