The workshop will honor the lifetime achievements and contributions of Professor Kenji Ishihara to the field of geotechnical earthquake engineering, with the afternoon session of the second day of the workshop entirely devoted to honor Professor Ishihara and hosted by Professor I.M. Idriss (M. EERI, 1972).

Distinguished speakers from the United States, Japan, New Zealand, Europe, and South America will share experiences with liquefaction mitigation, recent major earthquakes, and highlighting the contributions of Professor Ishihara. A one-day short course before the workshop on Tuesday, March 28, is also offered.

Target audience includes geotechnical engineers, engineering geologists, structural engineers, researchers, agencies officials and students. Panel discussions will promote exchange of ideas and clarification.

This workshop will be the second of a series of periodic workshops on the topic of geotechnical earthquake engineering.
