2nd Kenji Ishihara Colloquium Series on Earthquake Geotechnical Engineering

“Seismic Lateral Displacements”

Thursday & Friday, August 22-23, 2019
San Diego State University
San Diego, CA

The second of this colloquium series, honoring Professor T. Leslie Youd, will focus on seismic lateral displacements and will take place at San Diego State University on Thursday & Friday, August 22-23 from 8am to 5pm. The topics that will be presented on during the colloquium are oriented towards geotechnical engineers, structural engineers, engineering geologists, architects, civil engineers, researchers, and students. 22 speakers, consisting of geotechnical and structural engineers, set to present at this colloquium include Prof. T. Leslie Youd, Prof. Kenji Ishihara, Prof. Thomas O’Rourke, Prof. Liam Finn, Prof. Jonathan Bray, Prof. Masanori Hamada, and other engineers and professors from the United States, Canada, Japan, Mexico, and Chile.

Registration includes breakfast, lunch, and refreshments during the breaks.
