A graben is an elongate depressed crustal unit or block that is bounded by faults on its long sides. It is a structural form which may or may not be geomorphologically expressed as a rift valley.

Active Faults; Buildings; Damage; Deformation; Earthquakes; Faults; Geologic Hazards; Grabens; Land Subsidence; Plate Tectonics; SeismologyView of Fourth Avenue buildings in downtown Anchorage showing the damage from a landslide in this area. Before the 1964 earthquake (9.2 magnitude), the sidewalk on the left was level with the streen on the right. The graben subsided about 11 feet in response to 14 feet of horizontal movement on the slide block during the quake. Lateral spreading produced a fan-shaped slide that covered 36 acres and moved a maximum of 17 feet.

View to southeast. Jurassic sediments; note that the younger Morrison formation in the graben is at the same level as the older Entrada sandstone at the left. Solution of evaporites in the underlying Pennsylvanian Paradox formation caused the graben to form. Image taken April 13, 1966.
