USGS Imagery assessment of landslide extent and severity (as of 07/01/26, 4:30 PM MDT). Verification remains ongoing. Color is based on USGS’s remote assessment. Landslide impact is classified as “Unknown” (yellow), “Minor or none” (green), “Localized” (orange), or “Major or Widespread” (purple).

Recent landslide on the east face of Mt. King George (3741 m) with clouds of dust from ongoing rockfall. Debris descended over 1500 m to the glacier below. Photo courtesy of Yukon Geological Survey. 

Large landslide on the southwest side of Mt. King George. The main debris lobe is 1800 m wide, and material would have travelled approximately 6 km from the source area (triangular scar) in the background. Photo courtesy of Yukon Geological Survey.

Landslides on the northeast side of Mt. King George with clouds of rock dust in the air caused by ongoing activity. Elevation difference between the peak and the glacier is at least 1700 m. Also note the numerous collapsed snow bridges on the glacier. Photo courtesy of Yukon Geological Survey.

Landsat 9 true color, pan-sharpened satellite image collected on December 10, 2025, showing landslides triggered by the M7.0 Hubbard Glacier Earthquake on the slopes of Mount King George. Landslide points were mapped from SAR change detection.

Overview maps at the same scale showing the epicenter of the M7.0 Hubbard Glacier Earthquake and modeled peak ground acceleration contours. A) shows the probability of landslides triggered by the earthquake and mapped faults, and B) shows the locations of landslides mapped using synthetic aperture radar (SAR) change detection.

Animation of Sentinel-1 radar backscatter satellite imagery from November 28^th and December 9^th, 2025, showing the changes in surface roughness after the M7.0 Hubbard Glacier Earthquake. The lighter regions have rougher surface areas. The colored points correspond to preliminary mapping of potential mass movements.

Postfire runoff in the 2024 Elk Fire buran area near Dayton, Wyoming. Near the outlet of a burned watershed, postfire runoff deposited small boulders and mud, flattening the vegetation in this low-relief area.
