Hot water, mud erupt from Yellowstone National Park pool

On May 31, a hydrothermal eruption occurred at Black Diamond Pool in Yellowstone National Park's Biscuit Basin. This event marks the first eruption at the site since a significant explosion on July 23, 2024, which sent steam and debris hundreds of feet into the air, damaging nearby infrastructure.

The recent eruption was captured by a newly installed webcam, indicating ongoing activity in the hydrothermal system. Scientists from the U.S. Geological Survey and the National Park Service have confirmed that such eruptions are not related to volcanic activity but result from the rapid transition of water to steam in the shallow hydrothermal system beneath the pool.
