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?
