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 most recent eruption of Steamboat Geyser occurred on October 7, 2024. [10] This was the 168th eruption since it re-activated in early 2018. [11] In 2019 the 48th eruption occurred on December 26. That set a new record for the most eruptions within a calendar year. The calendar year 2020 also saw 48 eruptions, tying the record set in 2019. [12]
The Lava Creek eruption of the Yellowstone Caldera, which occurred 640,000 years ago, [100] ejected approximately 1,000 cubic kilometres (240 cu mi) of rock, dust and volcanic ash into the atmosphere. It was Yellowstone's third and most recent caldera-forming eruption.
This eruption produced more than 280 km2 of magma [7] and was nested within a portion of a larger caldera, the Huckleberry Ridge Caldera. [4] The third large eruption was about 0.6 Ma and created the Yellowstone Caldera. [4] This eruption produced 1,000 km2 of magma [7] through at least two volcanic vents. [4]

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 ...
