Expanding OCO‐2's Volcanic Observation Record to the Low‐Intensity 2021 Fagradalsfjall and the Ninth Sundhnúkur Crater Row Eruptions

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Since 2021, Iceland experienced 12 volcanic eruptions, all located on the Reykjanes peninsula. From these events, the 2021 Fagradalsfjall and the ninth Sundhnúkur crater row (16 July–5 August 2025) eruptions were detected by the Orbiting Carbon Observatory‐2 (OCO‐2).

Properties of the Magma and Modified Magma Equations

Journal of the Physical Society of Japan, 1990
Solutions of the “magma equation”, f t =[ f n {( f - m f t ) x -1}] x , are investigated for compact support initial conditions. It is shown analytically that traveling wave solutions with compact support do not exist for this equation. Numerical integration demonstrates that although initial conditions with compact support produce solitary waves ...

Silicic Magmas (Magma Formation in the Crust)

1971
In deeply eroded ancient fold regions, levels are exposed at which silicic magma was once generated. From the field of abyssal geology proper, we now move over to conditions of investigation more customary to us, and it may be comparatively easy to draw some conclusions.

Magma supply, magma ascent and the style of volcanic eruptions

Earth and Planetary Science Letters, 2007
Abstract We propose a new way of looking at the sequence of events leading to different styles of silicic, volcanic eruptions. Small-to-medium sized eruptions, either explosive or effusive, are explained by the ascent of isolated magma batches from mid-crustal magma chambers.

Magma Redox Geochemistry

2021
The redox state is one of the master variables behind the Earth's forming processes, which at depth concern magma as the major transport agent. Understanding redox exchanges in magmas is pivotal for reconstructing the history and compositional make-up of our planet, for exploring its mineral resources, and for monitoring and forecasting volcanic ...
