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 ...

Journal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.Abstract Nakhlites, clinopyroxene‐rich rocks, are the largest single‐origin suite of samples from Mars. Despite extensive study to discern their petrogenetic histories, nakhlite emplacement mechanisms and environments are not well‐constrained, and it is unknown whether they represent intrusive or extrusive igneous rocks, or a combination.

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.

The communication of volcano information in New Zealand – a narrative review
New Zealand Journal of Geology and Geophysics, Volume 68, Issue 4, Page 591-608, December 2025.ABSTRACT Communication of volcano information is critical for effective volcanic risk management. A variety of information is communicated to inform decisions and guide actions for planning, preparedness, and response. Such information needs to be reliable, and fit‐for‐purpose across different stages of volcanic activity (quiescence, unrest, short or ...

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 ...

Beyond Cumulative Sum Charting in Non-Stationarity Detection and Estimation
IEEE Access, 2019 In computer science, stochastic processes, and industrial engineering, stationarity is often taken to imply a stable, predictable flow of events and non-stationarity, consequently, a departure from such a flow. Efficient detection and accurate estimation

Sheet flow caves of Kilauea Caldera, Hawaii County, Hawaii [PDF]
International Journal of Speleology, 1998 Terminal lobes of sheet flows of pahoehoe lava sometimes form three-dimensional nests, initially separated by partitions consisting of accreted ‘skins” of each lobe. Melting breaks down these partitions, forming a uniform flow unit. In Kilauea Caldera we

Hollow volcanic tumulus caves of Kilauea Caldera, Hawaii County, Hawaii [PDF]
International Journal of Speleology, 1998 In addition to lava tube caves with commonly noted features, sizable subcrustal spaces of several types exist on the floor of Kilauea Caldera. Most of these are formed by drainage of partially stabilized volcanic structures enlarged or formed by ...
