NHERI mobile shakers help researchers mitigate soil liquefaction

On this episode of Designsafe Radio, we speak with Arash Khosravifar, an assistant professor in the civil and environmental engineering department at Portland State University. Khosravifar explains his research on soil liquefaction, his experience researching with the NHERI mobile shaker trucks and the team from the University of Texas, Austin, and the new research he has been participating in called Microbially Induced Desaturation (MID). MID is specifically important research for the cities located in the Cascadia Subduction Zone and the “critical infrastructure energy hub” located in Portland, Oregon. Check out the following links for more information on the topics discussed on this podcast episode: Khosravifar’s NSF Grant Award 1935670: https://www.nsf.gov/awardsearch/showAward?AWD_ID=1935670&HistoricalAwards=false Soil Liquefaction Prevention Technique Turns in Promising Performance (published 7/24/2020) : https://intheloop.engineering.asu.edu/2020/07/24/soil-liquefaction-prevention-technique-turns-in-promising-performance/ Possible affected regions of Cascadia Subduction Zone: https://www.pnsn.org/blog/2020/01/27/getting-ready-for-the-next-great-cascadia-subduction-zone-earthquake Collaborative Research Boosts Resilience in Cascadia Subduction Zone link: https://www.designsafe-ci.org/community/news/2020/june/collaborative-research-boasts-resilience-cascadia-subduction-zon/ Designsafe Quarterly Newspaper Summer 2020: https://www.designsafe-ci.org/media/filer_public/bb/bb/bbbb4eb6-f7cc-4a54-9d37-9a69dde5e2d9/nheri_quarterly_issue_11_-_june_2020_v2.pdf Articles including Khosravifar's research: 1. https://scholar.google.co.in/citations?user=sfZGJNAAAAAJ&hl=tr 2. https://works.bepress.com/arash-khosravifar/ 3. https://utexas.designsafe-ci.org/projects/Cascadia Subduction Zone and cities/states it could affect: https://www.pnsn.org/blog/2020/01/27/getting-ready-for-the-next-great-cascadia-subduction-zone-earthquake The Centrifuge at University of California, Davis: https://cgm.engr.ucdavis.edu/facility/9-m-centrifuge
