Mud Creek landslide shoreface erosion

A series of images shows the height of a landslide and how it erodes over time.

Detailed Description

In 2017, the massive Mud Creek landslide buried a quarter-mile of the famous coastal route, California’s Highway 1, with rocks and dirt more than 65 feet deep. USGS monitors erosion along the landslide-prone cliffs of Big Sur, collecting aerial photos frequently throughout the year. By analyzing overlapping photos, they made precise maps of the slopes and calculated volumes of material lost or gained over time. The last slide in this animation shows the differences between the May 27, June 13, and June 26 photos, calculating the volume of land lost or gained.
