Seismic Risk Analysis of Major Natural Gas Infrastructure <\/h2>\n\n\n\n
\n
\n

This is a large research initiative involving multiple universities and practicing professionals to develop probabilistic seismic hazard analyses for fault displacement hazard, landslide, and liquefaction hazards; develop a very large and comprehensive database of fragilities of major natural gas infrastructure; and to carry out seismic risk analysis of natural gas infrastructure at the state-wide California.<\/p>\n<\/div>\n\n\n\n

Effects of Fault Rupture Directivity for Probabilistic Seismic Hazard Analysis of Infrastructure<\/h2>\n\n\n\n

Multiple directivity models are directly incorporated into probabilistic seismic hazard analysis (PSHA). This is the first time that that a combination of NGA-West2 and directivity models is directly merged with a very complex fault system to carry out PSHA. The analyses are carried out at over 19,000 sites in California and the first directivity-based PSHA map for the State is developed.<\/p>\n\n\n\n
