The SLCB tunnel collapse in Feb. 2025 is among worst dam-tunnel disaster this year in India. The incident occurred just four days after resuming tunneling work after a long halt killing at least 8 workers. Despite, two-month long multi agency search operation only two bodies were retrieved while mortals of six still remain buried inside the tunnel. The TBM involved in tunnelling has also been damaged. Given risky situation the rescue work was stopped in April end and there is no update on the same so far. Nearly 10 months after the disaster, there is no official report probing the reasons and addressing the concerns over inadequate geological, geotechnical inspections.

Central India’s Upper Ken Basin, where the ancient Bundelkhand Craton meets the younger Vindhyan sedimentary rocks, appears at first glance to be a quiet and time-worn landscape. But new research reveals that the region is still being shaped by deep, hidden tectonic forces. In a recent study, geographers Kundan Parmar and Satheesh Chothodi used high-resolution elevation data and underground gravity measurements to decode the subtle fingerprints of active deformation imprinted onto the basin’s rivers and valleys. Their findings show that ancient faults, modern uplift and slow tilting continue to steer the paths of the Ken, Sonar and Bearma Rivers (all part of Ken Basin), creating steep drops, shifting channels and asymmetric basins.
