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]
