Towards Viscosity Monitoring

Abstract: Viscosity exerts a first order control on volcanic eruption dynamics. Throughout effusive eruptions, lava viscosity evolves continuously. In order to accurately describe and interpret eruptive behavior, many viscosity measurements must thus be acquired. Recent technical advances in the field finally enable quick experimental turnaround, making viscosity tracking throughout an eruption possible. Results show that viscosity monitoring invaluably complements other eruption monitoring techniques: monitoring viscosity changes can help anticipate eruptive style variations, as well as reveal subsurface magmatic processes. Preliminary data also indicate that viscosity trends can shed light on the progression of an eruption, including offering cues on eruption cessation timing.
