RAS Webinar: Rail Recovery after Earthquakes: From Engineering and Stakeholder Insights to Transportation Decisions

The next Railway Application Section (RAS) 𝘄𝗲𝗯𝗶𝗻𝗮𝗿 will take place on Thursday, September 24, 04pm - 05pm CET. For this live webinar, RAS invites Tianyu Han from the University of California, Berkeley to talk about his work on Rail Recovery after Earthquakes: From Engineering and Stakeholder Insights to Transportation Decisions

𝗜𝗻𝘁𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝘁𝗼 𝘁𝗵𝗶𝘀 𝗧𝗮𝗹𝗸:

Earthquakes can disrupt critical rail links, reduce regional mobility, and place pressure on substitute roads and transit services. Restoring service requires not only repairing physical damage but also coordinating inspections, operating restrictions, replacement buses, personnel, staging, and public information. This webinar will explore these connected challenges through BART's Berkeley Hills Tunnel in the San Francisco Bay Area, a single critical rail link that intersects the Hayward Fault. The webinar will show how tunnel damage is translated into operating and restoration scenarios, how disruptions affect cross-hills mobility, and why strategies such as bus bridges depend on institutional resources and coordination. The findings and analyses are built upon detailed tunnel analysis developed by UCLA engineers, multimodal transportation modeling at UC Berkeley, and interviews with BART, Caltrans, and regional agencies. The webinar will address actionable insights for scenario planning, interagency preparedness, and implementable recovery strategies.

Tianyu Han is a PhD candidate in Civil and Environmental Engineering at the University of California, Berkeley. His research focuses on the risk, resilience, and recovery of urban infrastructure systems exposed to natural hazards, including transportation networks and buried water and gas pipelines. Through his work with the NHERI SimCenter and collaborations with government agencies and engineering consulting firms, he has contributed to a range of infrastructure resilience projects. His work combines engineering analysis, probabilistic risk assessment, infrastructure and network modeling, and decision support to improve preparedness and recovery planning.
