“…12 millions of cubic meters of material developed on a valley slope of ~70 (I. Penna et al, 2021), similar to what has also been documented in the Higher Himalaya from other parts of the north-western Himalaya (Jamir et al, 2020;Kumar et al, 2019).…”

“…Numerous studies indicate that various geomorphic indices are good proxies to determine the inherent tectonic activity in the region, which in turn affect the distribution of erosion potential and the development of landslides (Bull, 2009;Jamir et al, 2020;Kumar et al, 2019). In situ topographic stresses, resulting from interaction between tectonic stress and topography, also have considerable influence on rock deformation and play a vital role in weakening the rock mass and inducing landslides (G. K. Li & Moon, 2021;Panthi & Nilsen, 2006).…”

“…Zone III, located in the Lesser Himalaya, is characterized by the lowest steepness index, lower stream length gradient index, and the highest valley floor width to valley height ratio, and thus exhibits the lowest tectonic activity (Bull, 2009;Jamir et al, 2020;Kumar et al, 2019) as compared to the tectonic activity in Zones I and II. This is also evidenced by the gentle channel gradient of Teesta River, gentler valley slopes, and wider valleys (Figure 5a,b) in this part of the area.…”

Landslides are a common and widespread phenomena in tectonically active mountains, impacting on landscape development, and lanslides pose a serious threat to the lives and properties when these interfere with humans and their associated infrastructure. However, the spatial distribution of these landslides is controlled by various geological and geomorphological parameters, including the neotectonic activity and the climatic pattern of the area. In the present study, various geomorphic parameters such as longitudinal and topographic swath profile, valley floor width to valley height ratio, channel steepness index, and stream length gradient index, along with the rainfall pattern of the Teesta river valley, Sikkim Himalaya, were correlated with the spatial distribution of landslides in the area. It has been concluded that landslides in the Higher Himalaya, north of the Main Central Thrust behind the orographic barrier, owe their origin mainly to the higher tectonic activity, and adjacent to the Main Central Thrust in the front of the orographic barrier to both tectonic activity and the higher rainfall. The distribution of landslides in the Lesser Himalaya is dominantly controlled by lithology and is mainly triggered by the rainfall.

“…Some of the chronic landslides in the area are the Wariya landslide (Yamuna valley), Varunavat Parvat landslide and Natela landslide (Bhagirathi valley), Kaliayasaur landslide (Alaknanda valley), Byung Gad landslide (Mandakini valley), Malpa landslide and Khotila landslide (Kali valley), Surabhi Resort landslides (Mussoorie township), Balia Nala landslide and Sher ka Danda landslide (Nainital township), and there are many more including the Totaghati landslide. All these landslides have been studied in isolation by various workers to understand their causes and consequences in the region and on the environment (Sati et al 1998;Gupta and Bist 2004;Chaudhary et al 2010;Onagh et al 2012;Gupta et al 2016Gupta et al , 2017Jamir et al 2018Jamir et al , 2020Kundu and Patel 2019;Solanki et al 2019;Ram et al 2020).…”

Landslide and related mass movement activities are common and one of the most destructive natural hazards in the mountainous terrain including the Himalayas. Of the 11 administrative states in the Indian Himalayan region, the state of Uttarakhand has witnessed enhanced activities of these phenomena. It is therefore essential to understand the regional scale landslide susceptibility assessment of the state and in the present study, landslide susceptibility mapping for the entire state has been carried out using bivariate weight of evidence and information value methods which depict that around 51% of the area is located in the high and very high landslide susceptible zones, 22-23% in the moderate and *26-27% in the low and very low landslide susceptible zones, and slopes ranging between 40°and 60°, located at an elevation of 2000-4000 m, facing towards southern sides and covered with limestone, gneiss, quartzite and phyllite, have higher propensity towards development of landslides in the region.

Abstract. Prediction of potential landslide damming has been a difficult process owing to the uncertainties related to landslide volume, resultant dam volume, entrainment, valley configuration, river discharge, material composition, friction, and turbulence associated with material. In this study, instability patterns of landslides, geomorphic indices, post-failure run-out predictions, and spatio-temporal patterns of rainfall and earthquakes are explored to predict the potential landslide damming sites. The Satluj valley, NW Himalaya, is chosen as a case study area. The study area has witnessed landslide damming in the past and incurred losses of USD ∼30 million and 350 lives in the last 4 decades due to such processes. A total of 44 active landslides that cover a total ∼4.81±0.05×106 m2 area and ∼34.1±9.2×106 m3 volume are evaluated to identify those landslides that may result in potential landslide damming. Out of these 44, a total of 5 landslides covering a total volume of ∼26.3±6.7×106 m3 are noted to form the potential landslide dams. Spatio-temporal variations in the pattern of rainfall in recent years enhanced the possibility of landslide triggering and hence of potential damming. These five landslides also revealed 24.8±2.7 to 39.8±4.0 m high debris flows in the run-out predictions.
