Debris Flow  occurred at Ambatharu colony on 15th August 2018. The geoscientific cause for the shallow rotational  failure is excess pore water pressure causing  reduction of strength on super saturation. Debris flow happened twice in the same location,
Initiated as a plannar failure debris slide graded as debris flow. Failure observed in weathered seam.
Ambataru colony
Natural drainage to be maintained and relocate house of Annakutty which is on the path of slide.
Unscientific slope modification and excess pore water pressure
