Earthquake Shaking Potential for California
"This map shows the expected relative intensity of ground shaking and damage in California from anticipated future earthquakes. The shaking potential is calculated as the level of ground motion that has a 2% chance of being exceeded in 50 years, which is the same as the level of ground-shaking with about a 2500 year average repeat time. Although the greatest hazard is in areas of highest intensity as shown on the map, no region is immune from potential earthquake damage. Expected earthquake damage in California in the next 10 years exceed $30 billion.

High frequency shaking potential: Earthquake shaking at 0.2 second period affects short, stiff structures and is also used in estimating future earthquake damage. Local soil conditions have less effect on high frequency shaking, so this map shows less influence of the surface geologic materials map."
