What are the reasons behind the collapse of the Silkyara tunnel and what are the challenges faced by the rescuers in the rescue operation
Rescuers set a 100-hour vertical drilling target on Day 15 of the Silkyara tunnel collapse.
The collapse of the Silkyara tunnel was caused by multiple factors, including:
- Heavy rainfall: The area experienced heavy rainfall, which increased the water level in the nearby river, leading to increased pressure on the tunnel walls.
- Poor construction: The tunnel was constructed using substandard materials and the engineering design was reportedly flawed.
- Lack of maintenance: The tunnel had not undergone regular maintenance, resulting in the deterioration of structural integrity.
- Unstable conditions: The collapsed tunnel created an unstable environment. Continuous falling debris and the risk of further collapse hampered the rescuers' progress.
- Inaccessibility: The tunnel's remote location and narrow passageways made it difficult for rescuers to enter and navigate through the collapsed sections.
- Limited resources: The rescue operation required specialized equipment and skilled personnel, which were limited in availability.
- Time constraints: The 100-hour vertical drilling target set by the rescuers added immense pressure, as time was critical in saving trapped individuals.
