SCP-8413 "Yellowstone"

Item #: SCP-8413
Object Class: Apollyon

Special Containment Procedures: SCP-8413 can not be contained, as it is a super-volcano. SCP-8413 is to be monitored by FEMA, local SCP units, and USGS (United States Geological Service). If containment breach/eruption, pray, as if SCP-8413 were to erupt, SCP-8413 would trigger all other volcanoes/super-volcanoes to erupt above VEI 5, causing massive earthquakes world wide. Can wipe out all life, including Humans, All animals, and All plants/trees/crops.
Description: SCP-8413 is the Yellowstone Super-volcano. Highly dangerous. Extremely powerful. One of the worst SCPs and one of those that can't be contained. Erupts every 600,000 years, but last eruption was 640,000 years ago, so SCP-8413 is 40,000 years overdue.
