Magma ups and downs recorded by melt embayments during the 2021 Fagradalsfjall eruption, supp. material

We analyzed volatile diffusion profiles in olivine hosted melt embayments gathered from the tephras of the 2021 eruption of the Fagradalsfjall. These embayments provides constrains over the magma decompression and ascent rates, as well as hints towards the existence of successive compression/decompression events which can be interpretated as convection cells.<br>
