Geological Hazards
Mt. Dandenong Ranges, Macedon Ranges
Rock and Mud Slides – Steep slopes in these hills are prone to rock and mud slides, especially during heavy rains
Solution – Leave as many trees and vegetation on hill slopes as possible, remove unstable soil
Melbourne Region
Soil and Clay Movement – Melbourne region is prone to soil movement due to shrinkage and expansion of water sensitive clays
Solution – Construct adequate footings and/or slabs to resist soil movement
Coastal Erosion – Bayside coastal areas are currently undergoing erosion due to wave action
Solution – Vegetate coastal areas and replenish shoreline with rock/sand as necessary
Gippsland
Generally same as Melbourne Region
Earthquakes – Earthquakes are common in the Foster/Wilsons Prom and Rosedale Areas as movement occurs along the Foster and Rosedale Fault Systems
Kiewa Valley and Eastern Victoria Mountain Region
Earthquakes – Earthquakes occurring along fault systems i.e. Kiewa Valley Fault System
Rock and Mud Slides
All Victorian Coastal Areas
Coastal Erosion -Coastal areas are currently undergoing erosion due to wave action
Solution – Vegetate coastal areas and replenish shoreline with rock/sand as necessary
Non Geological Hazards
Western Victoria
Drought
Bushfires – in Summer
Electrical Storms – in Summer
Gales – Winter
Dust Storms – Summer
Heat Waves – Summer
Eastern Victoria
Floods – in Winter
Gales – in Winter
Electrical Storms – in Summer
Bushfires – in Summer
Drought – in Summer
Geological Hazards
All Coastal Regions
We are currently undergoing a phase of sea level rise with all coastal areas undergoing erosion. This is likely to get worse in the future.
Gippsland
Further faulting and earthquakes along the Foster and Rosedale Faults
Eastern Victorian Highlands
Further faulting and earthquakes along major faults i.e. Kiewa Valley Fault System
Western Victoria
Possible renewed volcanism near Quaternary Scoria Cones and Flood Basalt Plains
Non Geological Hazards
Climate Warming – Due to increased CO2 Levels in atmosphere producing warming effect
Solution – Reduce CO2 emissions to 0% from fossil fuel burning
UV Radiation – Due to ozone depletion from release of chlorofluorocarbons and other pollutants in atmosphere
Solution – Discontinue use of chlorofluorocarbons and other polluting chemicals
