Seismo‐Acoustic Evidence for Meteoric Water Modulation of Hydrothermal Fluid Discharge

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Deciphering the signal of external processes on active hydrothermal dynamics represents a critical challenge in understanding volcanic unrest. At the Pisciarelli hydrothermal site, located within the densely populated Campi Flegrei caldera (Italy), we investigate the role of meteoric water influx in modulating shallow hydrothermal fluid ...

Fault Roughness Controls Seismicity Front Migration During Fluid Injection

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The increasing occurrence of injection‐induced earthquakes has raised public concern and highlighted the importance of understanding subsurface processes and mechanisms to assess induced seismic hazards and risks. We develop a simple physics‐based model to investigate how fault roughness controls the migration of seismicity during fluid ...

Modeling the Impact of Initiation Parameters on the Dynamics of the 2012 Te Maari Laterally Confined Debris Avalanche

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Volcanic debris avalanches can transform into highly mobile debris flows, reaching long runout distances and posing significant hazards to downstream populations. This high mobility arises from complex, evolving rheological behavior driven by dynamic changes in pore pressure, internal resistance, and material properties during the flow.

Variational and Monte Carlo Methods for Bayesian Inversion of Dynamic Subsurface Flow Simulations Using Seismic and Fluid Pressure Data

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract In order to predict future performance of subsurface fluid reservoirs under possible operating scenarios, a dynamic, porous‐medium flow simulation model must be tuned to include representative properties of the reservoir. Estimating subsurface reservoir properties given remotely sensed or borehole‐based observations typically involves finding ...

Pockmarks, Mud Volcanoes and Hydrocarbon Seeps in the Northern Gulf of Mexico: Trends and Controls on Widespread Fluid and Gas Venting

Basin Research, Volume 38, Issue 2, March/April 2026.
Basin‐scale dataset reveals widespread hydrocarbon venting at the seafloor in the northern Gulf of Mexico. Hydrocarbon release at the seafloor is related to the occurrence of the underlying Louann salt and the gas hydrate stability zone. ABSTRACT The release of hydrocarbons, pore water and fluidized sediments impacts seafloor morphology, marine ...

Marine Mammals in the Anthropocene: Developing a Systematic Evidence Base of Threats to Nineteen Species

Mammal Review, Volume 56, Issue 1, March 2026.
Marine mammals are vulnerable to a variety of anthropogenic threats, yet a global systematic map of the literature for 19 species found both spatial and temporal disparity in research effort between threats and between species. There are knowledge gaps for species and threats, with effort unequal across many species' ranges.

Radiosonde‐to‐Space (R2S) Atmospheric Specifications: Bridging Observations and Models for Infrasound Propagation

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Infrasound propagation is inherently asymmetric and time‐dependent, making accurate atmospheric specifications essential for predicting when and where signals arrive. The Naval Research Laboratory's Ground‐to‐Space (G2S) model is widely used for this purpose, yet discrepancies between G2S predictions and observations highlight the need for ...

Why Firn Quakes

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Snow dampens sounds, but anecdotal reports concisely describe audible propagating collapse events—firnquakes—in Antarctic and Arctic snowfields. We propose combining granular and continuum mechanics to form a testable theory for conditioning, triggering, and propagation of firnquakes consistent with scarce data.
