Mountain Degradation Mechanisms on Io Based on Geologic Mapping of the Cocytus Montes Region From JunoCam Imagery

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Periodic high‐resolution imagery of Io is essential for understanding its surface evolution, from volcanic eruptions to tectonic deformation to large‐scale mass wasting. Juno flybys in 2023 and 2024 obtained imagery of the surface with the JunoCam imager at 1.8 km/pixel spatial resolution, comparable to global observations from the Galileo ...

Upper Cretaceous Seismic Stratigraphy and Magma‐Enhanced Petroleum System of the Offshore Indus Basin

Basin Research, Volume 38, Issue 1, January–February 2026.
Seismic data reveals Cretaceous stratigraphy and hydrocarbon potential beneath volcanic rocks in Offshore Indus Basin, where magmatic intrusions enhanced source rock maturation and hydrocarbon generation by 8%–18% during favourable timing coinciding with Deccan volcanism.

Using Himawari-8, estimation of SO2 cloud altitude at Aso volcano eruption, on October 8, 2016

Earth, Planets and Space, 2018
It is vital to detect volcanic plumes as soon as possible for volcanic hazard mitigation such as aviation safety and the life of residents. Himawari-8, the Japan Meteorological Agency’s (JMA’s) geostationary meteorological satellite, has high spatial ...

Phreatomagmatic eruption during the buildup of a Triassic carbonate platform (Oman Exotics): eruptive style, associated deformations, and implications on CO2 release by volcanism [PDF]

, 2006
Oman exotics represent remnants of a Triassic carbonate platform (Misfah Formation). Within these carbonates, and coeval with the sedimentation, several basaltic magmatic events occurred mainly as intrusions, also as lava flows and projections.

Facies Characterization and Volcanic Source Assignment of Marine Tephra Deposits Around São Miguel Island, Azores Archipelago

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Long‐term tephrostratigraphies of volcanic islands such as the Azores are often limited to young and incomplete subaerial records. Here, we present a Pleistocene‐Holocene marine tephra archive around the eastern islands of the Azores based on 22 marine gravity cores.

Magma Ascent and Accumulation Drives Surface Deformation and Ring Fault Seismicity Preceding the 2024 Eruption of Fernandina Volcano, Galápagos Islands

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract At caldera volcanoes, ring faults can play a key role in controlling the dynamics of unrest and patterns of associated surface deformation and seismicity. Here we show that the March 2024 eruption of Fernandina volcano was preceded by a 2.5‐year episode of magma accumulation, driving surface uplift and asymmetric seismicity on a ring fault ...

Major‐Minor‐Trace Element Analyses and Oceanographic Modeling Confirms Circumpolar Transport of the 1962 Protector Shoal Pumice Raft

Journal of Geophysical Research: Oceans, Volume 130, Issue 12, December 2025.
Abstract Pumice rafts derived from submarine eruptions can remain afloat for months or even years, traveling thousands of kilometers on ocean currents. These natural phenomena disperse marine organisms and provide important evidence for submarine volcanism yet are not fully understood.

HUNGA-TONGA-HUNGA-HA’PAI VOLCANIC ERUPTION/EXPLOSION AND TSUNAMIS OF 14-15 JANUARY 2022 – Overview and Analysis [PDF]

Science of Tsunami Hazards, 2022
The explosive eruption/collapse of the submarine portion of the volcano Hunga-Tonga- Hunga-Ha'apai (HT-HH) on the Tonga Kermadec volcanic arc in the southwest Pacific on 15 January 2022 occurred at the end of many weeks of activity. It was a truly global

Rainfall‐triggered landslides from the January 2023 1‐in‐200 year storm at Maungakiekie/One Tree Hill, Auckland, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 5, Page 1049-1063, December 2025.
ABSTRACT We describe engineering geological characteristics and failure mechanisms of shallow soil landslides activated on Maungakiekie/One Tree Hill in central Auckland, New Zealand on 27 January 2023. The hill is a scoria cone in the young Auckland Volcanic Field (AVF), and formed ∼60 ka BP.
