Hazard Module

Loss model component containing information about hazard events or scenarios.

Hazard Layers

Hazard layers are a physical representation of a hazard event or scenario. Hazards are spatially represented as vector or raster data, displaying the area extent exposed to hazardous processes and/or the intensity of hazardous processes.


Example of flood hazard exposure represented as vector polygon features.

Asset Module

Loss model component containing information about assets and asset attributes.

Asset Layers

Asset layers are a representation of people or made-made or natural resources (i.e. assets) that have a tangible or intangible value. Assets are spatially represented as vector data, displaying their location and attributes that are vulnerable to direct or indirect loss from natural hazards.


Example of building vector point feature locations and construction types.
Example of road vector polyline feature locations.

Vulnerability Module

Loss model component containing information about asset vulnerability to direct or indirect loss from natural hazards.

Vulnerability Models

A vulnerability model is a representation of asset vulnerability to direct or indirect loss from a natural hazard. These models, often refer to as vulnerability (damage or damage-to-loss) or fragility functions, comprise a single or series of statistical functions and/or rules (algorithm) that relate the intensity of hazardous processes to either a damage ratio (i.e. 'cost to repair'/'cost to replace') or state (i.e. conditional probability (P) that a damage state will be reached or exceeded). These values are applied direct or indirect loss estimations for asset exposed to a natural hazard.

RiskScape software users are currently unable to install vulnerability models in the RiskScape system without assistance from RiskScape developers. Development of this functionality will commence following RiskScape 1.0 release.


Please submit any enquiries on vulnerability models for the RiskScape system to the helpdesk.


Loss Module

Loss model component containing information about losses sustained by assets exposed to a natural hazard event or scenario.

Loss Layer

Loss layers are a representation of asset exposure or direct or indirect loss from natural hazards. Losses are spatially represented as vector data, displaying exposure or loss information for individual or aggregated (i.e. aggregation layer) asset features.


Example of individual buildings identified as exposed to flood hazards.
Example of direct damage loss (repair cost) estimates for individual buildings exposed to flood hazards.
Example of direct damage loss (repair cost) estimates aggregated for individual buildings exposed to flood hazards.

Aggregation Layer

Aggregation layers are geographic areas representing loss information aggregated asset features. These areas are spatially represented as vector data, usually polygon features.

Example of census meshblock boundaries.
Example of land parcel boundaries.
