Yellowstone's Not Overdue for an Eruption

Surprise Explosion at Yellowstone

At around 1000 AM MST on July 23, 2024, a small hydrothermal explosion occurred in Yellowstone National Park in the Biscuit Basin thermal area. The explosion shot steam, water, and dark rock fragments into the air, and was felt by visitors in the area. No injuries were reported.

Yellowstone's Eruption History

Yellowstone's supervolcano last erupted 700,000 years ago. While the volcano is not overdue for an eruption, it is still active and eruptions can occur at any time. The park is monitored closely by scientists who are looking for signs of an impending eruption.

Hydrothermal Explosions

Hydrothermal explosions are caused by the sudden release of steam and water from heated groundwater. These explosions can be powerful and can cause damage to the surrounding area. However, they are not as powerful as volcanic eruptions and do not pose a threat to the public.
