Great Britain ground stability data from the British Geological Survey identifies areas susceptible to six specific geohazards at a 1:50,000 scale. The dataset, version 8, assesses processes including shrink-swell clays, landslides, and running sands. It was last updated in March 2026.
Use Cases
- Map regional susceptibility to shrink-swell clay hazards for property foundation risk assessment.
- Analyze landslide (slope instability) susceptibility to inform infrastructure planning and development.
- Identify areas with compressible ground or collapsible deposits to evaluate construction site suitability.
- Model dissolution risk in soluble rocks to assess potential for underground cavity development.
- Assess running sand hazard zones for groundwater flow and subsurface stability studies.
Strengths
- Covers six distinct and well-defined geohazard processes for systematic analysis.
- Provides national-scale coverage for Great Britain at a consistent 1:50,000 mapping scale.
- Maintained by the authoritative British Geological Survey (BGS) with a March 2026 update.
Limitations
- Specific data volume (row/column counts), sample data, and file formats are not provided.
- The analysis is at a regional scale (1:50,000), which may not capture local site-specific variations.
- License terms for use and redistribution are unknown.
