6/6 After the 2021 eruption, magma accumulated and fractionated at near-Moho depths. In 2022–2023, a looser mush network enabled faster magma assembly. Diffusion modelling, barometry, and geophysical data show dikes started propagating ~1 month before eruption, then breached the upper crust in days.

5/6 Plg timescales in 2022–23 record mush erosion over months to years, progressively shortening with time, suggesting a loosened mush and faster response to deep melt input. Ol timescales (days-weeks) reflect timing and duration of dike ascent from near-Moho depths, correlating with pre-seismicity

4/6 The 2021–2023 Fagradalsfjall eruptions were sourced from a persistent near-Moho magma domain. However, cpx–melt barometry suggests that in 2022–2023, magmas stalled at mid-crustal levels or ascended more slowly, unlike in the 2021 eruption.

3/6 Unlike 2021, the 2022–2023 Fagradalsfjall lavas show limited geochemical variability, likely sourced from a single, well-mixed reservoir. Trace element ratios and isotopes lie along 2021 mixing trends, suggesting little changes in melt compositions over three years.

2/6 In 2022–2023, olivine (ol) and clinopyroxene (cpx) are phenocrysts, while plagioclase (plg) crystals are antecrysts eroded from crystal mushes. This contrasts with 2021, when all crystals had antecrystic origins, suggesting two distinct crystal populations in the 2022-2023 eruptions.

1/6 We investigate the 2022–2023 Fagradalsfjall eruptions to track short-term changes in magmatic processes and timescales beneath the volcano. Our petrological and geochemical data are integrated with published data from the 2021 eruption (Halldórsson et al. 2022; Kahl 2023; Marshall 2024).

Mush disaggregation and dike propagation timescales at active volcanoes – Evidence from the 2022-2023 Fagradalsfjall eruptions
Abstract. The architectures of magma plumbing systems and timescales of magmatic processes are fundamental to understanding volcanic eruption dynamics. Thi
🚨🌋New paper on the geochemistry and petrology of the 2022–23 Fagradalsfjall eruptions on the Reykjanes Peninsula, Iceland. We study temporal variations in the magmatic plumbing system and link diffusion timescales to monitoring signals, tracing the timing of mush disaggregation and dike propagation

Medieval arch in the historical centre of Perugia
Leaving Iceland for now, along with the Reykjanes eruptions! However, I am happy to share that I have started a postdoc at the University of Perugia, working with Maurizio Petrelli and collaborators on the 2021 La Palma eruption 🌋

Aerial image showing the main lava river at the beginning of the November 2024 eruption at Sundhnúksgígar, Iceland.
This photo shows the November 2024 eruption at Sundhnúksgígar after a day of activity, when most lava flowed west. White smoke comes from the Svartsengi geothermal power plant, and black smoke from the burning Blue Lagoon parking lot. The barriers are doing a great job protecting the infrastructure

Thank you! I am actually not familiar at all. Hopefully I can edit it now
