Wayanad and Western Ghats Landslide Risk: Amrita University Sensor-Based EWS and IIT Mandi Probabilistic Models Being Validated

Following recurrent landslide disasters in Wayanad and Western Ghats, two promising Early Warning System (EWS) models are being validated — Amrita University's sensor-based system (using tilt meters, pressure gauges, accelerometers) and IIT Mandi's probabilistic forecasting model. These are being evaluated for deployment under the National Disaster Management Authority (NDMA). India has 13% of its landmass (0.42 million sq km) classified as landslide-prone, with the Western Ghats, Himalayas, and Northeast India being the most vulnerable zones.
