Fieldworks

Cumbre Vieja vulcano, La Palma, Spain

Taking samples from lava that is just a couple of days old to study recording properties of basalt. With access to the exclusion zone, we were able to sample the rims of the active flow in three different locations. The images and footage we made inside the exlcusion zone got widespread attention on Dutch national tv and in a leading newspaper. Field work together with Romy Meyer (PhD candidate), October 2021.
