USGS Imagery assessment of landslide extent and severity (as of 07/16/26). 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).

Electrical resistivity at lower-crustal depths (35 km) beneath the contiguous U.S. The architecture of the nation is revealed at this depth with warm colors marking active extension beneath the western U.S.

A well-traveled data logger used over the course of the USMTArray. Custom MT instruments purchased at the start of the USMTArray supported the 18 year effort.

The starting view is from January, 1970, a field photo of Punta Ventana (“Window Point”) at Guayanilla, Puerto Rico (Monroe, 1980). The image fades to the March 5, 2020 color photo of the same location (ten Brink, 2020). The natural arch had collapsed from earthquake shaking on January 6, 2020 during the 2020 Southwest Puerto Rico Earthquake Sequence.

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. 

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.

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.

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. Photo courtesy of Yukon Geological Survey.

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. Photo courtesy of Yukon Geological Survey.

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.  Photo courtesy of Yukon Geological Survey.

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.
