The combined earthquake hazard map is a generalised map of earthquake hazard refl ecting possible effects on a typical range of facilities (buildings, roads, services, etc). On rare occasions, a fire which starts following an earthquake can develop into a serious emergency. Calculations between each of these fields were carried out on a record by record (or grid centroid) basis.The calculations then followed for each hazard:• calculate the damage for each item of infrastructure for each hazard, based on the damage ratios given in Tables 6 through 10.• modify the liquefaction damage based on an assessed likelihood that liquefaction will occur in the area• total the damage for each hazard• add the damage for each hazard at each cell centroid to get the total damage due to combinations of hazard, a combined hazard index (CHI).These CHI values were then grouped into the severity using the CHI_HAZ_GR field, which was symbolised as the SEVERITY field.
