2025 Hubbard Earthquake Landslide Hazards Field Photos

By Landslide Hazards Program December 19, 2025

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.

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.

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.

Large landslides on the southwest side of Mt. King George. The main debris lobe on the right is approximately 1000 m wide. The elevation difference between the peak and the glacier is approximately 1900 m.

Landslides on the west side of Mt. King George. The central debris lobe is 500 m wide.

Landslides and avalanches on the east side of McArthur Peak. The left-hand debris lobe is 1100 m wide, and the right-hand debris lobe is 1500 m wide. The elevation difference between the peak and the glacier is approximately 1500 m.

Snow avalanche on the north side of Mt. King George. The debris lobe is 1800 m long and runs up onto the hillside across the valley.

Snow avalanches in the valley on the east side of McArthur Peak.

Large snow avalanche in valley east of McArthur Peak. Debris lobe is 1500 m wide.

Collapsed snow bridges on crevasse field on the Hubbard Glacier between McArthur Peak and Mt. King George.

Landslides on the arete between Mt. Vancouver and Mt. Logan. Elevation difference between the central peak and the glacier is 500 m.

Seracs in an icefall on the east side of Mt. Vancouver (4812 m), toppled by shaking. Field of view is approximately 3.5 km wide.

2025 M7.0 Hubbard Glacier Earthquake-Triggered Landslides and Snow Avalanches

A M7.0 oblique-slip earthquake initiated about 10 km below the Hubbard Glacier in the St. Elias Mountains about 88 km north of Yakutat, Alaska, at approximately 11:40am AKST (1:40pm YST) on December 6, 2025. The U.S. Geological Survey (USGS) Ground Failure product estimated that landslides triggered by this earthquake would likely be significant in number and/or spatial extent. This was confirmed...
