Wayanad Tunnel Tragedy: Mountainside Collapses Again

A recent mountainside collapse has occurred at the site of the Wayanad Twin Tunnel project, a significant infrastructure undertaking in Kerala's Vellarimala ranges. Six workers are confirmed dead, with many others missing following the incident. The tunnel project is designed to bypass the accident-prone Thamarassery Ghat road, improving connectivity between Kozhikode and Wayanad districts.

Concerns were raised during the project's environmental clearance regarding its alignment through highly landslide-prone terrain. The clearance document acknowledged the area's history of devastating landslides, including a recent one in 2024 and another in 2019. It also noted the project's proximity to the Nilgiri Biosphere Reserve and its passage through ecologically sensitive villages.

Despite warnings about geological uncertainty and potential risks like blasting vibrations and altered drainage, the project received environmental clearance with numerous conditions. This clearance was later challenged but upheld by the courts, which deemed the tunnel a project of national importance. The incident echoes other tunnel collapses across India's mountains, where engineering models have struggled to anticipate geological realities exacerbated by climate change.
