The United States Geological Survey (USGS) confirmed that a small hydrothermal explosion took place in the Biscuit Basin area of Yellowstone National Park on Tuesday morning.
This incident happened around 10 a.m. on July 23, 2024, and was reported to occur about 2.1 miles northwest of the famous Old Faithful geyser. According to the USGS, the explosion seemed to have started near the Black Diamond Pool.
Visitors in the park were able to capture several videos of the explosion, showing people near the area just before it erupted. Thankfully, while there was damage reported to the boardwalk, no injuries have been reported so far.
For safety reasons, Yellowstone National Park officials have temporarily closed the Biscuit Basin area, including the parking lot and boardwalks, until they can assess the damage. Currently, the extent of the damage is still being evaluated. However, the Grand Loop road remains open for visitors.
The USGS noted that hydrothermal explosions happen when water underground quickly turns to steam, and these occurrences are relatively common in Yellowstone. For instance, Porkchop Geyser in Norris Geyser Basin had a similar event back in 1989, and another small explosion was recorded this past April.
More details about hydrothermal explosions are available through the USGS, which emphasizes that these events do not indicate activity within the volcanic system, which is operating at normal levels right now.
This recent explosion is not a sign of any impending volcanic eruptions nor is it caused by magma moving toward the surface. The national park and the USGS are closely monitoring conditions and will reopen the area once it is deemed safe.
