Introduction to Shaking
Hazard Maps
Shaking
Hazard Maps - San Francisco Bay Area
Maps of predicted shaking intensity for various possible earthquakes
in the San Francisco Bay area, expressed on the Modified Mercalli
Intensity Scale. This site from the Association of Bay Area Governments
(ABAG) offers a variety of resources on ground shaking, how
it is estimated, and what effects it may have.
Shaking
Intensity Maps - San Francisco Bay Area
More maps of predicted shaking intensity in three "scenario"
San Andreas fault and Hayward fault earthqukes.
Effect of Soil Type
on Shaking Hazard
The type of soil at a site affects the intensity of shaking there.
Learn about this effect and use interactive maps to look up the
soil type at any site in the San Francisco Bay Area.
Liquefaction Hazard and
Shaking Amplification Maps for Alameda County
Digital database identifying areas in the Oakland,
California region that could produce surface liquefaction and amplify
ground shaking from earthquakes.
When
Will the Next Great Quake Strike Northern California?
The Great 1906 San Francisco Earthquake is the most powerful
in Northern California's recorded history. New studies of this earthquake
are yielding important clues we can utilize to better prepare for
future earthquakes.
Potential for Large Earthquakes
in Northern California
Report by the 1996 Working Group on Northern California Earthquake
Potential (Open-File Report 96-705). Downloadable map and database
of active faults in Northern California.
Predicted
Shaking for a Repeat of the Great 1906 Earthquake
Automated slide show (15 minutes) reviewing the 1906 and 1989 earthquake
damage, the application of GIS technology, and expected ground shaking
maps for the San Francisco Bay Region.
Recent
and Significant Past Earthquakes
Index of large or otherwise important earthquakes of the past (U.S.
and global) for which photographs and reports are availble online.

Cone Penetration Testing (CPT) is used to infer soil type
and liquefaction susceptibility in the upper hundred feet of the
Earth's crust. Download USGS CPT data here.

adjustments to these risks, by the national Hazards Center at the
University of Colorado, Boulder.
Hazards in Perspective
Floods, earthquakes, tsunamis, volcanoes, landslides, wildlife disease,
