Earthquake Probabilities and Hazard Maps

WEB SITES

• National Quaternary Fault & Fold Database
- information on faults and associated folds in the United States that are believed to be sources of M>6 earthquakes during the Quaternary (the past 1,600,000 years). Maps of these geologic structures are linked to detailed descriptions and references.

• National Seismic Hazard Maps
- National maps of earthquake shaking hazards provide information essential to building codes used in the United States.

• Global Seismic Hazard Map

• Predictive Intensity Maps
- Predicting the intensity of shaking due to an earthquake before the earthquake occurs.

• Shaking Hazard Maps
- Ground motion expected for various possible earthquakes in the San Francisco Bay area from the Association of Bay Area Governments.
