February 9, 1971, San Fernando Earthquake. Demonstrating the vulnerability of the modern urban society to the damaging effects of a nearby earthquake. Oblique aerial view of collapsed highway over- passes and bridges at the interchange of the Foothill and Golden State Freeways. Because the earthquake occurred early in the morning, only three deaths resulted from this damage. However, the principal highway link between northern and southern California was temporarily cut, and traffic had to be re-routed for several months. See also California Earthquake image 005. Photo by R. E. Wallace. Los Angeles County, California. 1971. Published in U.S. Geological Survey Professional Paper 1360 as Figure 2-B. 1985.
