Landslide wreaked havoc in a tea plantation workers' neighbourhood in Rajamalai in Idukki district on August 6.
Only 12 people survived the landslide that flattened a row of 20 one-room quarters where around 80 people lived.
The Pettimudi disaster had claimed the lives of 19 children.
Heavy rain and cold weather with low visibility made the rescue operation difficult for the NDRF personnel at Pettimudi.
Landslides killed 59 people in Kavalappara in Malappuram and 17 died at Puthumala in Wayanad.
