supervolcano
Catastrophic magma reservoir
A supervolcano is a volcano capable of eruptions thousands of times more powerful than ordinary volcanic events, ejecting enough material to affect global climate.
The term typically applies to volcanoes that have produced eruptions of magnitude 8 on the Volcanic Explosivity Index.
Yellowstone sits atop one: Scientists monitor the Yellowstone supervolcano for signs of activity.
