On Tuesday’s Late City Edition, tune in for a conversation with Philipp Ruprecht, a volcanologist at Columbia University’s Lamont-Doherty Earth Observatory. Ruprecht recently co-authored a study concerning eruption forecasting with Terry Plank, a geochemist at Lamont-Doherty. The study, published in the journal Nature, is entitled “Feeding andesitic eruptions with a high-speed connection from the mantle.” Tune in for our discussion about the team's research on Costa Rica’s largest stratovolcano eruption, their insights into rising magma rates, and how their work might improve eruption forecasting.
