Three JPEG Images Showing the Active Faults Referred to in the Text

Figure ESupp 1. Hazardous faults in the Wellington, New Zealand region. Faults listed in Table 1 are identified. The site where the deaggregation is performed is shown as a star and is labeled Wellington. All faults have surface traces except the Hikurangi subduction zone (9), which dips north-westwards under Wellington. The background map depicts probabilistic 1-s spectral acceleration for the 2% in 50 year probability of exceedance, using the 2007 New Zealand Seismic Hazard Model (Stirling et al., 2007) and stiff soil site condition (Standards New Zealand 2004).

Figure ESupp 2. Hazardous faults in the Christchurch, New Zealand region. Faults listed in Table 2 are identified. The site where the deaggregation is performed is shown as a star and is labeled Christchurch. All faults have surface traces .The background map depicts probabilistic 1-s spectral acceleration for the 2% in 50 year probability of exceedance, using the 2007 New Zealand Seismic hazard Model (Stirling et al., 2007) and stiff soil site condition (Standards New Zealand 2004).

Figure ESupp 3. Hazardous faults in the Los Angeles, California region (see Table 3). Faults that rupture to the surface are blue, while blind thrusts, which are several km deep, are brown. PH= Puente Hills. The Puente Hills fault either ruptures as three independent segments or as a connected fault. The site where the deaggregation is performed is shown as a star and is labeled LA Site. The background map depicts probabilistic 1-s spectral acceleration from the most recent U.S. national seismic hazard map update (Petersen et al., 2008), for the 2% in 50 year probability of exceedance, and rock site condition (vs30 = 760 m/s).
