On 15th August 2018 a debris flow occurred along a first order stream near Madakkathara village. The geoscientific cause for the slide is increased pore water pressure and decreased shear strength of slope material, heavy surface run off and widening of
Unstable debris material present at source of the slide
Pullankandu slide
Madakkathara  village
Removal of unstable debris material from the stream channel and from slide source, provision of catch fences to arrest the rolled boulders
Increased pore water pressure and decreased shear strength of slope material, heavy surface run off and widening of stream channel weakening along joints.
