Geosciences Applications

The Geohazard studies are primarily focussed on landslides, earthquakes and volcanoes. High resolution satellite data are used for post disaster damage assessment and landslide inventory preparation in the case of landslide or earthquake. Major landslide events studied recently include Kerala-Karnataka-Tamil Nadu (2018), Mizoram-Tripura (2017) and Sikkim (2016). Landslide Hazard Zonation maps are made on 1:25,000 scale along major tourist and pilgrimage routes in the states of Himachal Pradesh and Uttarakhand. These maps is integrated with the rainfall forecast data to develop and issue landslide early warning through Bhuvan portal. In recent years several earthquakes struck India namely the Kashmir earthquake (2005), Sikkim earthquake (2011) and Nepal earthquake (2015). Post-disaster very high resolution (VHR) satellite data have been used to provide detailed information on damage and geological changes for a large area in a short time. In addition to these, the recent eruptions of the Barren Island volcano have also been monitored using temporal satellite data.
