The Fault Awareness Overlay indicates areas where deformation of the ground may occur due to fault rupture, however in these areas the fault is poorly defined and there is significant uncertainty regarding the specific fault location. This uncertainty is often due to the fault being buried beneath overlying soil, thick alluvium, or landslides, where no surface expression of the fault is observable on the ground surface, or where small-scale geological maps are the only available evidence of the fault’s location. Fault rupture and deformation of land in the Fault Awareness Overlay can also cause significant damage to buildings and infrastructure, and harm to people.
