GeoSure Collapsible Deposits: Ground Subsidence Hazard Map for Great Britain

Great Britain is covered by this dataset assessing the potential for geological deposits to collapse due to metastable loessic material. The British Geological Survey created it based on their 'BGS Geology' digital map and expert knowledge, with data last updated in April 2026. It models the risk of rapid ground subsidence when such material is loaded and saturated.

Use Cases

• Risk assessment for construction projects based on modeled ground collapse potential.
• Informing planning decisions based on natural geological hazard information.
• Investigating causes of property subsidence based on geological deposit behavior.

Strengths

• Provides complete spatial coverage of Great Britain.
• Methodology is based on authoritative 'BGS Geology' digital mapping and expert knowledge.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data scale are unknown, which may limit suitability assessment.
