Fault system that produced 6.0 quake poses big dangers
While much of California’s earthquake risk has been historically focused on the San Andreas fault and places like Los Angeles and San Francisco, quakes are capable of causing significant destruction in the state’s Sierra Nevada and Sacramento-San Joaquin Delta … UCLA experts warned in 2014 that a major earthquake sending destructive shaking to the Sacramento-San Joaquin Delta could potentially destroy aging levees, causing flooding and drawing in saline water from San Francisco Bay — which would contaminate one of the state’s key water supply systems.
