Presented by Dr. Alan Hull, Golder
We are working through our Annual Conference speakers bringing their prepared presentations to you via webcas t. Dr. Hull was scheduled to present this topic at our Annual Conference th is past April that was unfortunately cancelled due to the COVID-19 pandemic .
It is almost 50 years since the California Legislature passed the A
lquist-Priolo Earthquake Fault Zoning Act in response to the damage from th
e 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 have developed standards and
guidelines to try and mitigate the effects of both strong shaking and surfa
ce fault rupture on seismically active faults. In parallel, science has gre
atly increased our understanding of the earthquake source mechanics, source
-to-site path and shallow soil effects, and the ways to capture uncertainti
es into predictive models.
This presentation will use examples from th
e western USA and California to illustrate how earthquake and related hazar
ds are incorporated into every-day engineering projects.
Following a brief summary of earthquake fundamentals, illustrated examples will explore how earthquake ground motions are quantified, and then captured into proje ct design criteria, including how uncertainties can be incorporated into pr obabilistic and deterministic analyses. Examples will show the variety of r egulatory approaches used within and beyond California; and explore the nee ds of engineers and regulators from ongoing scientific inquiry.
Dr. Alan Hull is a Senior Practice Leader at Golder Associates in Portland, OR. Alan is a California-registered engi neering geologist who focuses on paleoseismology, earthquake hazard assessm ent and incorporating the effects from seismically active faults into engin eering analysis and design. Prior to joining Golder, Irvine CA in 2001, Ala n spent 20 years with the New Zealand Geological Survey (now GNS Science) u ndertaking basic and applied paleoseismic research from 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 a nalyses (PSHA); and the engineering geology at sites in Africa, Asia, Centr al America, Europe, North and South America; and the South Pacific. Alan ha s 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 Geoscienc e Practitioners for Assessing Fault Rupture Hazards in California.
