From Winter 1973 to Global Disasters: the Dual Timeline of 'Landslide' Explained
By James H. Sterling
The recurring disaster in Kerala's Wayanad district shows what happens when extreme tropical weather strikes an ecologically fragile hill zone. The Western Ghats ecology is an ancient, weathered chain of mountains characterized by steep gradients, lateritic soils, and high seasonal precipitation. In early July 2026, Kalladi near Meppady witnessed another devastating slide barely two years after the deadly 2024 Chooralmala and Mundakkai debris flows leveled entire townships.
State officials and environmental researchers increasingly label these disasters man-made. The fundamental issue is unregulated slope engineering. Over the past three decades, monoculture tea and coffee plantations, highway widening cuts, and unmonitored tourism resorts have systematically replaced deep-rooted endemic rainforest trees with shallow-rooted crops. Hill district deforestation strips the organic root network that mechanically anchors soil mantles to underlying charnockite bedrock.
When the southwest monsoon dumps hundreds of millimeters of precipitation in a 24-hour window, the saturated hillside finds nothing to brace it. Excavations for basements and hillside roadcuts leave sheer vertical banks with zero retaining reinforcement, turning regular monsoon downpours into fatal disasters.
