Geophysical examination of the 27 April 2016 Whakaari/White Island, New Zealand, eruption and its implications for vent physiognomies and eruptive dynamics

Earth, Planets and Space, 2019
At approximately 09:36 UTC on 27 April 2016, a phreatic eruption occurred on Whakaari Island (White Island) producing an eruption sequence that contained multiple eruptive pulses determined to have occurred over the first 30 min, with a continuing tremor

Analyzing the continuous volcanic tremors detected during the 2015 phreatic eruption of the Hakone volcano

Earth, Planets and Space, 2017
In the present study, we analyze the seismic signals from a continuous volcanic tremor that occurred during a small phreatic eruption of the Hakone volcano, in the Owakudani geothermal region of central Japan, on June 29, 2015.

Volcanic Radiative Power Retrieval From Moderate‐to‐Low‐Temperature Features Using a Single TIR Band: Validation Using Volcanic Crater Lakes and Hydrothermal Systems

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Assessing Radiative Power (RP) output is essential for monitoring and understanding volcanic systems. While Mid‐Infrared channels are used to assess thermal outputs at volcanoes exhibiting effusive activity, Thermal‐InfraRed (TIR) bands are better suited for measuring moderate‐to‐low‐temperature (≲600 K) features, such as those associated with

Possible application of compact electronics for multilayer muon high-speed radiography to volcanic cones [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2013
Compact data-taking electronics were developed for high-speed multilayer muon radiography in order to minimize operation failure rates. By requiring a linear trajectory within the position sensitive detectors (PSDs), the background (BG) events produced ...

The First Instrumentally Detected Hydrothermal Explosion in Yellowstone National Park

Geophysical Research Letters, Volume 52, Issue 11, 16 June 2025.
Abstract Hydrothermal explosions are one of the geological hazards most likely to impact people in Yellowstone National Park, but their frequency is poorly known. Infrasound and seismic sensors identified an explosion in Norris Geyser Basin on 15 April 2024, at 14:56 MDT (20:56 UTC)—the first instrumentally detected hydrothermal explosion in the ...

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.

Nature, origin and significance of a clayey cave deposit: Relationship between karst and Oligocene/Miocene tephra (NW Dinarides)

The Depositional Record, Volume 11, Issue 3, Page 954-974, June 2025.
A limestone cave in the NW Dinarides exhibits an anomalous presence of montmorillonite clay, not commonly found in surrounding caves, posing questions about its origin and age. Analysis reveals a composition similar to weathered tephra from the Smrekovec Volcanic Complex, suggesting transport by north‐east winds.

Chemistry, Growth, and Fate of the Unique, Short‐Lived (2019–2020) Water Lake at the Summit of Kīlauea Volcano, Hawaii

Geochemistry, Geophysics, Geosystems
Less than a year after the 2018 Kīlauea caldera collapse and eruption, water appeared in newly deepened Halemaʻumaʻu crater. The lake—unprecedented in the written record—grew to a depth of ∼50 m before lava from the December 2020 eruption boiled it away.

Characteristics of Deep Long‐Period Earthquakes at Alaska Volcanoes From 2005 to 2017

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Deep long‐period earthquakes (DLPs) are often detected near volcanoes from the crust down to the upper mantle. Exhibiting coincidence with volcanic eruptions, DLPs are recognized as potential precursors to volcanic activities yet their detection remains challenging.
