The Idukki, Rajamala landslide amid the spike in the number of coronavirus cases and rainfall was altogether a bad news for Kerala. The unfortunate event took place on August 6, 10:45 pm, in a small village of Pettimudi, in the Rajamala ward in Munnar of Idukki district.
Rajamala includes Eravikulam National Park, and a shola forest region triggered the landslide 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 single-room houses of estate workers that stood in two rows, face to face.
Given below is a video retweet by PIB Kerala, showing the rescue operation in the Rajamal area in the Idukki district.

According to officials, Pettimudi, occupied by 83 estate workers of the Kanan Devan Hills Plantation Company Private Limited, who lived in 30 single-roomed houses provided by the estate, were destroyed, thus rendering them helpless and homeless.
Last week, the district Information Office said two National Disaster Response Force (NDRF), police officers, a full unit of Idukki fire and rescue team, a team each from Kottayam, Thiruvananthapuram, along with a team which received special training are leading the rescue operations in Idukki’s Rajamala.
As per the latest reports on Sunday, the death count rose to 58, with only a handful of rescued victims. According to the district information office, the search operation is underway to find the remaining 12 persons who went missing after the landslide. Very few residents, who were away at the time, managed to escape. The officials have told that 57 other families will be relocated to a much safer area.
How did it happen?
According to the Kerala Geology Department, the geographical point which initiated the landslide has a 40° slope. Any slope which is above 20° is prone to slipping during a heavy rainfall;
- As per the analysis, conducted by the State Disaster Management Authority, on landslides, heavy rainfall soaks the soil on the slopes. The land with ‘higher clay content’ is capable of retaining water but not draining the excess water, eventually leading to high water pressure in the slopes;
- Heavy loading in the hills caused by buildings on the ‘cut and fill’ ground, without any necessary protective measures, makes the location prone to landslides.
- Another notable factor is that the frequent landslides, caused the course of rivers to changed, and river channels have been blocked.
As per a news report by The Indian Express: “a cloudburst on the night of August 6 could have set off the deadly landslide in Pettimudi, Idukki which claimed nearly 70 lives of tea plantation workers and their families, said a top official.” The report further quoted that rainfall statistics put out by Pradeep John, a famous weather blogger from Tamil Nadu, the Pettimudi station, received 1842.7 mm (184 cms) rainfall from August 2-7, the highest rainfall in that period in Idukki district.
Cloudburst is a natural phenomenon wherein an extreme rainfall in a short period to a small geographical area.
