A massive landslide last week crushed a settlement of 83 tea estate workers in Munnar in Idukki, Kerala. The landslide happened on August 6 at Pettimudi, a hamlet in Rajamala ward under Munnar village panchayat in Kerala’s Idukki district.
About:
Rajamala includes Eravikulam National Park, and the landslide was triggered from a shola forest region in the national park. Rocks, slurry and sludge crashed down a distance of around 1½ km to a patch of valley in Pettimudi, crushing the houses of estate workers.
The location where the landslide was triggered has a 40° slope, and any slope above 20° is vulnerable to slipping during heavy rain. The soil has a high content of sand, which absorbs more water, takes a loose form, and is at risk of slipping down.
