Electronic Supplement to
Ground Motion Modeling of the 1906 San Francisco Earthquake I: Validation Using the 1989 Loma Prieta Earthquake

by Brad T. Aagaard, Thomas M. Brocher, David Dolenc, Douglas Dreger, Robert W. Graves, Stephen Harmsen, Stephen Hartzell, Shawn Larsen, and Mary Lou Zoback

Synthetic versus Broadband Instrumental Intensities

Comparison of long-period and broadband synthetic intensities with broadband instrumental intensities.

Broadband instrumental ShakeMap for the 1989 Loma Prieta earthquake. The star identifies the epicenter, the thick black lines delineate the projection of the fault plane in the Wald source model, and the triangles show locations of the stations used in the construction of the ShakeMap.

Broadband instrumental ShakeMap

Synthetic ShakeMaps for Aagaard's (T > 2.0 s) simulations of the Loma Prieta earthquake with the Beroza and Wald source models. The lower panels show the differences between the synthetic ShakeMaps (top panels) and the broadband instrumental ShakeMap.

Synthetic ShakeMaps for Dolenc et al.'s (T > 1.25 s) simulations of the Loma Prieta earthquake with the Beroza and Wald source models. The lower panels show the differences between the synthetic ShakeMaps (top panels) and the broadband instrumental ShakeMap.
