Canyon Landslide in Laguna Beach, California was reactivated in March 1978
following several years of severe drought. Homes were unknowingly constructed
upon the ancient

Collapse
of California Route 1 bridges across Struve Slough in Monterey County, which
occurred
during the October 1989 Loma Prieta earthquake. The channel was filled
with 300 feet of soft estuarine
clay which magnified the shaking intensity, causing the supporting caissons
to snap off, puncturing the
bridge deck as it collapsed.
