Gases Dictate Etna's Explosive Tempo | Science News
Mount Etna’s eruptions reveal a hidden drama beneath the surface—some unfold over weeks with magma cooling slowly, others erupt in hours from 30km deep. Scientists at Cornell have cracked the code: it’s all about volcanic gases like carbon dioxide and water vapor. High CO2 triggers explosive, deep blasts; more water leads to slower, shallower events. Think of it like shaking a soda bottle—gas pressure builds until it explodes. This breakthrough lets researchers map magma pathways globally, improving eruption predictions and understanding the invisible forces shaping our planet’s most…
