Borehole scans

Free search of over a million borehole records.

The BGS Borehole record viewer offers direct, online access to the National Geoscience Data Centre collection of onshore scanned boreholes, shafts and well records.

Earthquake Timeline

Map viewer providing online access to historical earthquake locations by date.

Groundwater levels timeline viewer

Map viewer providing online access to a timeline of monthly groundwater levels across the UK from 1970 to present.

Hydrogeology viewer

The UK Hydrogeology viewer indicates aquifer potential in generalised terms to show high, moderate and low productivity aquifers, plus rocks with essentially no groundwater. The map's 1:625 000 scale data may be used as a guide to the aquifers at a regional or national level, but should not be relied on for local information.

London Earth

The London Earth soil geochemistry viewer displays interactive geochemical maps for a selection of environmentally sensitive elements in Greater London.

Virtual borehole and section viewer

This application allows you to drill virtual boreholes or draw virtual cross-sections through a geological model in three selected areas of the UK; reflecting a range of geological settings.
