The LST and NDVI Before and After Earthquake of West Celebes 2021 Using Terra/Aqua MODIS Satellite Image

Abstract Earthquakes are one of the natural disasters that can cause quite a signifi- cant impact on the surrounding environment. This research aims to analyze changes in Land Surface Temperature (LST) and Normalize Difference Vegetation Index (NDVI) before, during, and after the earthquake in West Sulawesi in 2021 using Terra/Aqua MODIS satellite image data. Terra/Aqua MODIS satellite image data is processed through the Google Earth Engine (GEE) online software. The results of the analysis show that the area showed low LST values and high vegetation growth rates before the earthquake. When an earthquake occurs, the LST value increases drastically, and the NDVI value decreases significantly. The condition indicates the changes in environmental conditions and damage to vegetation due to earthquake shocks. After the earthquake, the LST value decreased again, and the NDVI value increased, indicating the area's vegetation recovery.
