Seismic Velocity Monitoring Reveals Complex Magma Transport Dynamics at Kīlauea Volcano Prior to the 2018 Eruption

open access: yesAGU Advances
Magma and pressure transport between Kīlauea's summit reservoirs and along its East Rift Zone (ERZ) are dynamic even in the absence of surface eruptions.

Seismic anisotropy reveals stress rotation caused by magmatic-tectonic interactions in the Natron rift

open access: yesFrontiers in Earth Science
Oldoinyo Lengai volcano is located within the Natron Rift, a young magmatic segment of the East African Rift System, where tectonic extension and magmatic processes are tightly coupled.

Three-dimensional Ocean Dynamics and Detectability of Tidally Locked Lava Worlds

open access: yesThe Astrophysical Journal
Tidally locked lava planets are hot, rocky worlds on close-in orbits with a permanent molten dayside. With JWST, their surfaces and atmospheres are beginning to be revealed.

Scaling of Gas–Melt Decoupling in Silicic Eruptions: Magma Ascent, Connected Permeability, and Atmospheric Confinement

open access: yesApplied Sciences
Gas escape relative to magma ascent is a primary control on degassing, yet its governing parameters are difficult to compare across eruptions and planetary environments. This study develops a reduced-order dimensionless framework for diagnosing local gas–

A model of volcanic magma transport by fracturing stress mechanisms

open access: yesGeophysical Research Letters, 2008
Understanding the mechanisms of magma ascent preceding eruptions, and in particular the subvolcanic system that stores and transports magma to the surface, is of crucial relevance for hazard and risk assessment. We propose here a statistical model describing the rise of magma from the reservoir through the transport region via stress induced fracturing

Space-Based Imaging Radar Studies of U.S. Volcanoes

open access: yesFrontiers in Earth Science, 2019
The arrival of space-based imaging radar as a revolutionary land-surface mapping and monitoring tool little more than a quarter century ago enabled a spate of innovative volcano research worldwide.

Buoyancy-driven crack propagation from an over-pressured source [PDF]

open access: yes, 2005
The propagation of a liquid-filled crack from an over-pressured source into a semi-infinite uniform elastic solid is studied. The fluid is lighter than the solid and propagates due to its buoyancy and to the source over-pressure.

Petrogenesis of Erg Chech 002 Achondrite and Implications for an Altered Magma Ocean

open access: yesThe Astrophysical Journal
This study conducts mineralogical and chemical investigations on the oldest achondrite, Erg Chech 002 (∼4565 million yr old). This meteorite exhibits a disequilibrium igneous texture characterized by high-Mg-number (atomic Mg/(Mg + Fe ^2 ...
