Explore public evidence for ground hazards including flooding, landslides, slope instability, subsidence, erosion, peat, clay, karst, seismic and volcanic conditions.
Check available flood and water evidence and distinguish mapped hazard from the absence of a returned record.
Terrain, geology and mapped landslide evidence can reveal factors that may influence slope behaviour.
Geology, soil, groundwater and historical land use can help identify conditions that warrant investigation.
In suitable geological settings, dissolution, cavities and erosion can be important ground processes.
Depending on the country, relevant evidence can include expansive clay, peat and compressible ground, seismic conditions, volcanic processes and contaminated land.
GroundSurf reports the evidence it can find and explains what it may mean. It does not invent a hazard score where the evidence cannot support one.
