Internal report warned of imminent Wayanad tunnel slope failure before deadly landslide

An internal geological assessment reportedly warned of imminent slope failure at the Wayanad tunnel project days before the landslide that claimed six lives.

Wayanad Tunnel

Six days before the Kerala government halted work at the Wayanad tunnel project, an internal geological report prepared by the project’s sub-contractor had reportedly warned that the slope above the tunnel’s north portal could fail at any moment under prevailing monsoon conditions.

The landslide struck the north portal of the under-construction tunnel in Wayanad on Tuesday, killing six people and raising serious questions over slope stability and safety measures at the site.

Report highlighted severe slope instability

According to the internal assessment prepared by Dilip Buildcon Limited (DBL), the sub-contractor handling the tunnel work, the hillside above the north portal had already begun showing signs of structural distress.

The report was jointly prepared by DBL senior geologist Raju Sagar, Geological Survey of India (GSI) official A. Ramesh Kumar and Authority Engineer Dr H.K. Singh from Turkish Engineering Consulting & Contracting.

The assessment covered inspections carried out between June 3 and June 11 at the north portal near Kalladi-Meppadi in Wayanad.

Engineers found that the slope consisted of nearly 35 metres of loose silty soil over hard rock. The report noted that this type of soil retains water during heavy rainfall, increasing its weight while reducing stability and making it vulnerable to landslides.

Despite slope protection measures including stepped cutting, shotcrete and soil nailing, engineers observed widening cracks, soil movement, muddy seepage and cavities developing within the slope.

Underground water flow raised major concerns

One of the report’s key findings was the presence of underground water flowing between two support levels inside the slope.

According to the assessment, such internal water movement could erode the soil from within, significantly weakening the hillside and increasing the likelihood of a sudden collapse.

The report specifically identified the left side of the north portal as carrying a much higher risk than the right slope and warned that, under existing rainfall conditions, it “may culminate in sudden slope failure at any time.”

Safety systems found to be inadequate

The report also pointed to shortcomings in the site’s safety infrastructure.

It found that several drainage holes designed to reduce water pressure inside the slope were either ineffective or not functioning properly on the high-risk section. It also noted that piezometers, which monitor underground water pressure and provide early warning of slope instability, had not yet been installed.

The assessment added that the existing monitoring equipment was not accurately reflecting the visible signs of distress observed at the site.

Blasting not identified as primary cause

Trial blasting for tunnel excavation was conducted on June 5, June 6 and June 11 while the slope was already showing signs of instability.

However, the report concluded that recorded blast vibrations remained within permissible limits and indicated that prolonged heavy rainfall, rather than blasting, was the primary factor behind the slope deterioration.

Engineers recommended multiple corrective measures

The internal assessment recommended several immediate measures to improve slope stability.

These included constructing gabion retaining walls along the vulnerable left slope, covering exposed soil with protective matting and tarpaulin, creating lined drainage channels to divert rainwater, and carrying out field tests to verify the effectiveness of existing soil nails and drainage systems under saturated conditions.

The report also expressed concern over the location of a nearby concrete batching plant, stating that its weight and heavy vehicle movement could further affect slope stability. It recommended relocating the facility away from the vulnerable area.

Contractor and project authorities respond

Project authorities said the report had primarily been commissioned to assess the impact of blasting activities.

An engineer associated with Konkan Railway Corporation reportedly said work at the north portal was stopped after the findings emerged.

The engineer maintained that shotcrete was used alongside 12-metre-long concrete anchor rods installed at two-metre intervals to strengthen the slope. He also claimed that the landslide occurring above the site would have been difficult to prevent through conventional safety measures.

When asked about monsoon preparedness and slope protection, project representatives said standard engineering practices had been followed. However, they did not provide a clear explanation regarding the status of gabion wall construction or whether there had been shortcomings in preparing the site for tunnel work.

The contractor also stated that delays in government land allocation for storing excavated soil affected project logistics.

