Service Description:

Geologic processes capable of causing damage, or loss of property and life, are called geological hazards or geohazards.

PanGeo focused on geohazards relating to ground instability in urban areas where the impact can cause the most damage.

Ground movements (upwards, sideways or downwards) can be caused by a wide range of natural and manmade geological processes. Some processes are so slow they are barely visible to the naked eye whilst others may cause large scale obvious movement in the ground. Both have the potential to severely damage urban infrastructure and buildings.

It should be noted, however, that many buildings, especially modern ones, are built to such a standard that they can remain unaffected in areas of significant ground movement.

Ground instability can be caused by a range of naturally occurring reasons such as changes in geology, groundwater or dissolution features in chalk and limestone. Man-made causes include mine working, basements, poorly compacted ground or weak structures.

The effects of natural ground instability often occur over a local area whereas the effects of natural ground movements occur over larger areas.

The data was created by analysing GSI datasets such as bedrock, quaternary sediments (glacial), karst (landscape where the bedrock has dissolved eg limestone), landslides and geotechnical (boreholes and site investigations). Also, historical maps and aerial photos from Ordnance Survey Ireland (Tailte Eireann). European Space Agency persistent scatterer interferometry (PSI) which uses images taken from space to see where the Earths surface has moved was also used. Finally, on site checks were carried out by geologists.

This data shows areas of Dublin where the ground has been observed or has the potential to be unstable.

This map is to the scale 1:50,000. This means it should be viewed at that scale. When printed at that scale 1cm on the map relates to a distance of 500m.

It is a vector dataset. Vector data portray the world using points, lines, and polygons (areas).

The data is shown as polygons. Each polygon holds information on the hazard type, hazard, category, method determined, confidence, area (km2), observation start and end dates, classification and its unique identifier.

PanGeo was a 3-year Collaborative Project of the European Commission that started on the 1st February 2011.
