DrQuigs Geological Hazards Consulting has global expertise in the analysis of geological hazards including fault rupture, strong ground shaking, liquefaction, rockfalls, and landslides. We are one of the world’s leading university-based research providers in seismic source characterization and seismic hazard, as evidenced from our research publications. We have extensive experience in the communication of complex science to stake-holders and government. We also review technical scientific reports in earthquake hazards, seismic hazard analysis, engineering geology and geotechnics.
