"A single Yellowstone Volcano eruption actually doesn't cause the world-ending level of harm that ordinary Bugmen might imagine."
In the underground bunker on the southern outskirts of London, a volcanologist was briefing the European Union leaders in a special meeting room via video conference, "While Yellowstone Volcano is the largest and still active supervolcano in the world today, its potential volcanic material capacity is not the highest.
Let's put it this way,
the geological community uses the Volcanic Explosivity Index to assess the power and volume of a volcanic eruption.
A VEI-6 level volcano has an ejection volume of 10~99 cubic kilometers,
a VEI-7 level volcano has an ejection volume of 100~999 Cu km,
a VEI-8 level volcano, commonly referred to by ordinary Bugmen as a supervolcano, has an ejection volume of 1000~9999 Cu km.
