On July 13, 2023, a major fire struck the settlement of Grebaštica in the Šibenik-Knin County, causing material damage to nearby houses and cars and significant environmental harm. This study analyzes the Grebaštica area before and after the fire to calculate the extent of the burned area and the intensity of the fire using Sentinel-2 satellite images and QGIS software. Three vegetation indices were used for the fire analysis: the Normalized Difference Vegetation Index (NDVI), the Enhanced Vegetation Index (EVI), and the Normalized Burn Ratio (NBR). Low values of these indices indicate significant damage to vegetation and soil. The analysis revealed that the NBR index is the most effective in detecting fires due to vegetation reflectance in the electromagnetic spectrum's near-infrared and shortwave infrared regions. In contrast, the NDVI index was the least effective in displaying the burned area. A supplementary vegetation indicator called the Delta Normalized Burn Ratio (dNBR or ΔNBR) was calculated to determine the extent of the burned area. The ΔNBR index also denoted varying degrees of damage and fire risk. The burned area of 642 hectares was determined by integrating this index with the administrative boundaries of Grebaštica. This study demonstrates the simplicity of acquiring and utilizing satellite data and its potential impact on future fire management strategies. Moreover, this study demonstrates the extent and hazards that fire imposes on plants, soil, and the well-being of individuals and animals in fire-impacted regions, offering the potential for enhanced and targeted fire management.
