Villagers in East Pangu, in the Kuruv panchayat of Kollathur, Kerala, have reported a persistent low-frequency sound coming from beneath the ground for four days, prompting a joint inspection by local officials and utility authorities. The unusual noise, heard near the small plot owned by Thachaparamban Cheriyappuhaji, unsettled neighbours and led to calls for immediate investigation.
Underground noise in Kerala prompts local probe
The panchayat president, Salaam Master, accompanied by secretary Vishnu Shashi, vice-president Moyikal Sulaikha, ward members and other officers visited the site yesterday morning. Residents described intermittent rumbling that was loud enough to cause concern but not linked to any visible surface disturbance.
Officials informed the revenue department and summoned representatives from the regional water authority for a technical assessment. Revenue and water authority teams conducted on-site checks to identify potential sources. After inspecting nearby infrastructure, the water authority focused on a section of pipeline that runs beneath the area as a likely cause.
Investigators determined that a blockage in the pipeline had altered the flow and generated the noise. To test the theory, technicians cleared and then operated the pipeline, allowing water to flow through the segment. Panchayat president Salaam Master said the sound diminished after the work was carried out, lending weight to the assessment that the buried pipe caused the disturbance.
“We have informed the revenue officials and worked with the water authority to resolve the likely cause,” Salaam Master told reporters. “The noise reduced after the pipeline issue was addressed, but we will continue to monitor the site and carry out further checks if residents hear it again.”
Local residents welcomed the prompt response by civic leaders and utility teams, though some said they would prefer a more detailed technical explanation and a long-term plan to prevent recurrence. The panchayat has assured residents that further investigations will be undertaken if the sound returns or if any structural concerns are identified.
Such incidents, while primarily a local civic matter, raise broader questions about the condition of ageing subsurface infrastructure in rural areas. Blocked or damaged water lines, air pockets, and changes in underground water flow can produce noises that travel through soil and are audible at the surface. Authorities stressed that there was no immediate sign of danger to public safety in this case.
For now, the water authority will continue periodic checks and maintain communication with the panchayat. If the sound resumes, officials said they will commission a more extensive technical survey, which may include ultrasonic testing, pipeline pressure analysis and a review of recent maintenance records. Neighbouring households were advised to report any fresh occurrences promptly to the panchayat office.
The incident underlines the value of coordinated local governance and rapid mobilisation of technical teams when unusual local phenomena occur. It also highlights the need for routine inspection and upkeep of essential buried services to avoid disruption and community anxiety.
Key Takeaways:
- Residents of East Pangu, Kerala, reported continuous low-level sound beneath the ground for four days.
- Local panchayat leaders and revenue and water authority officials inspected the site; initial checks pointed to a blocked water pipeline.
- Authorities cleared and restored flow in the pipeline, after which the noise subsided, and further monitoring will continue.
