Time series of vertical displacements during April–October 2017 at four GPS stations (LAK1, LAK2, LKWY, and SEDG) on the north side of Yellowstone Lake. Downward trends indicate subsidence and upward trends show uplift. Uplift “spikes” in late September are related to inclement weather and do not show true deformation. Error bars are one standard deviation.

Changes in snow conditions at a gravity station in Yellowstone National Park in 2017. Each photo is taken from about the same location in May, July, August, and October of that year. The red circle in the May photograph shows the location of the gravity station in this area, which is near Craig Pass, a few miles southeast of Old Faithful.

Map of gravity stations measured in 2017 in Yellowstone National Park. Yellow lines are roads, dashed line marks the caldera boundary, black line outlines Yellowstone National Park, green circles note resurgent domes, and red dots are gravity stations.

Equipment for measuring carbon dioxide and methane emissions used to monitor changes at Steamboat Geyser in 2019. The white cylinder is the chamber, which is lowered to the ground. Gases emitted from the ground surface accumulate in the chamber. An instrument in the cart continuously measures gas concentrations and carbon isotope compositions.
