Earthquake shaking can cause some sediment layers to liquify, which allows overlying layers to slide and spread apart in a lateral spread landslide. The Turnagain neighborhood near Anchorage, Alaska, was heavily damaged by a lateral spread slide during the 1964 Alaska earthquake. This video shows models of lateral spread landslides that develop when a layer of glass microbeads "liquifies" during shaking.
