ALT OpenTopography topographic differencing with NOAA lidar shows how the Earth’s surface changed from 2010-2014. The left image shows a lidar hillshade. In the right image, the difference between the 2010 and 2014 datasets is shown. Red indicates where the land surface moved down or was eroded. Blue shows where the land surface moved up or where material was deposited. Topographic analysis of these older lidar datasets indicates that landslide activity has been persistent in this area for decades.
ALT The 2017 Mud Creek landslide occurred along the Big Sur coastline of central California, approximately 140 kilometers south of San Francisco. The red areas indicate zones of erosion or material loss, while blue areas highlight where the displaced material was deposited.
