PanGeo explained - What has been mapped?
Geohazards in each participating town have been mapped by the corresponding National Geological Survey using a rigorous methodology defined by PanGeo. In this way, detailed local knowledge of geohazards has been combined with satellite observations of ground movement to create a comprehensive map of all geohazards present in each town, ensuring that different towns can be compared. The map of geohazards for each town is called the ‘ground stability layer’.
Potential and Observed Geohazards
Geohazards can be categorised as either ‘potential’ of ‘observed’. A potential geohazard exists where the local geology makes it more probable for ground movement to occur even if movement has not been measured. Observed geohazards are where ground movement has been measured (by whatever method). The PanGeo ground stability layers captures both potential and observed geohazards.
