The shaking demands experienced during the Napa M6.0 earthquake are approximately 60-90% of the demands used for the design of new buildings. The chart to the right includes the shaking demands expected for earthquakes that occur on average every 475 and 2475 years. New buildings are generally designed for an earthquake corresponding to the 475-year level.
If you have questions about the shaking demands corresponding to your building’s location or the shaking intensity of your area, please contact Russell Berkowitz.
