The Cost of Post-Earthquake Fire in Wellington
Authors: Lloydd, Delwyn ; Thomas, Dr. Geoff
A geographical information system (GIS) model containing data on buildings stock is used to
determine loss of property in Wellington City due to fire following the maximum credible earthquake
on the Wellington Fault. The model uses fire spread ‘rules’ to calculate fire spread by radiation,
sparking and branding. The ‘rules’ were based on historical data and radiation calculations. Initial
results give a range of probable loss from NZ$50 M to NZ$ 270 M depending on wind speed, and the
locations of ignitions.
