Table 2 Loss types supported by RiskScape for all perils

From: Evaluating the impacts of volcanic eruptions using RiskScape

Function type

Description

Possible states / values

Possible asset types

Damage state

The extent to which the asset is damaged.

See Table 3

• Buildings

• Electricity cables

• Network junction point

• Pipelines

• Roads

• Telecommunication cables

• Waterways

Exposed state

Whether or not an asset is exposed to the hazard

-1 – Unknown: Outside of the modelled area

0 – Not exposed: Inside the modelled area but hazard indicates zero intensity

1 – Exposed: Inside the modelled area and greater than zero hazard intensity

All

Functional downtime

Productive time lost due to the impact of the hazard on the asset.

Person-days

• Buildings

• Electricity cables

• Network junction point

• Pipelines

• Roads

• Telecommunication cables

• Waterways

Human displacement

A measure of the extent to which humans and human activities are displaced by exposure of the asset to the hazard.

0 – None: No or minimal evacuation necessary (less than 1 day).

1 – One day to 1 week: Evacuation necessary but reoccupation possible after less than a week.

2 – One week to 1 month: Evacuation necessary and reoccupation not possible for between a week and a month.

3 – One month to 6 months: Evacuation necessary and reoccupation not possible for between 1 and 6 months.

4 – Greater than 6 months: Evacuation necessary and reoccupation not possible for more than 6 months.

Buildings (people are assigned to buildings, with day and night-time occupancy rates as one of the building attribute types)

Human losses

A measure of the detrimental effect on humans who are present in or at a asset.

No or light injury: The person is either uninjured or only injured in ways that can be treated without trained medical assistance.

Moderate injury: The person is injured such that they require expert treatment (paraprofessional or doctor), but which are not immediately life threatening if such treatment is not available

Serious injury: The person is injured such that they require a greater degree of medical care and use of medical technology such as x-rays or surgery, but not expected to progress to a life threatening status, full recovery expected with suitable treatment.

Critical injury: The person sustains injuries that pose an immediate life threatening condition if not treated adequately and expeditiously, or long-term disability.

Dead: The person sustains injuries leading to immediate death.

Buildings (people are assigned to buildings, with day and night-time occupancy rates as one of the building attribute types)

Human susceptibility

The susceptibility to injury of a hypothetical human present in or at this asset.

0 – Insignificant: The hazard will not threaten anyone; only those who deliberately put themselves at risk are susceptible to injury.

1 – Low: Only those caught in exceptional circumstances are susceptible to injury.

2 – Medium: Only the most vulnerable are directly susceptible to injury.

3 – High: Those who can move to a protective environment are unlikely to be susceptible to injury but others will be.

4 – Extreme: Even fit able-bodied people are highly likely to be susceptible to injury

Reinstatement cost

Encompasses all direct costs caused by exposure of the asset to the hazard

Asset Repair Cost: Costs incurred in restoring the asset to its pre-event state

Contents Repair Cost: Costs incurred in returning the contents (if any) of the asset to their pre-exposure state

Services Repair Cost: Costs incurred in returning the services (if any) of the asset to their pre-exposure state

Plant Repair Cost: Costs incurred in returning the plant (if any) of the asset to their pre-exposure state

Stock Replacement Cost: Costs incurred in returning the stock (if any) held at the asset to their pre-exposure state

Cleanup Cost: Costs incurred for necessary demolition, and/or removing debris, silt, effluent etc. from an asset

Disruption Cost: Costs incurred due to the disruption of activities usually conducted in the asset

Vehicle Cost: Costs incurred due to the damage of vehicles located at the asset
