Earthquake Ground Shaking and its Potential Effects in the San Francisco Bay Region for a Repeat of the Great 1906 Earthquake INDEX     Sound: ON / OFF     Part: 1 2 3     Page: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18     <-- BACK     NEXT -->

Thorough estimates of ground shaking require an integrated set of maps predicting parameters needed both for earthquake resistant design and earthquake damage or loss estimates.

Earthquake Resistant Design Parameters needed are: Peak Ground Acceleration Response Spectral Acceleration at 0.3 sec       -- short-period ground motion, most significant for buildings near 3 stories Response Spectral Acceleration at 1.0 sec       -- mid-period ground motion, most significant for buildings over 10 stories Earthquake Intensity Parameters are needed in terms of: Modified Mercalli, Rossi-Forel, or San Francisco scales
