<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>

The purpose of this dataset is to provide a spatially standardised, municipality‑level representation of earthquake hazard intensity. It supports seismic risk profiling, informs disaster management planning, and assists authorities in prioritising areas where earthquake‑related preparedness, awareness, and mitigation strategies may be required.

Represents the maximum earthquake hazard class (1–5) occurring within each municipal boundary. Values are derived from the Earthquake_Hazards raster using Zonal Statistics (Maximum), where the raster contains earthquake hazard classes based on the reclassification of seismic magnitude data from the Council for Geoscience.

The Hazard field stores the final earthquake hazard classification assigned to each municipality. This value is derived from the Magnitude field (maximum earthquake hazard class extracted from the Earthquake_Hazards raster) and converted into a simplified hazard category for reporting and comparative analysis. The field was populated in ArcGIS using Calculate Field operations following attribute selections.
