Analysing volcanoes to predict their awakening

A team of geologists reviewed the literature on volcanic eruptions, determining that most magma rising from depth doesn't cause an eruption. Older volcanoes produce less frequent but larger eruptions. The analysis helps refine models to reduce the impact of volcanic eruptions on nearby populations.
