This month, #Yellowstone Volcano Observatory Scientist-in-Charge Mike Poland reports from the site of a 3000-year-old hydrothermal explosion crater on the north side of Yellowstone Lake. He describes this underappreciated volcanic hazard before reviewing seismicity and deformation that occurred in the Yellowstone region during the month of August. Geyser activity is also featured, with a short video (recorded by Yellowstone National Park scientist Stan Mordensky) showing the eruption of Gantess

Mike Poland, scientist-in-charge of the Yellowstone Volcano Observatory, describes activity at Yellowstone in this monthly update for August 1, 2022. The August 1 update comes to you from beautiful Mammoth Hot Springs in Yellowstone National Park. Tens of millions of years ago, this area was a shallow inland sea. The bedrock geology includes sandstones and slates, and even limestones composed of the shells of small marine organisms that accumulated over time. This area is also a zone of persiste
