Research Projects (Selected)
GeoHazard Research Program
There are multiple research projects under this program including: Non-Ergodic Ground Motion Models, Next Generation of Ground Motion Model for Crustal Earthquakes (NGA-West3), Ground Motion Models Considering Inelastic Structural Response, among others.
Funded by:
California Department of Transportation (Caltrans) and Pacific Gas & Electric Company (PG&E)
Seismic Risk Analysis of Major Natural Gas Infrastructure
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.
Funded by:
California Energy Commission (CEC), Pacific Gas & Electric Company (PG&E), and Sothern California Gas Company
Fault Displacement Hazard Initiative (FDHI)
A large community-based research program involving multiple universities and practicing professionals, to develop fault displacement database and multiple new fault displacement models. Additionally, for the first time, a probabilistic fault displacement hazard map for the State of California is developed.
Funded by:
California Energy Commission (CEC), California Department of Transportation (Caltrans), Pacific Gas & Electric Company (PG&E), Sothern California Gas Company, Los Angeles Department of Water and Power, and California High-Speed Rail.
Seismic Risk Analysis of Major Water Transmission Infrastructure
Quantification of seismic risk for water transmission infrastructure including the effects of ground shaking and fault displacement hazards.
Funded by:
Los Angeles Department of Water and Power
Next Generation Ground Motion Models for Subduction Earthquake
A large community-based research program involving multiple universities and practicing professionals, to develop database, multiple new ground motion models, and computer tools for Subduction Events (NGA-Sub). The project was recently completed, multiple reports and journal papers are being published.
Funded by:
FM Global, USGS, California Department of Transportation (Caltrans) and Pacific Gas & Electric Company (PG&E)
Seismic Performance of a Smart City
Analyze recorded ground motions and structural response in an area with a very dense network of seismic sensors. This is a collaborative international program involving multiple countries.
Funded by:
The US National Science Foundation (NSF)
Analysis of Natural Gas Transmission System Subjected to Ground Subsidence
Analyze a major natural gas pipelines subjected to gradual soil subsidence.
Funded by:
Southern California Gas Company
Effects of Fault Rupture Directivity for Probabilistic Seismic Hazard Analysis of Infrastructure
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.
Funded by:
California Energy Commission (CEC), California Department of Transportation (Caltrans) and Pacific Gas & Electric Company (PG&E)
Effects of Kappa on Ground Motions
Quantification of the effects of Kappa on high-frequency ground motions.
Funded by:
Electric Power Research Institute (EPRI), Électricité de France, and Pacific Gas & Electric Company (PG&E)
Damping Scaling Model for Subduction and Stable Continental Regions
Developing damping scaling model for NGA-Sub and NGA-East, and also based on data collected in France.
Funded by:
USGS, and Électricité de France
