Geological Collapsibility Hazard Assessment from BGS

An assessment of the potential for geological deposits, typically loess or loessic material, to collapse under critical load. The methodology is based on British Geological Survey digital stratigraphic linework and expert knowledge of formation behavior.

Use Cases

• Map collapsibility risk using digital stratigraphic linework and expert-defined formation behavior
• Identify areas with loessic material deposits prone to subsidence under load
• Support geotechnical planning by integrating hazard assessments based on geological formations

Strengths

• Methodology is based on authoritative BGS digital stratigraphic linework
• Incorporates expert knowledge of geological formation behavior
• Focuses on a specific natural hazard (collapsibility) relevant to engineering

Limitations

• Specific data volume, column structure, and sample records are unavailable for review
• The original dataset is noted as no longer existing, now part of a broader system (GeoSure), which may affect direct accessibility