Following the landslide, the engineer said nearly 200 workers at the project’s south portal left the site out of fear and that construction would not resume until an expert committee appointed by the Kerala government approved future safety measures.

The internal report was prepared days before the District Collector issued a stop-work order on June 20, indicating that work at the north portal had already been halted amid growing concerns over slope stability.

Himanta Sarma accuses Sonia, Rahul of provoking unrest over Vande Mataram row

Assam CM Himanta Biswa Sarma criticised Sonia and Rahul Gandhi over the Vande Mataram controversy and accused Congress of provoking unrest.

Assam Chief Minister Himanta Biswa Sarma on Monday criticised Congress leaders Sonia Gandhi and Rahul Gandhi over the controversy surrounding the rendition of Vande Mataram at the party headquarters in New Delhi on Independence Day.

Sarma questioned how the Congress would govern if it returned to power, alleging that the conduct of its senior leaders during the national song had raised concerns.

“During Vande Mataram, the way Sonia Gandhi behaved and the song was stopped midway clearly indicates that if Congress mistakenly comes to power, the country will face a worse situation,” Mr Sarma said.

The Assam Chief Minister also accused Sonia Gandhi and Rahul Gandhi of encouraging protests in the name of Gen Z.

“Sonia Gandhi and Rahul Gandhi have almost taken a decision to oppose the country in the name of Gen Z. They are provoking people to protest and trying hard to create a bad environment in the country,” he said.

Sarma further alleged that such actions could contribute to instability in the country.

“I am not bothered about these things, but these people are working against the country and provoking the people of the country to protest and bring anarchy,” he said.

What triggered the Vande Mataram controversy

The political row erupted after footage from the Congress Independence Day programme on August 15 surfaced on social media. The video showed senior Congress leaders, including Sonia Gandhi, Rahul Gandhi and Mallikarjun Kharge, during the rendition of Vande Mataram.

BJP leaders have interpreted gestures seen in the footage as an attempt to interrupt the national song. The Congress, however, has rejected that interpretation.

The issue has since become a political flashpoint, with BJP leaders accusing the Congress of disrespecting Vande Mataram.

A complaint seeking action against Sonia Gandhi and Rahul Gandhi over the alleged disruption is also being examined by the Delhi Police.

Air India drug test row: 2 more pilots fail preliminary screening

Two more Air India pilots have not cleared preliminary drug tests and have been de-rostered while their final test results are awaited, sources said.

Two more Air India pilots have not cleared the preliminary stage of drug testing ordered by the airline following the Phuket-Delhi flight incident. Their final test results are awaited, and both pilots have been de-rostered in the meantime, sources said.

The airline had directed its pilots to undergo drug testing as part of a new standard operating procedure after the pilot-in-command of the Phuket-Delhi flight failed two urine tests conducted after the aircraft landed. Marijuana was detected in his system.

More than 300 Air India pilots have undergone the testing process so far. Sources said final drug-test results generally take around 24 to 48 hours.

A cabin crew member on the Phuket-Delhi flight was also believed to have filed a complaint alleging that the pilot had previously smoked “pot”.

What happened on the Phuket-Delhi flight

The incident involved an Airbus A320neo that experienced a sudden drop of around 300 feet. The aircraft’s system data indicated a simultaneous loss of control of key flight surfaces, including the elevators and ailerons, for about four seconds.

The spoilers also lost control following the same hydraulic failure.

During the four-second period, the aircraft’s elevators and ailerons moved without pilot commands after multiple failures involving the jet’s three hydraulic systems.

The elevators control the aircraft’s pitch, while ailerons help control its roll. Spoilers reduce lift and increase drag, including during descent and landing.

Air India’s earlier statement on drug testing

The incident was initially reported as being linked to turbulence, before aircraft system data provided further information about what had occurred.

Air India had said it conducts regular drug testing of crew members in accordance with civil aviation regulations. The airline said the testing was part of its existing compliance process and was not initiated specifically because of the Phuket-Delhi flight incident.
