2022 Yellowstone Volcano Observatory Annual Report Released by USGS.
The 2022 Yellowstone Volcano Observatory annual report highlights monitoring data collected over the course of the year, including 2,429 earthquakes, subsidence of Yellowstone Caldera, and little significant deformation in the area of Norris Geyser Basin. There were no significant changes in the behavior of most geysers despite catastrophic flooding in the Yellowstone region. Research into the causes and impacts of hydrothermal explosions in Yellowstone National Park focused on the north part of Yellowstone Lake and Lower Geyser Basin. YVO scientists are also learning more about the complexity of the large volcanic explosion that formed Yellowstone Caldera 631,000 years ago.
