A supervolcano is an unusually large volcano with the potential to produce an eruption with major effects on the global climate system.
Recommendations
In The Precipice: Existential Risk and the Future of Humanity, Toby Ord offers several policy and research recommendations for handling risks from supervolcanic eruptions:[1]
Find all the places where supervolcanic eruptions have occurred in the past.
Improve the very rough estimates on how frequent these eruptions are, especially for the largest eruptions.
Improve our modeling of volcanic winter scenarios to see what sizes of eruption could pose a plausible threat to humanity.
Liaise with leading figures in the asteroid community to learn lessons from them in their modeling and management.
