Chance of considerable (MMI = VIII) damaging earthquake shaking in 100 years

This data set portrays the spatial potential for damaging earthquake ground shaking quantified as considerable (MMI = VI) in 100 years. The maps and data are based on the average of the results obtained from peak ground acceleration 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) and site amplification based on the relationships of Seyhan and Stewart (2014). MMI = VIII is equivalent to peak ground acceleration of 0.4g and 1.0-second horizontal spectral acceleration of 0.499g (Worden et al., 2012) for the default site class (Vs30=760 m/s).
