This short documentary follows a team of volcanologists from the University of Geneva (UNIGE) as they head to the 2021 Cumbre Vieja Eruption on the Island of La Palma, Spain. Working alongside the local INVOLCAN observatory, who was monitoring the evolution of eruption, the UNIGE volcanologists focused more on sampling and analysing the ash and lava flows which can then be compared against historical eruptions. The scientists explain how investigating the mineral and glass content of the fossil and current lava will offer better insight into how eruptions of this type evolve.
