Disaster risk analysis of Mount Bromo eruption after the 2015 eruption in Sukapura District

MATEC Web of Conferences, 2018
Mount Bromo is one of the most active volcanoes in East Java with a 4-5 year interval of the eruption. Its last eruption was in 2015 and is expected to erupt in 2020.

Magmatic Volatile Flux Drives Non‐Eruptive Volcano‐Tectonic Seismicity at Mount St. Helens, USA From 2008–2024

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
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

Anatomy of active volcanic edifice at the Kusatsu–Shirane volcano, Japan, by magnetotellurics: hydrothermal implications for volcanic unrests

Earth, Planets and Space, 2020
We aimed to perform three-dimensional imaging of the underlying geothermal system to a depth of 2 km using magnetotellurics (MT) at around the Yugama crater, the Kusatsu–Shirane Volcano, Japan, which is known to have frequent phreatic eruptions.

Satellite Geodesy Reveals Shallow, Transient Magma Intrusions at Sotará Volcano, Colombia

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
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.

Changes in seismic anisotropy at Ontake volcano: a tale of two eruptions

Seismica
The interaction of faults, fractures, and hydromagmatic systems of volcanoes can lead to complicated stress patterns that vary over short spatial and temporal scales.

Chronology of the 2015 eruption of Hakone volcano, Japan: geological background, mechanism of volcanic unrest and disaster mitigation measures during the crisis

Earth, Planets and Space, 2018
The 2015 eruption of Hakone volcano was a very small phreatic eruption, with total erupted ash estimated to be in the order of only 102 m3 and ballistic blocks reaching less than 30 m from the vent.

Stratigraphy and lithosedimentological properties of subplinian eruptions from Mt. Taranaki, New Zealand, encompassed by the Ngaere and Pungarehu edifice collapses

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 722-746, December 2025.
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 ...

InSAR analysis for detecting the route of hydrothermal fluid to the surface during the 2015 phreatic eruption of Hakone Volcano, Japan

Earth, Planets and Space, 2018
Although the 2015 Hakone Volcano eruption was a small-scale phreatic eruption with a discharged mass of only about 100 tons, interferometric synthetic aperture radar successfully detected surface deformations related to the eruption.
