A graph showing the relationship between eruption volume and time between eruptions, using the models presented in Carrichi and others (2014). Notice how for buoyancy-driven eruptions (in blue), the time between eruptions doesn’t vary much across a wide range of volumes. Image: Figure 3 from Caricchi and others (2014), Nature Geoscience.
The study’s upshot is that Yellowstone Caldera (and the other 20+ supervolcano sites) are more likely than previously thought to explode without the aid of an earthquake. A big one could drastically lower global...
