Crystal Clusters Contain Clues to Magma’s Past and Future Eruptions
It’s now become easier to forecast the next eruption of Alaska’s Bogoslof volcano. New research led by Pavel Izbekov, a volcanologist at the Alaska Volcano Observatory, is applying the foundations of diffusion chronometry—the study of chemical change in crystals over time—to a new eruption forecasting approach. Izbekov’s team used crystal clusters and their collective records […]
