Calaveras Fault. The Calaveras Fault is a major branch of the San Andreas Fault System that is located in northern California in the San Francisco Bay Area. Activity on the different segments of the fault includes moderate and large earthquakes as well as aseismic creep. The last large event was the magnitude 6.2 1984 Morgan Hill event. The shifting of the earth during the quake had offset the fence lines by eight feet or more. On this bright winter day, nearly 100 years after the magnitude 7.8 temblor struck Northern California, Prentice wants to show me one of the last of these original fences still standing.

Fault Activity Map of California (2010) To provide information for those concerned with land use on or near geologic faults in California.Three types of geological hazards, referred to as seismic hazard zones, may be featured on the map: 1) liquefaction, 2) earthquake-induced landslides, and 3) overlapping liquefaction and earthquake-induced landslides. In addition, a fourth feature may be included representing areas not evaluated for liquefaction or earthquake-induced landslides.

Our studies support the conclusion of Niles (2016), who noted that the Neogene section is depositional on granite at the northern tip of the basement high (Fig. S1 in the Supplemental Material 1), but the margins are strike-slip faults that overprint the unconformity. These observations indicate that significant faulting postdates the Neogene ...
