What are geohazards? Geohazards in PanGeo are natural and man-made
phenomena that make the ground unstable.
PanGeo geohazards include: – Earthquakes
– Slope instability (landslides)
– Mineral workings (past & present)
– Groundwater abstraction & recharge
– Shrink and swell clays
– Soluble rocks
– Compressible ground
– Collapsible deposits
– Landfill
Risks from geohazards are increasing as cities become bigger.
Geohazards cost the EU hundreds of lives and billions of Euros each year.

Users of geohazard information
10
Local Authorities: Responsible for development and planning control
Protect and maintain infrastructure
Protect key buildings (control centres, hospitals, schools, etc.)
Responsibility for public safety
Policies could be influenced by geohazards
Often involved in property conveyancing
National Geological Surveys: Mandated to collect, store, and make-accessible data on geohazards
Mandated to advise government on geology and geohazards
National repository of geohazard information
PanGeo helps standardise data across Surveys – supporting EC initiatives
Policy-makers: Statistical analysis of European geohazards
Measures of population-exposure
Improved preparedness in civil protection
Regional planning and regulation
Policy formulation
public Better-informed
Better prepared
Utility in conveyancing
Empowerment
Service Overview
• Establish an INSPIRE-compliant, free, online Geohazard information service for 52 of the largest towns in EU27.
• Add value to the GMES Urban Atlas by adding a Geohazard attribute.
• Involve all 27 EU Geological Surveys in the project to make a ‘Ground Stability Layer’ and ‘Summary’.
• Give results to Local Authorities, Geoscience Institutes and the public .
• PROVIDE ACCESS TO GEOHAZARD INFORMATION

Geology
The ‘Ground Stability Layer’ is a vector layer to be made by the Surveys. They will make it by importing into their GIS and interpreting:
Satellite terrain-motion data,
Basic geology (that they hold),
Any other pertinent spatial information, e.g. borehole data that they hold.
From this on-screen analysis, the Surveys will digitise around the main hazard areas, assigning a tag to each, facilitating a hyperlink from the Ground Stability Layer to text within the Geohazard Summary document.

Conclusions
• PanGeo will establish an INSPIRE-compliant, free (for 52 towns), online Geohazard Information Service.
• All EU 27 national Geological Surveys included.
• Aimed at Local Authorities, Geological Surveys and the EU Citizen.
• Question: Should geohazard information be made openly available to the public?
