Abstract

Geoscience The last volcanic supereruption—defined as having an eruption volume of more than 1000 cubic kilometers—occurred about 27,000 years ago. In a Perspective, Papale and Marzocchi argue that if such an event were to occur today, it could pose an existential risk to humanity. Indeed, even a smaller eruption like that of Mount Tambora in the Lesser Sunda Islands, Indonesia, in 1815 has the potential to disrupt global economic activity. Although it is not possible to predict the eruption volume of individual volcanoes, statistical considerations suggest that the probability of a Mount Tambora–scale or larger eruption is sufficiently high to warrant the development of resilience plans for such an event.
