Surface Fault Rupture Hazards: Engineering and
Community Response

Guest Speaker: Dr. Alan Hull, CEG (Golder)

It is almost 50 years since the California Legislature passed the Alquist-Priolo Earthquake Fault Zoning Act in response to the damage from the 1971 San Fernando earthquake and surface fault rupture. While California’s strict zoning and regulatory responses have not been replicated elsewhere in the world, governments and key industries worldwide have developed standards and guidelines to try and mitigate the shaking and surface rupture hazards posed by tectonically active faults. In parallel, science has greatly increased our understanding of the coseismic faulting process, developed new measures for the intensity of earthquake shaking, and importantly, ways to capture uncertainties into predictive models.

This presentation uses examples from around the world to illustrate ways the mining, oil and gas and pipeline industries approach to the potential impact of surface fault rupture and related hazards in engineering risk analyses. Examples will explore how faults at sites from both seismically active and quiescent areas are evaluated, and how the results, including uncertainties, are incorporated into probabilistic and deterministic models. Case studies will show the variety of regulatory approaches used within and beyond California; and to explore the needs of engineers and regulators from ongoing scientific inquiry.

Speaker Bio: Dr. Alan Hull, CEG

Dr. Alan Hull is a Senior Practice Leader at Golder Associates in Portland OR. Alan is a California-registered engineering geologist who focuses on paleoseismology, earthquake hazard assessment and incorporating the effects from seismically active faults in engineering analysis and design. Prior to joining Golder in 2001, Alan spent 20 years with the New Zealand Geological Survey (now GNS Science) undertaking basic and applied paleoseismic research, including fault trenching and marine terrace studies. His consulting assignments for mining, oil and gas, government, and utility clients have been to understand and quantify the hazards from potentially seismogenic faults, probabilistic seismic hazard analyses (PSHA); and the engineering geology at sites in Africa, Asia, Central America, Europe, North and South America; and the South Pacific. Alan has authored more than 50 peer-reviewed journal articles and numerous client-focused reports. Alan was a member of the 2016-2018 Expert Panel supporting the update of California Geological Survey SP 42– Earthquake Fault Zones: A Guide for Government Agencies, Property Owners/Developers, and Geoscience Practitioners for Assessing Fault Rupture Hazards in California.
