“…Field observations showed that landslide areas correlated positively with the agricultural lands on moderate-to-high slope category (Rautela and Paul 2007). Kaliganga, Madhyamaheshwar and Kali valley of the central Himalayan Region of Uttarakhand suffered heavy landslides in August 1998 causing the death toll to cross the 300 mark.…”

Deluge of June 2013 is the worst disaster faced by the nation in recent times. Changing rainfall pattern in the previous some years has made heavy localized precipitation all the more common in Uttarakhand and the same is a cause of concern for the state government, meteorologists and other researchers. These incidences cause enormous loss of human lives, property, infrastructures and natural resources. Moreover rainfall in the study area is highly variable even over short distances. Dissected topography and tectonically active nature of the area further promote mass movement and slope instability. Increased indiscriminate anthropogenic intervention along the river banks, on glacial sediments, thick colluviums zones and river borne materials on moderate to steep slope, has often resulted in devastation in the area. The study highlights causes of slope instability together with the geomorphic changes and suggestions for future developmental initiatives within the district.

“…Landslides triggered by rainfall have been discussed previously by various researchers (Anbalagan, 1996;Takahashi et al, 2001;Dai et al, 2003;Dortch et al, 2008;Tsai and Chen, 2010;Tsai and Wang, 2011;Gupta and Uniyal, 2011;Lepore et al, 2012;Bhan et al, 2015). A few recent examples from the Indian Himalayan region (Rautela and Paul, 2001;Kumar et al, 2003;Mandal and Maiti, 2013;Asthana and Sah, 2007;Sati et al, 2011;Rana et al, 2012;Rautela, 2012;Martha et al, 2015) demonstrate the complex cascading processes that directly threaten the population, including human activities and infrastructure, communication network, and agricultural lands. These landslides and associated mass movements adversely affect the regional socioeconomic setup.…”

Assessment of landslide hazards induced by extreme rainfall event in Jammu and Kashmir Himalaya, northwest India

et al. 2017

In the Indian Himalayan region (IHR), landslide-driven hazards have intensified over the past several decades primarily caused by the occurrence of heavy and extreme rainfall. However, little attention has been given to determining the cause of events triggered during pre-and post-Indian Summer Monsoon (ISM) seasons. In the present research, detailed geological, meteorological, and remote sensing investigations have been carried out on an extreme rainfall landslide event that occurred in Sadal village, Udhampur district, Jammu and Kashmir Himalaya, during September 2014. Toward the receding phase of the ISM (i.e., in the month of September 2014), an unusual rainfall event of ~488.2 mm rainfall in 24 h took place in Jammu and Kashmir Himalaya in contrast to the normal rainfall occurrence. Geological investigations suggest that a planar weakness in the affected region is caused by bedding planes that consist of an alternate sequence of hard, compact sandstone and weak claystone. During this extreme rainfall event, the Sadal village was completely buried under the rock slides, as failure occurred along the planar weakness that dips toward the valley slope. Rainfall data analysis from the Tropical Rainfall Measuring Mission (TRMM) for the preceding years homogeneous time series (July-September) indicates that the years 2005, 2009, 2011, 2012, and 2014 (i.e., closely spaced and clustering heavy rainfall events) received heavy rainfalls during the withdrawal of the ISM; whereas the heaviest rainfall was received in the years 2003 and 2013 at the onset of the ISM in the study region. This suggests that no characteristic cyclicity exists for extreme rainfall events. However, we observe that either toward the onset of the ISM or its retreat, the extreme rainfall facilitates landslides, rockfall, and slope failures in northwestern Himalaya. The spatiotemporal distribution of landslides caused by extreme rainfall events suggests its confinement toward the windward side of the Himalayan front.
