Every aspect of geotechnical safety, reliability and risk will be covered. This includes both theoretical developments and practical applications for a wide range of geotechnical related problems. Topics include but are not limited to: (1) Geotechnical uncertainty and variability (2) Geohazards, such as landslides, earthquakes, tsunami and climate changes (3) Reliability and risk analysis (4) Reliability-based design and limit state design in geotechnical engineering (5) Risk assessment and management in geotechnical engineering and infrastructural projects (6) Practical applications and case studies
