Two warnings, zero action: Why Wayanad tunnel tragedy is a 'man-made disaster'

📌 Summary:

• Kerala administration issued two warnings (June 20 and June 25) to contractor Dilip Buildcon of the Anakkampoyil-Kalladi-Meppadi twin tunnel project to remove ~1 lakh cubic metres of soil piled up from tunnelling; work continued regardless

• The collapse near Meenakshi (Wayanad) killed 3, injured several and left 5 missing; Kerala's environment minister called it a 'man-made disaster because the warning was ignored'

• June 20: Wayanad district collector ordered temporary stoppage of work until soil removal; June 25: a PWD-led inspection with the District Disaster Management Authority, State Environment Impact Assessment Authority and Konkan Railway Corporation (KRCL, executing agency) flagged risk of soil piping and slope instability — the retaining wall and tarpaulin cover were deemed inadequate against water seepage; work-stop order followed on June 27

• Soil was not shifted because KRCL reportedly 'found no suitable land', even though the district administration had identified land near the site

• Contractor's defence: a 'natural calamity' — Wayanad received ~265 mm rain in 24 hours (9-10 times an average July rainy day; over one-third of Kerala's average July rainfall), amid IMD heavy-rain warnings; the project complies with approvals and is supervised by the Supreme Court-appointed Central Empowered Committee in the ecologically sensitive region

• Aftermath: Kerala paused the tunnel project a day after the tragedy

📝 Prelims Facts:

• Anakkampoyil-Kalladi-Meppadi twin tunnel is in Kerala's Wayanad district (Western Ghats); Konkan Railway Corporation is the executing agency

• Soil piping: subsurface erosion forming tunnels/cavities that destabilise slopes

• Central Empowered Committee: Supreme Court-appointed body overseeing forest/environment compliance

🔑 Key Term: Soil piping — subterranean erosion in which flowing water forms pipe-like channels under the surface, hollowing slopes and triggering sudden land subsidence/landslides
