Summary

[edit]
Description This photo shows an oblique aerial view of the Lower Van Norman Dam, overlooking the heavily populated San Fernando Valley​. It was taken after the ​February 9, 1971, San Fernando Earthquake ​ ​and d​emonstrat​es​ the vulnerabilit​y​ of the modern urban society to the damaging effects of a nearby earthquake. The dam was damaged nearly to catastrophic failure when part of the hydraulic-fill embankment and the concrete lining slid into the reservoir. About 80,000 people living downstream from the dam had to be evacuated as a precautionary measure. Photo by J. I. Ziony. Los Angeles County, California. 1971.
