Near-surface magma flow instability drives cyclic lava fountaining at Fagradalsfjall, Iceland
Lava fountains are a common manifestation of basaltic volcanism. While magma degassing
plays a clear key role in their generation, the controls on their duration and intermittency are …

Magma plumbing architectures and timescales of magmatic processes during historical magmatism on the Reykjanes Peninsula, Iceland
In the past 4000 years, three rifting episodes have occurred on the Reykjanes Peninsula
(RP, SW Iceland) at time intervals of about 800-1000 years, with the activation of four of the …

[HTML][HTML] Satellite derived SO2 emissions from the relatively low-intensity, effusive 2021 eruption of Fagradalsfjall, Iceland
In March 2021 an effusive eruption began at the Fagradalsfjall volcanic system in Iceland,
ending nearly 800 years of dormancy on the Reykjanes peninsula. The eruption produced …

Recent advances in characterizing the crustal stress field and future applications of stress data: Perspectives from North America
JE Lundstern - Geological Society, London, Special Publications, 2024 - lyellcollection.org
The stress field controls patterns of crustal deformation, including which faults are likeliest to
cause earthquakes or transmit fluids. Since the 1950s, maps of maximum horizontal stress …

Simultaneous rift-scale inflation of a deep crustal sill network in Afar, East Africa
Decades of studies at divergent plate margins have revealed networks of magmatic sills at
the crust-mantle boundary. However, a lack of direct observations of deep magma motion …

Tremor clustering reveals pre-eruptive signals and evolution of the 2021 Geldingadalir eruption of the Fagradalsfjall Fires, Iceland
Analyzing seismic data in a timely manner is essential for potential eruption forecasting and
early warning in volcanology. Here, we demonstrate that unsupervised machine learning …

Repeated seismic swarms near Paricutin volcano: precursors to the birth of a new monogenetic volcano in the Michoacán-Guanajuato volcanic field, México?
The birth of a new monogenetic volcano is difficult to forecast with precision, both in space
and time. Nevertheless, seismic activity can alert of the imminence of such an eruption …

Fracturing and tectonic stress drive ultrarapid magma flow into dikes
Many examples of exposed giant dike swarms can be found where lateral magma flow has
exceeded hundreds of kilometers. We show that massive magma flow into dikes can be …
