In recent years there is a drastic increase in the events of forest fire in the North-Eastern states of India mainly Mizoram. In spite of this, not much temporal study related to forest fire has been carried out in this part of the country. Forest fire events could be related to Normalized Difference Vegetation Index (NDVI); Normalized Difference Moisture Index (NDMI);Global Vegetation Moisture Index (GVMI); Aerosol Free Vegetation Index (AFRI 1600) and Land Surface Temperature (LST) which could be analyzed using Landsat 8 satellite data at every 16 days. Processing, estimating and analyzing such high temporal resolution satellite data could be easily carried out using Google Earth Engine (GEE) platform. Hence in this study we used GEE platform to carry out the temporal variation study for several indiceson surface reflectance data of Landsat 8 satellite for part of Mizoram region, India. The analysis was carried out from January 2016 to June 2021 on roughly bimonthly basis.
