What can corals tell us about volcanic eruptions? Is it possible corals, in the span of their lives, have recorded valuable data on volcanic eruptions they have witnessed? Today we find it out together with Prof. Tom Sheldrake, who takes us on a journey through coral reefs and volcanic eruptions, giving voice to what corals want to tell us about volcanic activity! Introducing Professor Tom Sheldra ...[Read More]

Machine Learning and Volcanic Crystals: a journey with Corin Jorgenson into Random Forest Thermobarometry
Thermobarometry: a bit of background Being able to understand the eruptive style of a volcano, how the eruptive behavior can evolve over time and managing to better interpret the signals that a volcanic system gives us before an eruption are of fundamental importance for mitigating the risk associated with eruptive activities. In this context, it is extremely important to understand trans-crustal ...[Read More]
