BGS GeoSure: collapsible deposits
The potential for collapsible ground to be a hazard has been assessed using 1:50 000 scale digital maps of superficial deposits.
BGS GeoSure: compressible ground
The potential for compressible ground to be a hazard has been assessed using 1:50 000-scale digital maps of superficial and bedrock deposits.
BGS GeoSure: landslides
The potential for landsliding (slope instability) to be a hazard has been assessed using 1:50 000 scale digital maps of superficial and bedrock deposits. These have been combined with information from the BGS National Landslide Database and scientific and engineering reports.
BGS GeoSure: running sand
The potential for running sand to be a hazard has been assessed using 1:50 000-scale digital maps of superficial and bedrock deposits.
BGS GeoSure: shrink–swell
Many soils contain clay minerals that absorb water when wet (making them swell), and lose water as they dry (making them shrink). Many of us see this in our gardens when the ground becomes cracked during the summer, yet becomes ‘heavy’ in the winter.
BGS GeoSure: soluble rocks
Ground dissolution occurs when water passing through soluble rocks produces underground cavities and cave systems. These cavities reduce support to the ground above and can cause localised collapse of the overlying rocks and deposits.
