Incessant rain over the last few days across Nagaland caused inundation of many low-lying areas in Dimapur and Niuland districts and overflow of streams and landslide in Kohima.
In Dimapur, downpour during the past 24 hours led to waterlogging across low lying areas of the city disrupting normal life and traffic snarl till noon on Saturday.
Even the level of the Dhansiri river crossed previous level of decades and threatened some buildings whose foundations were constructed perilously at the river edge. The unprecedented downpour between 1am and 5am Saturday, left several low-lying areas inundated such as localities and roads in Half Nagarjan, Super Market, Walford Colony, Burma Camp, Dhobinala, Sachu Colony, and Marwari Patti area.
In several places, waterlogging caused water to flow inside homes and shops forcing some residents to temporarily evacuate or move belongings to safer places.
At several pockets of the city, vehicles were stranded as they could not pass through partially submerged roads. Residents in the affected localities said they expected authorities to initiate long-term flood mitigation measures caused mainly due to poor drainage systems and blocked culverts during every monsoon season.
Sachu colony chairman, Ketousakuo, told Nagaland Post that over half of the residents in the colony were affected by the flood-like situation, with many homes inundated with two to three feet of water inside.
He said this was a perennial problem caused by narrow drainage since many RCC buildings have encroached the space.
Kohima: Incessant rains triggered the collapse of a retaining wall in Upper P.R. Hill Colony here on Saturday afternoon, damaging at least three vehicles.
The retaining wall, part of the Deputy Inspector General’s (DIG) office complex below the Police Headquarters (PHQ), gave way due continuous rainfall over the past few days.
The collapsed wall crushed three parked vehicles—a Gypsy, an Alto, and a Swift-belonging to local residents. Fortunately, no injuries were reported. All the vehicles were completely buried under debris and loose earth.
Police personnel and emergency workers were working till late evening, to assist in recovery operations. Excavators and manual labourers were deployed to clear the debris and extract the buried vehicles.
The incident has once again highlighted the fragility of hillside infrastructure in Kohima, particularly during the monsoon season, when the risk of landslides and structural failures increases significantly.
