Official state Earthquake Fault Zone maps that govern construction setbacks and disclosure are produced by the California Geological Survey. Historic Ruptures In the last half of the 1800’s, potentially damaging earthquakes (magnitude 6.0 or greater) occurred in the San Francisco Bay Area at an average rate of once every four years.The California Geological Survey’s Earthquake Hazards Zone Application (EQ Zapp) is an interactive map that details the risk of earthquakes and related hazards for different areas of the state. The map is searchable by address, and it maps three main hazard zones: Fault zones. Landslide zones. Liquefaction zones.zone; Whittier Fault zone (Elysian Park structure); and Santa Monica Fault zone. Exhibit 4.6-1, Regional Fault Map, depicts these faults. The intensity of earthquakes is measured, or expressed in terms of two scales. The Richter Scale measures the strength of an earthquake, or the strain energy released, as determined by seismographic observations.The most significant faults within the plate boundary in central and northern California include the San Andreas, San Gregorio-Hosgri, and Hayward-Rodgers Creek fault zones.
