Wayanad tragedy: How Kerala can improve its early warning systems for landslides

Hindustan Times  

Chennai: A series of landslides triggered by heavy rains in Kerala’s Wayanad district earlier this week resulted in over 250 deaths while many are still missing. Indian army soldiers engaged in rescue operations at landslide affected village in Wayanad Even though some pilots on landslide warning systems are being done in Himachal and Kerala, experts said a better landslide warning system can be developed by improved integration of historic rainfall data, real-time satellite imagery, and hill slope studies with mechanisms for better public dissemination of warnings. According to Dr. K V Uday, associate professor at IIT-Mandi, who is conducting a pilot on landslide prediction in Himachal, said, “The movement of the slope and parameters like rainfall data or satellite images are key indicators for predicting landslides.” Supported by the NDMA and Himachal Pradesh’s State Disaster Management Authority, Dr Uday’s team has deployed 60 landslide monitoring and early warning systems across Himachal Pradesh. Professor Deepankar Choudhury of IIT-Bombay, who has worked on landslide monitoring systems in Kerala and is chairman of the technical committee on disaster resilience and capacity building under the State Disaster Management Authority, Maharashtra government, said the satellite data is an accurate way of predicting landslides as the sensors on slopes could collapse during landslides. “A model can be created by analyzing historical rainfall data from Wayanad during periods of frequent landslides,” he said.
