The most recent one—Taupo, in New Zealand—occurred 26,500 years ago. One from 74,000 years ago—Toba, in Indonesia—left behind a caldera, or giant crater, about the size of Rhode Island. The biggest one yet identified—La Garita, in Colorado—coughed out 1,200 cubic miles of volcanic materials. On this map, sample a selection of the aptly named though thankfully extremely rare natural cataclysms known as "supereruptions."
