Section 4.3
Scenario 1: Tropical Cyclone (Category 3 - 5)
The QERMF Severe Tropical Cyclone risk assessment scenario included destructive winds, heavy rainfall
(>500 mm in 24 hours) leading to flash and moderate to major flooding and landslides. The risk assessment
included assessment of storm tide, flooding, coastal erosion, and landslide associated with the cyclone.
The determined QERMF likelihood for Scenario 1 can be found in Table 3 above.
A summary of the residual risk level for Scenario 1 can be found in Table 4 below.
Geographic vulnerability to the effects of scenario 1 modelling is illustrated in Figure 9 below.
