New Study Reveals Magma Pooling Triggered 2021 Icelandic Eruption

Geochemical analysis shows crustal contamination in early lava flows, challenging previous theories

Researchers discovered that magma pooled beneath the Earth's crust before the Fagradalsfjall eruption.
Early lava samples showed significant crustal contamination, unlike later samples from the same eruption.
The study suggests that crustal magma storage may be a common precursor to large basaltic eruptions.
Findings could improve volcanic hazard forecasting by identifying potential eruption triggers.
The study also draws parallels with the 2021 Tajogaite volcano eruption in the Canary Islands.
