Increased rates of deformation and seismicity are well-established precursors to volcanic
eruptions, and their interpretation forms the basis for eruption warnings worldwide. Rates of …

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 …

The two volcanic eruptions of 2021 and 2022 at Fagradalsfjall in SW Iceland occurred within
the Reykjanes Peninsula Oblique Rift, a segment of the complex boundary in Iceland …

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 …

Cyclic behaviour is observed in volcanic phenomena ranging from caldera collapses to
explosions, spattering or lava fountaining. The repeating processes can define irregular …

Abstract The Geldingadalir and Meradalir eruptions at Mt. Fagradalsfjall in the Reykjanes
Peninsula on 19 March 2021 and 3 August 2022, respectively, were preceded by intense …

The deep roots of volcanic systems play a key role in the priming, initiation, and duration of
eruptions. Causative links between initial magmatic unrest at depth and eruption triggering …

The Fagradalsfjall eruption commenced on 19 March 2021 on a~ 180-m-long eruptive
fissure, following a 23-day dike intrusion. New eruptive fissures opened northeast of the …

Following two periods of dike intrusion in 2021 at Fagradalsfjall, Iceland, one of which led to
an eruption, a third dike intrusion commenced on 30 July 2022. A sudden increase in …

We use a dense seismic network on the Reykjanes Peninsula, Iceland, to image a group of
earthquakes at 10–12 km depth, 2 km north-east of 2021 Fagradalsfjall eruption site. These …
