Study identifies California cliffs at risk of collapse
University of California - San Diego
Danger - Unstable Cliffs - Stay Back: The yellow warning signs that pepper coastal cliffs from northern California to the US-Mexico border may seem overly dramatic to the casual observer. But actively eroding cliffs make up the majority of the California coastline, and sudden landslides and collapses have caused injuries and several fatalities in recent years. In addition, eroding cliffs currently threaten highways, houses, businesses, military bases, parks, power plants, and other critical facilities--all in all billions of dollars of development.
