‘The Santa Clara Valley Water District has received preliminary findings from an ongoing seismic stability evaluation for Anderson Dam that detail part of the dam could experience “significant slumping” if a 7.25 magnitude earthquake were to occur on the Calaveras Fault within about a mile of the dam.’ [Source: MorganHillTimes.com via Association of State Dam Safety Officials]
