Past geological events such as slope failures and faulting leave distinct traces across a landscape.
When hazards are identified early in a project, the risks created by these hazards can be fully investigated as part of the initial design stage and practical solutions can then be implemented to minimise their impact.
Hazards can be identified in a number of ways. Geological maps give an indication of the rock types present and any known faults in an area. Aerial photographs can also be examined for geomorphological features such as land slide scarps, colluvium lobes, fault scarps and areas of swampy ground. A site walkover inspection can further identify geomorphology features than cannot be seen in the desk study information.
