Summary
These maps and data portray the spatial potential for damaging ground shaking quantified as slight (MMI ≥ VI), moderate (MMI ≥ VII), and considerable (MMI ≥ VIII) in 100 years. The maps and data are based on the average of the results obtained from pga and 1.0-second horizontal spectral acceleration. Site specific soil factors based on Vs30 shear wave velocities were implemented using a simple topographic proxy technique (Allen and Wald, 2009). Allen, T.A. and Wald, D.J. 2009,. On the use of high-resolution topographic data as a proxy for seismic site conditions (VS30), Bulletin of the Seismological Society of America 99, 935-943.
