One of the most important roles of STH over the years is to document landslide occurrences in our region so that this information though not technical in nature is available to scholars, government departments and others.
Unfortunately, due to the lockdowns and restrictions imposed during COVID peaks we could not carry out these surveys in landslide affected areas very far from Kalimpong however, our Whats App group 'Hazard Alerts' proved extremely useful as a crowd sourced information hub where people reported landslides and heavy rain as they occurred and we were able to record these events in our database.

31Jul2021: Survey of landslide affected areas in Kalimpong after extreme rainfall of 29Jul
We had some of the heaviest rainfall of the monsoons in July 2021 and that resulted in a large number of landslides in Kalimpong on 30Jul2021. We surveyed the affected areas.
This 👆 is undoubtedly one of the largest landslide in the entire Darjeeling - Kalimpong district.
