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.

CJP announces October 10 Delhi protest against Gyanesh Kumar

CJP leader Abhijeet Dipke has announced a protest at Jantar Mantar on October 10, demanding the resignation of Chief Election Commissioner Gyanesh Kumar.

Cockroach Janta Party (CJP) leader Abhijeet Dipke has announced a fresh protest at Delhi’s Jantar Mantar on October 10, saying the demonstration will be held if Chief Election Commissioner Gyanesh Kumar does not resign.

Dipke made the announcement after a CJP demonstration at Mumbai’s Shivaji Park. He called on people from across the country to join the proposed Delhi protest, describing it as a peaceful agitation.

Abhijeet Dipke’s October 10 protest call

In a post on X, Dipke said CJP supporters would march to Delhi and hold a protest at Jantar Mantar if Kumar did not step down. He also said that if Delhi Police stopped the protesters, the location where they were stopped would become their protest site.

The CJP leader had earlier warned of a larger agitation while addressing the gathering at Shivaji Park. He said that if the Chief Election Commissioner did not resign, the movement would expand to Delhi.

CJP’s allegations against the Election Commission

During the Mumbai protest, Dipke alleged irregularities in electoral rolls and questioned decisions concerning the election process. He claimed that 13 crore voters had been deleted over two years and alleged that voter deletions had affected electoral outcomes in several states.

These claims were made by Dipke while addressing the protesters and were not presented in the report as independently established facts.

He also alleged that voters were deleted from constituencies in Delhi, Tamil Nadu and West Bengal and linked these alleged deletions to election results.

The CJP leader further criticised the proposed simultaneous elections framework, alleging that the ruling BJP’s objective was “One Nation, One Election, One Party”.

CJP demands Gyanesh Kumar’s resignation

CJP leaders have been demanding the resignation of Chief Election Commissioner Gyanesh Kumar and have also called for criminal proceedings against him.

The group has criticised the Election Commission over the Special Intensive Revision of electoral rolls and has demanded changes to the law governing the appointment of Election Commissioners.

The Election Commission, however, has said that decisions of the three-member poll body, including those concerning the SIR exercise, were taken unanimously.

Protest at Mumbai’s Shivaji Park

The October 10 Delhi announcement followed a CJP demonstration at Mumbai’s Shivaji Park. The protest was held despite police denying permission for the event, according to the report.

Several groups and individuals participated in the demonstration. The Shiv Sena (UBT) had also extended support to the CJP’s agitation.

Dipke said the CJP would continue its campaign and called for the proposed October 10 demonstration in Delhi under the slogan “Chalo Delhi”.

MK Stalin attacks Vijay government over hindi signboard in Tamil Nadu

MK Stalin criticised the Tamil Nadu government over Hindi lettering on a State Highway signboard and warned the Vijay-led administration against interfering with the state’s two-language policy.

MK Stalin

The use of Hindi on a highway signboard in Tamil Nadu has triggered a political row, with DMK chief MK Stalin criticising the Vijay-led Tamilaga Vettri Kazhagam (TVK) government over the issue.

The controversy centres on a State Highway signboard that displayed place names in Tamil, English and Hindi. The board was installed on the Alwarthirunagari-Valliyoor State Highway 93 route through Sathankulam in Thoothukudi district.

Stalin objected to the inclusion of Hindi, saying Tamil Nadu has long opposed what he described as attempts to impose Hindi and warning the state government against altering its established two-language policy.

He questioned whether the use of Hindi on the signboard represented the kind of change promised by the TVK government. Stalin also urged the administration not to interfere with Tamil Nadu’s language policy.

Hindi removed from signboard

Following the controversy, the Hindi lettering was removed from the signboard. The state government also suspended two officials from the Highways Department over the matter and initiated departmental action against them.

According to officials, the Assistant Divisional Engineer and Assistant Engineer associated with the project had failed to inform higher authorities about the inclusion of Hindi on the board.

The Tamil Nadu government has said that the use of Hindi on the State Highways Department signboard was against the state’s two-language policy and warned that strict action would be taken against officials violating the policy.

Stalin targets Vijay government

Stalin also stepped up his criticism of the TVK administration, describing it as a “Reels government” and alleging that it was responding to social media trends involving influencers from northern states.

His comments came amid a wider political debate in Tamil Nadu over the state’s established Tamil-English two-language policy and the use of Hindi in government-related signage.

The latest controversy has therefore brought the language policy issue back into focus, with the DMK questioning the TVK government’s handling of the Hindi signboard and the state administration taking action against the officials concerned.

MK Stalin has criticised the Vijay-led Tamil Nadu government over Hindi appearing on a State Highway signboard. The Hindi lettering was later removed, while two Highways Department officials were suspended and departmental action was initiated.

700 detained as Delhi, Mumbai see protests against Gyanesh Kumar

More than 700 protesters were detained in Delhi during demonstrations demanding Chief Election Commissioner Gyanesh Kumar’s resignation, while thousands gathered for a separate protest in Mumbai.

Published

More than 700 protesters were detained in Delhi on Friday during demonstrations demanding the resignation of Chief Election Commissioner Gyanesh Kumar over alleged irregularities related to the electoral rolls and the Special Intensive Revision (SIR).

The AAP, Congress and Left-linked groups were among those participating in the protest at Jantar Mantar. Senior AAP leaders, including Atishi and Saurabh Bhardwaj, were detained by the police.

Police had denied permission for the demonstration and imposed restrictions in the New Delhi district. According to police, the protesters were taken to different police stations outside the New Delhi area and were to be released after necessary paperwork and legal formalities.

Why are protesters targeting Gyanesh Kumar?

The demonstrations have centred on the Election Commission and the SIR exercise, which has involved the revision of electoral rolls and the removal of voters described in the report as “inactive”.

The demand for Gyanesh Kumar’s removal intensified after reports that Election Commissioners Sukhbir Singh Sandhu and Vivek Joshi had objected to several decisions taken by the Election Commission.

The Election Commission has denied wrongdoing in the SIR process and said that differing views among election commissioners are normal.

Protests in Mumbai

In Mumbai, the Cockroach Janta Party held a large demonstration at Shivaji Park despite police denying permission for the rally.

Thousands of people gathered at the venue, with police deploying additional personnel and putting up barricades on routes leading from nearby areas. Protesters carried the national flag and placards demanding Gyanesh Kumar’s resignation.

The protest was held on the birth anniversary of Mahatma Gandhi. CJP founder Abhijeet Dipke addressed the gathering and described the demonstration as a tribute to Gandhi.

Protests reported in other cities

Apart from Delhi and Mumbai, demonstrations were also reported in Jaipur and Ahmedabad.

In Jaipur, AAP workers protested over the SIR process and clashed with police, according to the report. Senior party leaders later submitted a memorandum to the governor.

A demonstration was also held outside Gujarat University in Ahmedabad, with protesters demanding Gyanesh Kumar’s resignation.
