InSAR Evidence of Small‐Scale Faults Activated During Rift Zone Intrusions at Piton de la Fournaise Volcano

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Volcanic edifices show complex internal structures including discontinuities at different scales. These discontinuities can act as zones of weakness and are closely linked to volcanic activity distribution and associated hazards, making their detection and monitoring essential. In this study we investigate the presence of small‐scale faults on

Advective structures of the bottom of lake Natron and its surroundings (Tanzania)

Руды и металлы, 2022
In this study we consider the features of the development of weakly lithified bottom sediments and the general structure of lake Natron against the background of its seasonal drying and watering.

Terrestrial Analogs to Titan for Geophysical Research

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

The origin of fresh glass in phreatic eruptions at Rincón de la Vieja and Turrialba volcanoes, Costa Rica

Volcanica
Despite involving no fresh magma, phreatic eruptions are increasingly found to contain juvenile material. This study seeks to determine whether the glass is the result of an input of new magma or shallow stalled magma passively entrained.

Rock characteristics of post-caldera volcanoes in Dieng volcanic complex (DVC), Central Java, Indonesia

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2022
The Dieng volcanic complex (DVC) has one of the densest post-caldera volcanisms activity presents in Indonesia, yet its population density is considerably high.

Arc Heat Flow and Magmatic Heat Budgets

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

Depressurization of a hydrothermal system following the August and November 2012 Te Maari eruptions of Tongariro, New Zealand

Geophysical Research Letters, 2016
In 2012, two phreatic eruptions occurred at New Zealand's Tongariro volcano for the first time in over a century. Interferometric Synthetic Aperture Radar data collected by the Italian Space Agency's COSMO‐SkyMed satellite constellation, indicates up to ...

Aeromagnetic survey in Kusatsu-Shirane volcano, central Japan, by using an unmanned helicopter

Earth, Planets and Space, 2021
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.

The August 2010 Phreatic Eruption of Mount Sinabung, North Sumatra

Indonesian Journal on Geoscience, 2013
DOI: 10.17014/ijog.v8i1.155Mount Sinabung, located in Karo Regency, North Sumatra Province, is a strato volcano having four active craters. Since its latest eruption about 1,200 year ago, a phreatic eruption occurred on August 27th, 2010. The eruption took place in Crater-I, which was initiated by a greyish white plume and then followed by black plumes

Temporal Change in Resistivity Structure Before and After the 2018 Small Phreatic Eruption Iwo‐Yama Volcano, Kirishima Volcanic Complex, Japan

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A small phreatic eruption occurred on April 2018 Iwo‐yama, Kirishima volcanic complex, Japan. We estimated the change in the subsurface resistivity structure before and after the phreatic eruption by repeated magnetotelluric (MT) measurements. A substantial decrease in resistivity was determined in the zone from the surface down to a depth of ...
