USGS analysis of air photos collected June 13 shows that new land created by a May 20 landslide on California’s Big Sur coast is eroding.
USGS analysis of air photos collected June 13 shows that new land created by a May 20 landslide on California’s Big Sur coast is eroding. The large slide buried State Highway 1 beneath more than 65 feet of rock and dirt, and created about 13 acres of new land bulging into the ocean. Between May 27 and June 13, the seaward edge of the landslide retreated about 16 feet. USGS scientists collect air photos of the slide area weekly to biweekly as weather permits. They use “structure-from-motion” software to turn the photos into 3D maps from which they measure changes in ground elevation.
