Rainfall Analyses of Coonoor Hill Station of Nilgiris District for Landslide Studies The study analyzes rainfall patterns at Coonoor Hill Station in the Nilgiris District to assess their impact on landslide occurrences over 80 years (1935-2013). Findings indicate an increase in annual rainfall, averaging 1773 mm in recent decades, with significant variability during pre-monsoon and monsoon periods. Extreme rainfall events, particularly during the North-East monsoon, are linked to landslides, with 200 mm or more triggering substantial landslide activity. The research underscores the need for effective monitoring and preventive measures in the region, highlighting the dynamic nature of rainfall thresholds for landslide susceptibility influenced by local terrain conditions.
