Rockfall hazard assessment of the Stawamus Chief using multi-temporal remote sensing analysis

The Stawamus Chief in Squamish, British Columbia, represents a significant geological feature with recognized rockfall hazards. This thesis investigates rockfall hazards within Stawamus Chief Provincial Park, focusing on two major events in 2021. Employing advanced remote sensing techniques, including LiDAR, photogrammetry, and infrared thermography, the study characterizes pre- and post-failure slope morphology in affected areas. Integrating newly acquired data with existing data sets enables detailed analysis of rockfall source zones. Future rockfall hazards are evaluated through structural lineament analysis, historical runout mapping, and climbing route assessments using the Rockfall Susceptibility Index (RSI). By combining historical observations with state of the art remote sensing and qualitative hazard analysis, this research enhances understanding of rockfall hazards, crucial for ensuring the safety of visitors to the park. The study emphasizes the necessity of proactive measures in managing and mitigating rockfall hazards, contributing to the sustainable enjoyment of recreational areas like Stawamus Chief Provincial Park.
