This district risk assessment report summarises the results of the State Risk Project risk assessment workshops in the Metropolitan Emergency Management (EM) districts. It covers seven priority hazards, as identified by the Metropolitan District Emergency Management Committees (DEMCs). The workshop series was conducted between June and September 2016.
For the purpose of the risk assessment, the four Metropolitan District Emergency Management Committees were assessed as one geographical district.
The results for the six hazards assessed reveal that:
- No extreme risks;- 9% of the risks were assessed as high;- < 4% of the risks could cause catastrophic consequences.
- No extreme risks;
- 9% of the risks were assessed as high;
- < 4% of the risks could cause catastrophic consequences.
Earthquake has the greatest proportion of high risks (23%) and was the only hazard to produce catastrophic consequences. Risks centred upon the impacts to private and commercial buildings, business activities, environmental contamination from toxic substances, transport routes, recovery activities, and the service delivery of CPFS, WA Health and ambulance services. Damage to buildings from the earthquake was anticipated to be significant, with estimates of 30% of the metropolitan building stock sustaining moderate to complete damage. The cyclone and flood impacts on commercial and private buildings are likely to be greater than the 2010 Perth Storm event, which caused more than $1 billion worth of damage. The cyclone scenario posed a high risk to the aviation sector with estimated economic losses of more than $759 million due to the cost of the aircraft repairs and replacements and the inability to maintain passenger demand in the short term. The earthquake and HAZMAT (Chemical substance) scenarios would be expected to result in the greatest number of deaths and injuries, but all hazards were anticipated to cause at least three deaths.The bushfire, cyclone, flood and HAZMAT (Chemical substance) scenarios could generate a decline in economic activity and/or loss of asset value greater than $759 million. The earthquake scenario produced high economic risk statements equating to greater than $7.59 billion of losses.
