CPT-Based Liquefaction Case Histories Compiled from Three Earthquakes in Canterbury, New Zealand

July 21, 2021 | 1:00pm - 2:00pm CT

About the Webinar

Earthquakes occurring over the last decade in the Canterbury region of New Zealand have resulted in liquefaction case-history data of unprecedented quantity. This provides the profession with a unique opportunity to advance the prediction of liquefaction occurrence and consequences. Towards that end, this presentation discusses a curated digital dataset of ~15,000 cone-penetration-test-based liquefaction case histories compiled from three earthquakes in Canterbury.

The post-processed data is presented in a dense array structure, allowing researchers to easily access and analyze a wealth of information pertinent to free-field liquefaction response (i.e., triggering and surface manifestation). Research opportunities using this data include, but are not limited to, the training or testing of new and existing liquefaction-prediction models.

The many methods used to obtain and process the case-history data will be summarized, along with the structure of the compiled digital file. Lastly, numerous recommendations for analyzing the data will be discussed, including nuances and limitations that users should carefully consider.

About the Presenter

Brett Maurer is an Assistant Professor of Civil & Environmental Engineering at the University of Washington (UW). Maurer received his B.S. and M.S. degrees from Syracuse University in 2009 and 2011, respectively, and his PhD from Virginia Tech in 2016. Maurer teaches courses focused on foundation engineering, retention structures, soil dynamics, and geotechnical earthquake engineering, among others. Maurer's commitment to education and teaching has been recognized by the UW CEE Department via an Outstanding Teaching Award and by the UW College of Engineering via a Faculty Appreciation for Career Education and Training Award. Maurer’s primary research focus is geotechnical earthquake engineering, including soil liquefaction, paleoseismology, life-cycle hazard mitigation, seismic site characterization, machine and deep learning, remote sensing, and post-earthquake investigation.

Maurer has received several research awards including: the ASCE Norman Medal; a National Science Foundation CAREER Award; an Early Career Researcher Award from the US Council on Geotechnical Education and Research; and a NHERI DesignSafe Outstanding Dataset Award. Maurer currently serves as Associate Editor for Earthquake Spectra and is a member of the ASCE Technical Committee on Soil Dynamics and Earthquake Engineering.
