The caldera is the enormous volcanic crater left from the last time Yellowstone experienced a giant eruption, 640,000 years ago. It covers an area about 30 by 45 miles .
The Yellowstone Caldera formed over 600,000 years ago from the Lava Creek Tuff eruption, which was measured on the Volcanic Explosivity Index as an 8, according to the U.S. Geological Survey ...
Active volcanoes such as Stromboli, Mount Etna and Kīlauea do not appear on this list, but some back-arc basin volcanoes that generated calderas do appear. Some dangerous volcanoes in "populated areas" appear many times: Santorini six times, and Yellowstone hotspot 21 times.

[4] [5] It is a popular site for tourists. [6] Map of Yellowstone Volcano ash beds
The duration of an eruption affects the interval that will elapse before the next eruption, so that if the duration of an eruption is recorded, the time of the following eruption can be predicted to a precision of about two hours. around 1-2 hours the geyser overflows and drains until it gets so strong it reaches 1 meter and this is the start ...
