Risk ​Ass​essment Report​​​


​This district risk assessment report summarises the results of the State Risk Project risk assessment workshops in the Pilbara Emergency Management (EM) district. It co​​vers five priority hazards, as identified by the Pilbara District Emergency Management Committee (DEMC). The workshop series was conducted between July and September 2016.

District Risk Profile


​​​​
​​​​​​​​Re​​​port highlights​​​​:

  • T​he re​​sults for the five hazards assessed reveal that:

​​- 1% of the risks were assessed as extreme​;

​​- 10% of the risks were assessed as high​​;​

- 2% of t​he risks could cause catastrophic consequences​.​​​


  • ​​The flood scenario (severe flooding across the Pilbar​a as a result of a slow movi​ng Category 5 cyclone) produced the greatest number of high and medium risks combined, likely due to its widespread nature. This scenario would have the greatest impact on the social fabric of the district. ​


  • As a result of the human epidemic and air crash scena​rios, the health system would be stretched and emergency services would be overwhelmed, particularly the Royal Flying Doctors ​Service (RFDS) in transporting burns and critical patients to Perth for treatment.


  • ​T​he greatest economic losses to the Pilbara would likely stem from impacts to the marine and mining industries. The marine tra​nsport emergency scenario would have a significant impact on mining exports from the region, as the channel could potentially be blocked for up to 10 days resulting​ in losses of greater than $227 million. The cyclone scenario could also result in significant financial losses. These losses would likely be from both the impact of severe winds causing the Port and mining industry to come to a temporary halt and from the resultant severe flooding across the Pilbara causing damage to mine sites and rail infrastructure that service the mine sites. 


  • Th​e cyclone scenario could result in the evacuation of over 5000 people, particularly as a result of an expected 12 metre storm surge in Karratha town. The need to house this large nu​​​​​​​mber of people could be an issue, with a strain on public facilities.
