Fagradalsfjall mountain is a tuya that erupted during the last glaciation under the ice shield. The broader Fagradalsfjall volcanic system comprises an area of eruptive fissures (fissure swarm), cones and lava fields in the southern part of the Reykjanes peninsula.
A strong seismic crisis began in the area near Fagradalsfjall since late Feb 2021, interpreted as intrusion of magma at shallow depth. This led to the first historic eruption of the volcano on 19 March 2021, followed by a similar, but smaller eruption in August 2022.

Sfondo

According to Catalogue of Icelandic Volcanoes used by the Global Volcanism Project's database, the Fagradalsfjall fissure swarm is considered the southwestern branch or a secondary part of the larger Krýsuvík–Trölladyngja volcanic system. However, we follow different publications that regard Fagradalsfjall as own volcanic system (or volcano in a wider sense).
Fadradalsfjall mountain is a Pleistocene table mountain in the Reykjanes Peninsula NE of Grindavik, and the remnant of a subglacial eruption during the latest glaciation.
