Every year since 2017, the Yellowstone Volcano Observatory has summarized yearly geological activity—earthquakes, ground deformation, geyser eruptions, and so forth—and research efforts and findings in a series of annual reports. In these products you can find information about the numbers of seismic swarms in a given year, or the progress made on geologic mapping and dating of Yellowstone deposits, and even the thermal emissions from Yellowstone National Park as detected by satellites.
