Spectrogram of a possible long-period (LP) earthquake in Yellowstone that occurred on August 26, 2021, near Norris Geyser Basin. The top panel shows a 30-second seismogram recorded at seismic station YHH. The bottom panel shows the spectrogram with energy concentrated in the 1–3 Hz range and lasting for ~15 seconds.

Top image is a view of the Silver Gate landslide complex, near Mammoth Hot Springs, from Bunsen Peak. Bottom shows roughly the same view using lidar data, colored to show elevation highs and lows and shaded by slope. Landslide scarps, roads, trails, and Glen Creek (lower left), all obscured by trees in the photograph, are much more visible in the lidar.

Regional map of southeastern Idaho showing the relative location of Yellowstone National Park and the Stanley earthquake aftershocks. Yellowstone National Park (outlined in yellow) is at least 275 km away from the 2020 Mw6.5 Stanley earthquake. Several active faults (in red) are located between the Stanley earthquake and Yellowstone Caldera.

Cumulative number of aftershocks greater than magnitude 2.5 following the March 30, 2020, magnitude-6.5 Stanley earthquake in central Idaho. The black line shows the observed aftershocks, the red line shows the predicted number of aftershocks. Aftershocks are a normal and expected phenomenon following strong tectonic earthquakes.
