The information platform of the Swiss geology community

Tectonics / Structural geology

Enormous forces have always been at work inside our Earth. They continuously deform the Earth’s crust and affect its structural composition. Tectonic maps show how Switzerland is geologically constructed (© swisstopo).

Geotechnics & engineering geology

Geotechnical engineering combines elements of earth science, construction and mining. Tunneling projects, slope stabilization or site investigations are typical areas of application (© AlpTransit Gotthard AG).

Boreholes

Boreholes provide information about the composition of the ground. They also serve a particular purpose: for example, for the production of natural gas or as preparation for construction methods (© BGS, P001441).

Geological hazards

Nature is beautiful - but it can also be dangerous: Natural phenomena, which have causes in the Earth’s interior or near the surface of the Earth, can result in natural disasters. Examples include volcanoes, earthquakes, landslides and floods (© PLANAT).
