Uttarkashi Tunnel Rescue

The Uttarkashi Tunnel incident occurred at the Silkyara Tunnel on 12 November 2023, trapping 41 workers inside. The primary cause behind the collapse appears to be a lack of proper care and safety measures. Arnold Dix and his team were actively engaged in rescue efforts, employing various methods. Micro tunnelling was being utilized to access the trapped workers. The workers were waiting inside the tunnel for rescue, with limited access to food and water. The initial step involves digging a vertical shaft from the top of the hill down to the tunnel to reach the trapped individuals. The day after successfully rescuing 41 workers trapped inside a tunnel in Uttarakhand following a 17-day operation, tunnelling expert Arnold Dix expressed his intention to return to the makeshift temple outside the tunnel. He mentioned the need to go back there to say thank you. He said the success of the rescue operation of the trapped workers was a ‘miracle.’ In an interview, while talking about why he prayed at the makeshift temple of local deity Baba Bokh Naag Ji, he said,

I have to go to the temple because I promised to say thank you for what happened. If you haven’t noticed, we have just witnessed a miracle.” [3]NDTV
