Figure 38.
Damage at the Lower Van Norman Dam by the February 9, 1971, San
Fernando, California,
earthquake; view to the east. A massive slide into the reservoir
broke off the east outlet tower and
damaged the west outlet tower (foreground). No water overtopped
the dam, and no leaks developed as a
result of the shaking. More than 75,000 residents were evacuated
from the area downstream for 3 days
after the earthquake. (Photo by G. W. Thorsen)
