a Fagradalsfjall (blue-gray), 2022 Meradalir (orange), and 2023 Litli-Hrútur (green) eruptions with a background hillshade derived from previous work25,69,70. A total of 18 Fagradalsfjall, 3 Meradalir, 4 Litli-Hrútur sampling sites were established, though some are too closely spaced to be individually resolved on the map. Note that sampling sites 1, 2, 3, and 4 were from Fagradalsfjall, but were later resurfaced by new lava flows from Meradalir. Earlier in the eruption, day 1 sites were established near the eruptive vent but quickly covered. Additional sites were collected in 2024 to determine spatial variability, indicated by the black circles for Fagradalsfjall, pink triangles for Meradalir, and light green × for Litli-Hrútur. b Inset of area around Sites A–C. A late-stage breakout in September of 2021 covered Site A and the area of the flow is shown in transparent white.
