GeoSure Collapsible Ground Hazard Assessment for Great Britain

2026-03-11 updated dataset from the British Geological Survey assesses the potential for rapid ground subsidence due to metastable loessic deposits. It provides complete coverage of Great Britain, based on BGS DiGMapGB-50 mapping and expert geological knowledge. The data informs planning decisions by indicating causes of subsidence from construction loading and water saturation.

Use Cases

• Model construction risk by analyzing the collapsible ground hazard assessment linked to DiGMapGB-50 lithology codes.
• Inform regional planning policies using the complete spatial coverage of Great Britain for metastable deposit identification.
• Correlate historical property damage with the assessed potential for collapse from loaded and saturated loessic material.

Strengths

• Complete spatial coverage of Great Britain.
• Based on authoritative BGS DiGMapGB-50 digital mapping and expert geological knowledge.
• Updated methodology subject to revision with improvements and map code changes.

Limitations

• Specific row count, column structure, and sample data are unavailable for review.
• Primary storage formats are ESRI and MapInfo, which may require specific GIS software for use.
• Assessment focuses on one of six natural geological hazards, not a multi-hazard composite.
