Transportation Seminars at Portland State University have been a tradition since 2000. Formerly known as the Friday Transportation Seminar series, we've opened up PSU Transportation Seminars to other days of the week to better accommodate attendance. You can always watch online via Zoom.



The Kahramanmaras earthquakes struck Turkiye and Syria on February 6th 2023 causing widespread damage and loss of life. Following the earthquakes, the Geotechnical Extreme Event Reconnaissance (GEER) Association deployed teams to survey damage and collect perishable data on damage to infrastructure related to geotechnical earthquake damage. This presentation describes some of the findings from these reconnaissance activities, focusing on damage to transportation infrastructure and cases that apply to earthquake hazard planning and engineering in the Pacific Northwest.


  • Geotechnical earthquake hazards, including liquefaction and slope failures, can damage transportation infrastructure
  • Movement of people and goods can be limited by geotechnical earthquake damage, including damage to ports, damage to roads and bridges, flooding, and ejecta
  • Liquefaction of reclaimed land and plastic soils was documented in Turkiye and is a significant concern in the Pacific Northwest


Diane Moug, Assistant Professor, Civil & Environmental Engineering, Portland State University

Diane Moug is an Assistant Professor in the Civil and Environmental Engineering department at Portland State University. Her research aims to reduce geotechnical earthquake hazards through improved hazard characterization in poorly-understood soils and innovative mitigation. She is particularly focused on the earthquake hazards of the Pacific Northwest’s fine-grained silty soils and at the Critical Energy Infrastructure hub in Portland, Oregon. She also investigates liquefaction mitigation through microbially induced desaturation. Diane teaches courses on introductory and advanced soil mechanics, computational geomechanics, and geotechnical site investigation. She earned a Masters and PhD in Civil Engineering at the University of California, Davis, and a Bachelor’s of Applied Science in Geological Engineering at the University of British Columbia. As a member of EERI, Diane is currently a Co-Chair of the Younger Members Committee. She is a past Co-President and Treasurer of the Student Leadership Committee.


This 60-minute seminar is eligible for 1 hour of certification maintenance credit, for those who track professional development hours.



Portland State University's Transportation Research and Education Center (TREC) is home to the U.S. DOT funded National Institute for Transportation and Communities (NITC), the Initiative for Bicycle and Pedestrian Innovation (IBPI), PORTAL, BikePed Portal and other transportation grants and programs.
