On July 23, 2024, Yellowstone National Park experienced yet another hydrothermal explosion. This time, the event occurred in Biscuit Basin around 10 a.m., sending people running for safety and damaging a boardwalk.
The eruption originated near Black Diamond Pool and was relatively small compared to previous incidents, according to reports from the U.S. Geological Survey (USGS) and the National Park Service.
Despite no injuries being reported, Biscuit Basin was temporarily closed for investigation. Visitors were advised to stay clear of the area while geologists assessed the damage and determined its cause.
Hydrothermal explosions are a common occurrence in Yellowstone National Park. They happen when superheated water rapidly flashes to steam underground, creating an explosion that can send debris flying and destroy nearby structures.
Similar events have occurred in Biscuit Basin before, including one in 2009 that expelled foot-sized ejecta and caused a sensation of heat. Another hydrothermal explosion took place at Norris Geyser Basin on April 15, 2024.
Despite the frequent occurrence of these explosions, they are not connected to volcanic activity in the park. Instead, they are a result of geothermal systems that experience changes underground and release built-up pressure.
Visitors to Yellowstone National Park should remain vigilant and stay on designated trails and boardwalks when visiting thermal areas. These areas can be dangerous due to their fragile nature and the potential for sudden eruptions.
The USGS continues to monitor Yellowstone National Park for any signs of volcanic activity or hydrothermal explosions. They encourage visitors to check their website for updates on park conditions and closures.
