Detailed Description
A close-up of one of the scarps bounding the graben of the "L" Street landslide, showing a house which was undercut by subsidence of the graben. A subsidence trough (or graben) formed at the head of the "L" Street land slide in Anchorage during the 1964 earthquake. The slide block, which is the virtually unbroken ground moved to the left. The subsidence trough sank 7 to 10 feet in response to 11 feet of horizontal movement of the slide block.
