Magnetotelluric Imaging of a Magma Plumbing System From the Asthenosphere to Crust Beneath the Newer Volcanic Province, Australia

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract The Newer Volcanic Province (NVP) in southeastern Australia is a classic example of continental intraplate volcanism located far from a plate boundary, yet the configuration of its magma plumbing system remains unclear. Using three‐dimensional (3D) magnetotelluric (MT) inversion, we imaged a vertically continuous, trans‐lithospheric conductive

The Buoyancy of Cratonic Lithospheric Mantle

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Cratons are generally thought to be characterized by stable, long‐lived mantle roots. However, recent studies have suggested that the lithospheric mantle may be prone to removal, implying that it may be denser than the asthenosphere. To address these suggestions, we use a global data set of mantle xenoliths to estimate the density structure of

Fine Tuning Eruption Source Parameters to Improve Ash Dispersion Simulations: An Example From Eyjafjallajökull 2010

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.
Abstract Volcanic ash dispersion simulations and remote sensing of ash clouds are conducted by volcano observatories and Volcanic Ash Advisory Centres to monitor and forecast the evolution of volcanic ash clouds in space and time in order to mitigate the risk posed by these events on civil aviation.

Statistical Models for Infrasonic Propagation: Application to the Detection Capability of the Global IMS Network

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.
Abstract The detection capability of the global infrasound International Monitoring System (IMS) deployed to monitor compliance with the Comprehensive Nuclear‐Test‐Ban Treaty is highly variable in space and time. Previous studies estimated the source energy of near‐surface explosions from remote observations using empirical yield‐scaling relations ...
