Landslides — This photo shows one of the houses damaged by the 2005 Laguna Beach Landslide. The house experienced an undermining of the landslide but remained intact. The October 2, 1978 Bluebird Canyon landslide in Orange County California cost, $52.7 million, 60 houses destroyed or damaged. Unusually heavy rains in March of 1978 may have contributed to initiation of the landslide. Although the 1978 slide area was approximately 3.5 acres, it is suspected to be a portion of a larger, ancient landslide. A large, translational landslide, called the Laguna Beach, CA landslide occurred in June, 2005. This landslide severely damaged or destroyed 19 homes, and resulted in the evacuation of 345 homes. There were no serious injuries or loss of life. The 2005 landslide is located about 200 feet east of the 1978 Bluebird Canyon landslide. Photo credit: Pam Irvine, California Geological Survey (CGS).
