<div style="font-family:'Segoe UI';font-size:14px;font-style:normal;font-weight:400;line-height:20px;">This dataset represents the municipal‑level distribution of earthquake hazard across the study area. The dataset was generated by converting seismic event information from the Council for Geoscience into a continuous hazard raster surface, classifying the data into five hazard classes using natural breaks, and summarising the maximum hazard value within each municipal boundary. The resulting feature class enables planners, disaster management practitioners, and risk analysts to identify municipalities with elevated seismic hazard levels and incorporate these insights into multi‑hazard assessments and mitigation planning.</div> |
