Geologist explains the factors behind the devastating landslide in Wayanad, Kerala

 

• Geologist Dr. K Soman attributes the massive landslide in Vellarimala, Wayanad, to fractured rocks and excessive rainfall.

• The landslide originated from a saddle formed by fracturing, causing water to accumulate in the faults and leading to a forceful release of soil, rocks, and vegetation.

• The significant difference in altitude between Vellarimala and the affected towns intensified the impact of the debris flow.

• Unlike the landslide in Shirur, Karnataka, which was solely caused by unscientific highway construction, the Wayanad tragedy is linked to improper land use patterns.

• Tea plantations and the diversion of a river's course contributed to the vulnerability of Mundakkai and Chooralmala, areas that had experienced previous landslides.
