Abstract: The stress-based simplified liquefaction triggering procedure is the most widely used approach to assess liquefaction potential worldwide. However, empirical aspects of the procedure were primarily developed for tectonic earthquakes in active shallow-crustal tectonic regimes.
Accordingly, the suitability of the simplified procedure for evaluating liquefaction triggering in other tectonic regimes and for induced earthquakes is questionable. Additionally, the simplified procedure does not account for the mechanisms of liquefaction triggering and surface manifestation in a consistent and sufficient manner. Specifically, an artifact of the way simplified triggering curves have traditionally been developed is that they inherently include some factors
that influence surface manifestations, particularly for medium dense to dense soils. As a result, using the simplified triggering curves in conjunction with the surface manifestation models results in the double-counting, omission, or general obscuration of distinct factors that influence triggering and manifestation. This presentation highlights some ongoing efforts to address these shortcomings in the simplified liquefaction triggering procedure and also briefly presents some
other research efforts by the presenter regarding liquefaction triggering and surficial manifestation.


Speaker Biography: Dr. Russell Green is a Professor of Civil Engineering at Virginia Tech, Blacksburg, VA, in the Geotechnical Engineering Program area. He was previously on the faculty at the University of Michigan and has held visiting faculty positions at Chuo University, Tokyo, Japan, the University of
Canterbury, Christchurch, New Zealand, and the University of Auckland, Auckland, New Zealand. The primary focus of Russell’s research is in the areas of geotechnical earthquake engineering, and soil and site improvement. He has participated in post-earthquake investigations in the US, Iceland, Haiti, Japan,
and New Zealand, and holds two US patents related to liquefaction mitigation measures. Russell received his bachelor’s
degree in civil engineering from Rensselaer Polytechnic Institute, his master’s degree from the University of Illinois at UrbanaChampaign, and his PhD from Virginia Tech. Russell is a registered professional engineer in Virginia and a veteran of the United States Marine Corps. Also, Russell is the recipient of the
2016 ASCE Norman Medal and was elected to the grade of Fellow in ASCE in 2021, among other awards for research and teac
