Geophysical Research Letters, 2022 Monitoring of active volcanic systems is a challenging task due in part to the trade‐offs between collection of high‐quality data from multiple techniques and the high costs of acquiring such data.

Eos, Transactions American Geophysical Union, 1984 Trace‐element anomalies observed in rocks located stratigraphically at the Cretaceous‐Tertiary boundary are considered significant evidence that the boundary is a record of a large meteorite impact (Science, 208, 1095–1108, 1980). In particular, trace metals, including iridium and other members of the platinum metals group, are thought to be enriched ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.Abstract Three voluminous inflated lobate lava flow complexes on the distal rifts of Axial Seamount are much larger than other known flows in the global spreading system. Each complex is 65–100 km2, is up to 130 m thick, and is ∼3.0–4.6 km3, almost 100 times the volumes of historical Axial flows.

Distribution and Transport of Thermal Energy within Magma–Hydrothermal Systems
Geosciences, 2020 Proximity to magma bodies is generally acknowledged as providing the energy source for hot hydrothermal reservoirs. Hence, it is appropriate to think of a “magma–hydrothermal system” as an entity, rather than as separate systems.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract The 2021 eruption of Cumbre Vieja on La Palma, Canary Islands, provided a unique opportunity to investigate the dynamics of magma migration and storage during a large effusive eruption. In this study, we employ repeated seismic tomography to image temporal changes in the subsurface structure beneath La Palma, using body‐wave travel times from ...

Social sensing a volcanic eruption: application to Kīlauea, 2018 [PDF]
Natural Hazards and Earth System SciencesProtecting lives and livelihoods during volcanic eruptions is the key challenge in volcanology, conducted primarily by volcano monitoring and emergency management organisations, but it is complicated by scarce knowledge of how communities respond in ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract From 2019 to 2024, gravity surveys were conducted at the Three Sisters volcanic cluster (TSVC), measuring 246 gravity sites using a spring relative gravimeter. We calculated the residual Bouguer anomaly and identified three main zones with negative anomalies, ranging from −4 to −8 mGal, located southwest and west of South Sister, within an ...

Forecasting SO2 emission of Kilauea volcano using intelligent method of data analysis
Sistemnì Doslìdženâ ta Informacìjnì Tehnologìï, 2019 Kilauea is one of the most active and well-known volcanoes in the world and most of our knowledge of volcanism originates from its research. During a long study of volcanoes, many different methods of forecasting their activity were proposed, from the ...

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract We investigated the regolith parent rock (“protolith”) properties of Mare Tranquillitatis and Marius Hills on the Moon, utilizing lunar pit craters (“lua”) to contextualize observations of rock abundance and crater degradation. We discovered a significant difference in underlying materials: the region around the Tranquillitatis lua is ...

Static stress implications for Kīlauea volcano activity after the 2018 Hawai'i earthquake
Geodesy and GeodynamicsThe MW6.9 thrust-faulting earthquake in Hawai'i on May 4, 2018, occurred near the Kīlauea shield volcano. We use 57-day-long continuous Global Positioning System (cGPS) data and 6-day-long semi-continuous GPS data to develop a detailed coseismic slip ...
