The landslide events, that occurred in August 2018 in the Idukki district Kerala, India were surveyed during 12–14 September 2018. Many landslides were studied through field observations to decipher their mechanism and mitigation measures have been recommended. Possible causative factors responsible for these slope failures have been discussed. This event was the most devastating disaster that affected millions of people and the second such event after the Kedarnath tragedy (2013) during this decade. The primary causes responsible for initiation of these landslides were unexpected intense rainfall, unplanned development and urbanization. This study on field observationbased interpretations will help academicians, researchers and field engineers to plan future initiatives for reconstruction planning and implementation in line with future disaster risk reduction.Keywords

The Birik Dara landslide occurred at around 10 pm local time (GMT+5:30) on 20 October 2021 on National Highway-10 in the Kalimpong region of Darjeeling Himalaya, India, and disrupted traffic for more than a week. This study presents an overview of the landslide and reveals the present stability status of the slope. The slope stability assessment was carried out using data collected from the field during a site visit in the second week of November 2021. The findings of this study indicate that the landslide occurred on a critically unstable slope and it may be triggered again in the near future with more damage. Therefore, immediate attention is required regarding slope stabilization measures to avoid future threatsFull Text
