Fig. 4From: Seismic Hazard Function (SHF) study of coastal sources of Sumatra Island: SHF evaluation of Padang and Bengkulu citiesSeismic hazard maps expressed as the PGA of 10% of exceedance probability in 50 years. The total exceedance probability is calculated on the basis of selected sources within a radius distance of about 100 km along the Sumatran Subduction Zone for events with a magnitude range of 6.0 to 9.0. In calculating PGA, the parameters of influence are the changes in the magnitude and distance of source which are based on the GMPE of ZH97 and AT06 and the calculated mean PGABack to article page
