Enhancement of National Seismic Hazard Maps
• Updating data is based upon the latest studies such as recent active-fault studies utilizing trenching,
carbon dating, epicenter relocation, strain analysis (GPS) as well as availability of basic data
including the SRTM-30, IFSAR, LiDAr, and earthquake catalog up to 2016.
• Considering the latest GMPE published after Tohoku earthquake and latest NGA. • EHB (1960-2008)
All Shocks (1907-2016): • USGS (1973-2016)
• Adding OpenQuake software for comparison and verification to USGS and EZFRisk software. • ISC-GEM (1907-2004)
• Relocated BMKG data (2009-2015)
