   Yellowstone installs new monitoring camera after Biscuit Basin explosion

   Yellowstone National Park installed a new camera to monitor hydrothermal activity over a wider area following a June 13, 2026, explosion at Biscuit Basin. That blast produced a new boiling pool and a 60-foot long crack filled with boiling water, which was recorded by acoustic and seismic equipment. Separately, the Giant Geyser, the park's second largest, has erupted twice in the last two months. These events highlight ongoing geothermal volatility within the park's hydrothermal systems.

   Why it matters

   Hydrothermal explosions occur when superheated water flashes to steam, often creating new geological features. Monitoring these events helps officials track subsurface pressure and heat changes. This activity is distinct from volcanic eruptions.

   What is confirmed

   • A hydrothermal explosion occurred at Biscuit Basin on June 13, 2026.
   • The June 13 event created a boiling pool and a 60-foot long crack filled with boiling water.
   • Monitoring equipment captured seismic and acoustic energy from the Biscuit Basin blast.
   • A new camera was installed to track activity over a broader area in response to the June 13 explosion.

   Still unconfirmed

   • Giant Geyser has erupted twice in two months.

   What to watch next

   • Data releases from the new wide-area monitoring camera
   • Further eruptions or explosions in the Biscuit Basin area

   Small Hydrothermal Explosion Hits Biscuit Basin

   A small hydrothermal explosion occurred early on June 13, 2026, at Biscuit Basin in Yellowstone National Park. The event created a new boiling pool and a 60-foot long crack filled with boiling water. Monitoring equipment captured seismic and acoustic energy from the blast.

   What's confirmed:

   • A small hydrothermal explosion occurred at Biscuit Basin on June 13, 2026.
   • The blast created a new boiling pool and a crack 60 feet long filled with boiling water.
   • The explosion threw rocks several tens of feet and broke open the earth.
   • Yellowstone Volcano Observatory monitoring equipment detected significant seismic and acoustic energy during the event.
   • A jet of steam emerged from new features several hundred feet north of Black Diamond Pool.
   • The June 13 event was smaller than a significant hydrothermal explosion that occurred in the same area on July 23, 2024.

   Still unconfirmed:

   • The explosion clouded the Firehole River with turbid water.
   • A new boiling pool the size of a small swimming pool appeared two days after scientists monitored the area.

   Hydrothermal Explosion at Yellowstone's Biscuit Basin

   A hydrothermal explosion at Biscuit Basin created a 20-foot crater of boiling water. The event formed a new thermal pool and vents that produced intermittent spouts 20 to 30 feet high by June 18. Some water temperatures reached 200 degrees Fahrenheit.

   What's confirmed:

   • A hydrothermal explosion occurred at Biscuit Basin in Yellowstone National Park on June 13, 2026.
   • The explosion created a 20-foot crater of boiling water.
   • The event resulted in a new thermal pool and vents.

   Still unconfirmed:

   • The explosion caused temporary closures for safety assessments.
