Non-explosive eruptions of lava and less-violent explosive eruptions have occurred in and near the Yellowstone Caldera since the last super eruption. The most recent lava flow occurred about 70,000 years ago, while the largest violent eruption excavated the West Thumb of Lake Yellowstone around 150,000 years ago. Smaller steam explosions occur ...
This eruption of 2,450 km 3 (590 cu mi) of material is thought to be one of the largest known eruptions in the Yellowstone hotspot's history. This eruption, 2.1 million years ago, is the third most recent large caldera-forming eruption from the Yellowstone hotspot. It was followed by the Mesa Falls Tuff and the Lava Creek Tuff eruptions.

Known large eruptions after the Paleogene period (from 66 Mya to 23 Mya) are listed, especially those relating to the Yellowstone hotspot, Santorini caldera, and the Taupō Volcanic Zone. 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.
This list summarizes the major expeditions to the Yellowstone region that led to the creation of the park and contributed to the protection of the park and its resources between 1869 and 1890. 1871 Hayden Survey at Mirror Lake en route to East Fork of the Yellowstone River, August 24, 1871-William H.

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]
