COMBUS's multi-peril models are designed to address the needs of (re)insurers for the major Australian events. The models analyse the magnitude of large events and frequency of smaller events, as well as correlations between the different perils due to regional weather patterns.
|Australia Bushfire: The bushfire peril model covers fires in grassland, scrub or forest that cover wide areas and cause damage and loss to the environment and property. The event occurrence model is based on parameters such as temperature, humidity and wind speed and the probability of building loss takes into account type of vegetation as well as physical distance.||Australia||Bushfire||Available|
|Australia Low Pressure System: The low pressure system model covers five different categories of Australian weather which have similar event features and mixes of damage and loss from sub-perils. The five weather types are East Coast Lows, Eastern Low Pressure Troughs, West Coast Troughs, Southern Ocean Lows and Monsoonal Low Pressure Troughs.||Australia||Low pressure system||Available|
|Australia Severe Convective Storm: The severe convective storm model covers thunderstorm events due to instability in different layers of the atmosphere which can include the loss-causing sub-perils of strong winds, flooding, hail, tornadoes and lightning. These events tend to last for a number of hours with the most damage occurring over a short period of time, compared to other weather events which may last for more than one day.||Australia||Storm||Available|
|Australia Earthquake: The earthquake model includes events with epicentres in Australia and in surrounding regions that lead to significant ground motion for Australian exposures. Site intensities in each modelled event are estimated based on a blend of published attenuation studies while damage to property takes account of Australian design codes.||Australia||Earthquake||Available|
|Australia Cyclone: The full tracks of each cyclone are modelled, including events crossing the coastline and those bypassing coastal regions. For each event in the database the maximum wind speed is determined for each location of interest and using that wind speed, modified by adjustments for terrain and topography, loss to individual buildings and contents is estimated. Wind, flood and storm surge.||Australia||Cyclone||Available|
