Infrasonic gliding reflects a rising magma column at Mount Etna (Italy)
Infrasound is increasing applied as a tool to investigate magma dynamics at active volcanoes, especially at open-vent volcanoes, such as Mt. Etna (Italy), which are prodigious sources of infrasound. Harmonic infrasound signals have been used to constrain

A Data-Based Minimal Model of Episodic Inflation Events at Volcanoes
Space geodetic time series, be they ground-based or space-based, have increased in length and accuracy. These series can now be mined for information on the qualitative dynamics of volcanic systems directly from surface deformation data.

Insight into subvolcanic magma plumbing systems [PDF]
The Island of Hawaii, which is among the best-studied volcanic islands on Earth, provides lush ground for debates in volcanology that focus on how magmatic systems evolve in space and time. Hawaiian volcanoes evolve through four eruptive stages that are characterized by distinct composition ...

Effusive eruptions dominate the eruptive record of many arc volcanoes and may hold crucial information about their plumbing systems, yet they are underrepresented in geochemical and petrological studies.

Deep Magma Transport Control on the Size and Evolution of Explosive Volcanic Eruptions
Explosive eruptions are the surface manifestation of dynamics that involve transfer of magma from the underground regions of magma accumulation. Evidence of the involvement of compositionally different magmas from different reservoirs is continuously ...

Ankaramite from Tenerife: a novel geothermobarometric approach to gain insights into the depth of a magma plumbing system [PDF]
This study investigates the magma plumbing system of the Miocene volcano shield stage of Tenerife (Canary Islands) through a geothermobarometric analysis of clinopyroxenes in ankaramite dykes and lavas from the Teno and Roque del Conde massifs ...

Modeling the Intermittent Lava Lake Drops Occurring Between 2015 and 2021 at Nyiragongo Volcano
Between 2015 and 2021, Nyiragongo's lava lake level experienced a linear increase punctuated by fast intermittent drops. These drops occurred synchronously to seismic swarm at approximately 15 km below the surface and extending laterally NE from the ...

Understanding Fast and Slow Unrest at Volcanoes and Implications for Eruption Forecasting
This paper examines the behavior of volcanoes that erupt quickly with paroxysmal explosive eruptions, and other volcanoes that erupt over extended periods without such paroxysmal activity.

The Interconnected Magmatic Plumbing System of the Natron Rift
Understanding the magmatic plumbing system of rift volcanoes is essential when examining the interplay between magmatic and tectonic forces. Recent seismicity, volcanic activity, magma emplacement, and volatile release make the Natron basin the ideal ...

Constraining the pre-eruptive processes that modulate the chemical evolution of erupted magmas is a challenge. An opportunity to investigate this issue is offered by the interrogation of the crystals carried in lavas.
