Seismic behaviour of geotechnical structures-Past, present and future

This paper begins with the background of earthquake geotechnical engineering history divided in 4 periods. The performance based seismic design is addressed and after a brief introduction to earthquake hazard the topics slope stability, potentially liquefiable soils, earth retaining structures, soil-structure interaction, embankment dams, underground structures, solid waste landfills are discussed. The topics that deserve more consideration and can be considered new challenges are pointed out. Finally my vision and lessons for tomorrow are presented.
