Extreme rainfall during 15–17 of June 2013 triggered numerous landslides and caused widespread damage and loss of life in the Bhagirathi and Alaknanda river valleys, with Kedarnath town bearing the brunt of the disaster. In this paper, we present a corroboration of observations gathered from very high resolution satellite data which indicated that two events in close succession caused damage to the Kedarnath town. While the flooding on June 16, 2013 was due to the reactivation of an old landslide that resulted in breaching of the river training wall, breaching of the moraine dammed Chorabari lake on June 17, 2013 caused further flooding and damage to the Kedarnath town. We also prepared a detailed landslide inventory using multi-temporal Resourcesat-2 images (5.8 m) acquired before and after the event in order to avoid issues related to cloud and shadow. A total of 6,013 landslides were mapped, out of which 3,472 landslides with 30.4 km2 area were classified as new ones, 1,137 landslides with 9.1 km2 area were classified as old ones and 1,401 landslides with 11.7 km2 area were classified as reactivated ones. The frequency-area statistics of the mapped landslides shows near completeness of this event-based landslide inventory. The debris brought down by rivers from these landslides, particularly from the glaciated deposits in upstream areas, caused severe river bank erosion in downstream areas.
