             abstract = "Volcanoes exist all over the world, especially in active tectonic 
                         areas. Volcanic eruptions may cause problems for those who live 
                         next to them due to lava flow, pyroclastic flow, ash, gas and 
                         lahar. Therefore this study aims to understand the risks and 
                         hazards associated with volcanic eruptions and its effect in human 
                         population. Color compositions and the Normalized Difference 
                         Vegetation Index (NDVI) were made with Landsat 7 images. NDVI was 
                         used to calculated to the difference between vegetation and 
                         volcanic deposits, using ENVI 5.3 software. Further processing 
                         included segmentation image classification, based on visual 
                         interpretation, using the E-cognition software. The final map of 
                         lava flows and lahar was prepared using Arcgis 10.3. The results 
                         show that all active volcanoes represent risks for those who live 
                         next to them. As a consequence, constant monitoring of these risks 
                         areas is necessary as well as alert local population. The Remote 
                         Sensing techniques used were effective for volcanic monitoring.",
