Probabilistic Seismic Hazard Analysis - Composite shaking hazard across the Bay Area based on all earthquake scenarios and probability information using the Modified Mercalli Intensity (MMI) scale. Shows likely shaking intensity in the Bay Area in any 50 year period from all possible faults. A 10% in 50 years probability was chosen as it most closely aligns with current building standards in the California Building Code.
Earthquakes - Liquefaction
Liquefaction Hazard Areas - liquefaction hazard areas mapped by the California Geological Survey
Earthquakes - Faults
Wildfire Threat - wildland fire threat to human development
Fire Perimeters - extents of previous wildfires in the San Francisco Bay Area
Debris Flow Source Areas - debris flow source areas for rainfall/storm induced landslides
Landslide Hazard Areas - earthquake induced landslide hazard areas mapped by the California Geological Survey
