| Hazard |
Impact Statement |
| Earthquake |
Collapsing infrastructure causing partial or complete destruction of tank, leading to
reduced storage capacity. |
| Volcano - ashfall |
Ash causing physical and chemical contamination of rainwater, leading to reduced water
quality. |
| Volcano - lava/pyroclastic flow |
Lava flow causing partial or complete destruction of tank, leading to reduced storage
capacity. |
| Liquefaction |
Loss of soil integrity causing partial or complete destruction of tank, leading to
reduced storage capacity. |
| Landslide - slope collapse |
Loss of ground integrity causing partial or complete destruction of tank, leading to
reduced storage capacity. |
| Landslide - debris impact |
Landslide debris causing partial or complete destruction of tank, leading to reduced
storage capacity. |
| Pluvial flooding |
Flooding due to intense rainfall causing partial or complete destruction of tank,
leading to reduced storage capacity. |
| Fluvial flooding |
River flooding causing partial or complete destruction of tank, leading to reduced
storage capacity. |
| Coastal flooding (storm surge) |
Coastal flooding due to off coast storms causing partial or complete destruction of
tank, leading to reduced storage capacity. |
| Cyclonic wind |
Intense winds causing partial or complete destruction of tank, leading to reduced
storage capacity. |
| Tsunami |
Tsunami waves impacting infrastructure causing partial or complete destruction of tank,
leading to reduced storage capacity. |
| Sea level rise |
Sea level rise impacting infrastructure causing partial or complete destruction of tank,
leading to reduced storage capacity. |
| Heatwave |
Increased demand of water due to high temperatures, leading to reduce supply capability.
|
| Drought |
Reduced rainfall in catchment due to drought, leading to reduced supply capability. |
