Connection to the deep crust

The 2021 Fagradalsfjall volcanic eruption was the first one in the area after approximately 800 years. The photo captures the fire-fountaining phase of this eruption, during which geochemistry and petrology studies show that magma was flushed out from the base of the crust to the surface, thanks to a direct connection with the deep reservoir. During this phase, the volcano emitted high funtains of lava and tephra material, showering the vicinity of the crater.
