What kind of volcano is Fagradalsfjall?

Fagradalsfjall is classified as a Fissure vent in Iceland. Its tectonic setting is Rift zone / Oceanic crust (< 15 km).

How is seismicity near Fagradalsfjall monitored here?

Earthquakes within 50 km of the crater are aggregated from 18 seismic networks and checked against a swarm rule that compares the current rate with this volcano's own 30-day background. Ash advisories come from the VAAC centres that are connected.

Dormant for some 6,000 years until 2021, when the Reykjanes peninsula reawakened. Each eruption has been announced weeks in advance by dense swarms of small earthquakes as magma forced its way through the crust — the textbook case this site's swarm detector is built around.
