Kodagu is a hilly terrain in the southwestern part of Karnataka state which is showing a tremendous growth in the tourist industry. Landslides in Kodagu are believed to be small incidences of rainy season and never received much attention from the researchers or media as it never caused constraints either on general public or government machineries. During the months of June and July, 2018, Kodagu district received 5894 mm rainfall, a 22.45% departure from normal rainfall. Added to this, in the first three weeks of August, 2018, the district received a total rainfall of 1,675 mm and in a single day on August, 17 the district received 300 mm rainfall causing landslides in more than 80 locations resulting in the death of 20 persons, rendering about 2200 homeless and the government estimated a total loss of about Rs. 1400 crore. The present work analyses the causes which is essential for prevention of damages in future and promotion of mitigation measures. Jodpal, Monnamgeri, Madikeri town and Makkandur in Mercara taluk and Iggodlu in Somawarpet taluk are the worst affected areas in the forms of economic loss and fatalities. Preliminary studies carried out by the present investigators revealed that the intense weathering and well developed joints in rocks have rendered them less cohesive and heavy rainfall acted as the triggering factor for the rock fall, debris slide and flow. Human interventions in the form of modification of slope and obstruction to the natural drainage are the other factors to trigger the landslides. Salient features on landslide preventive measures in Kodagu district is also outlined at the end.
