SALT LAKE CITY — A hydrothermal explosion at Yellowstone National Park’s Biscuit Basin, captured on camera early Tuesday, is under investigation as experts aim to better predict these potentially dangerous events, which occur up to twice annually in the park, according to a seismologist at the University of Utah.
Jamie Farrell, a research associate professor at the University of Utah Seismograph Stations and the chief seismologist at the Yellowstone Volanoc Observatory, explained that hydrothermal explosions can cause significant damage, though they usually take place in less frequented areas of the park. “They can get really big and very destructive,” he acknowledged, noting his relief that Tuesday’s explosion did not result in any injuries.
The explosion prompted officials to temporarily close the affected area after it caused considerable damage, highlighting the sometimes volatile nature of the park’s geothermal features. “What happened shouldn’t alarm anyone about any larger potential volcanic activity at the park,” Farrell reassured.
Known for its picturesque landscapes interspersed with geothermal activity, Yellowstone sits atop a volcanic hotspot, presenting unique hazards. Farrell referred to hydrothermal explosions as “an underappreciated hazard,” triggered when underground pressures cause water to suddenly turn into steam, creating an explosive effect.
Farrell disclosed that he had observed a smaller explosion in the same area 15 years prior, underscoring the recurrent nature of these incidents. He also revealed that new equipment had already been placed in another area of the park to monitor these phenomena, with plans to extend this setup to include Biscull Basin following the recent incident.
In the aftermath of the explosion, Farrell plans to visit Yellowstone to evaluate the site and the new equipment installed, which could provide valuable data to predict future events, thereby enhancing safety measures for park visitors. “Through the equipment installed, we hope to learn more about how the explosions work and if there are signals that can predict them so people can be warned ahead of time,” Farrell commented.
He emphasized the importance of such studies, highlighting the unpredictable nature of geological activities. “We get reminders every once in a while that there are things we have no control over,” he stated.
As scientists continue working to understand and mitigate the risks associated with Yellowstone’s hydrothermal activity, such events serve as stark reminders of the dynamic and sometimes dangerous environment of one of America’s most beloved national parks. With ongoing research and monitoring, experts like Farrell are crucial in efforts to safeguard the millions of visitors drawn to Yellowstone each year.
