Geological Hazards in Tasmania Geological Hazards in Tasmania

Tasmania is situated on a stable continental plate far from the nearest active plate boundaries, so it is a reasonable assumption that the range of geological hazards to be expected is somewhat limited. However those hazards that do exist in Tasmania pose real risks to people, structures, infrastructure and the environment.

Landslides

Large tracts of land throughout Tasmania are subject to slope instability and about 75 houses are known to have been destroyed by landslides, or demolished due to extensive damage, since the...

Karst Subsidence

Karst landscapes are characterised by a high degree of rock solubility in natural waters and are typical of regions underlain by carbonate rocks (limestone and dolomite). Common landforms include...

Earthquakes

Instrumentally recorded seismicity in Tasmania is low, but are large earthquakes credible in the Tasmanian setting? Tasmania is part of the Australian continental plate and since European...

Tsunamis

The risk that tsunami pose to Tasmania is a subject that has had very little research input and no planning response until recently, as a result of the awareness of the devastating consequences...
