Extreme rainfall event in the Darjeeling district: 04/05Oct2025 (Part IIIB - damage caused by 'non- fatal landslides')

 Non - fatal landslides

The intense storm of 04–05 October 2025 triggered numerous non-fatal, rain-induced landslides of varying types and magnitudes across the Darjeeling–Kalimpong region (see above). Official estimates place the number of landslides in Darjeeling district alone at nearly 500. Given the scale of the event and the difficulty of surveying each site, this report focuses on a selection of the major landslides.

Seeyok Tea Garden - Sukhia block.

a. Area involved: Goddam dhura Ward 10 consists of 336 people in 87 homes.
b. Circumstances: Heavy rainfall began across the region on the evening of 04 October 2025. As the intensity increased, several residents—most of them tea garden workers—woke their neighbours and urged them to move to safer ground. One woman, an ASHA worker who had received RED alerts on her mobile phone, also went door-to-door warning others of the danger. Around 2 a.m. on 05 October 2025, a massive landslide struck, accompanied by a deafening roar reminiscent of an explosion. The Rangli River, normally a small stream, had swollen into a torrent, altered its course, and swept away two bridges in the area.
c. Damage: 7 homes completely damaged, 3 partially damaged. Livestock has been lost and vegetable gardens are ruined. Roads in the area are in a mess. 32 people were living in a relief camp. Many vehicles and two wheelers belonging to the community were washed away.

no one died - in large part due to the alertness of the community and timely evacuation to safer ground.
The tea industry, both in the Dooars and the hills, suffered huge losses because of the heavy rains. Here you see large landslides ruining parts of a garden - Goddam Dhura is visible in the valley below.

Taba Koshi, Mirik Subdivision (Coords 26.921391N 88.173500E)

a. Area: Taba Koshi is a series of around 40 homestays along the Rangbangh river which came up during the time of Subash Ghisingh and which started flourishing once road communication links from the area to Siliguri, Mirik and so on were established.
On 04Oct2025, due to the festive season, almost all the homestays were full with tourists from the plains.
b. Circumstances: As in other areas, rainfall started during the day on 04Oct2025 but intensified after 6pm and became really heavy later. Noticing the Rangbangh river had started crossed all danger levels, the locals started evacuating their guests to safer places after midnight. The power supply which had been erratic, thru the day because of the intense lightning on 04Oct2025 went OFF altogether at night so everything had to be done in pitch darkness and in heavy rain. So it was nothing short of a miracle that no one died.
c. Damages/loss: Many of the homestays were damaged as the Rangbangh river surged into the compounds and swept away vehicles as well as parts of the homestays in the early hours of 05Oct2025. There was significant damage to roads as well as to power lines and poles.

The Rangbangh river seen here is by all accounts a tiny stream which on the 05Oct2025 became a roaring torrent after the heavy rainfall on 04/05Oct2025. The river changed its course and threatened many homestays which were otherwise quite far from the river. Here, an earthmoving equipment is being used to correct the river's path.
The rampaging Rangbangh river caused extensive damage to roads and bridges at Taba Koshi on 04/05Oct2025.

Damaged parts of a homestay and power lines at Taba Koshi, Mirik.
On 05Oct2025, a tiny stream (Rangbangh river) transformed into a rampaging torrent and brought down these massive boulders to a homestay at Taba Koshi.
This is the heart of tea country in Darjeeling district and the havoc wreaked by the rain and ensuing landslides is huge. Large parts of tea gardens have been severely mauled by the disaster o 04/05Oct2025.

Rainfall data of July 2024 of some towns in Sub-Himalayan W Bengal and Sikkim

IMPACT OF THE JULY 2024 RAINS AT TEESTA BAZAR:
Some young men at Teesta bazar had started a two wheeler repair business in this shop on the Darjeeling-Kalimpong road after they shovelled out all the sand and debris brought in by the 04Oct2023 disaster (notice the damaged ceiling fans). The rains of July2024 put an end to their business venture and dreams when the Teesta river, flowing in the vicinity and almost at the same level flooded their shop again during heavy rains.


Rainfall normally peaks in July during the monsoons after which the rainfall gradually declines in August and Sept with the monsoons normally exiting our region in October.
As is clearly visible from the top data, rainfall was heavier in the Dooars area and foothills of Kalimpong district (and Bhutan hills).
IMPACT
The amount and intensity of rainfall impacted road communication a lot with NH10 and the Darjeeling - Kalimpong road being closed OFF and ON thru the month.
Even Rohini road to Darjeeling from Siliguri was closed for some time on 02Jul2024

                                Landslide near Loreto School, Darjeeling - 05July2024

INFACT NH10, WHICH HAD CLOSED ON 01JULY2024, COULD NOT BE RE-OPENED FOR TRAFFIC UNTIL 31JULY2024 - WHICH WAS THE LONGEST DURATION THAT THE HIGHWAY WAS CLOSED CONTINUOUSLY EVER - ALL DUE TO THE TEESTA VALLEY GLOF OF 04OCT2023.

Photo essay on Glacial Lake Outburst Flood (GLOF) of 04Oct2023: the Kalimpong chapter

The GLOF of 04Oct2023 from Lhonak Glacier affected down stream areas in Kalimpong district (W Bengal) as well. As on date, three people are confirmed dead and thirteen people missing, most of these figures coming from the W. Bengal side of Rangpo.
However, many of the low lying areas along the path of the river were severely affected and residents of Teesta bazaar recounted how a swollen river had suddenly barged in, in the darkness and in pouring rain at around 3am on 04Oct2023.
Kalimpong recorded 147mm rain on 04Oct2023.


On 10Oct2023, we (Praveen of Junkeri Studios, his team and I) reached Teesta bazaar which is around 15kms from Kalimpong and spent almost 6hrs there and at Melli and Bhalukhola (See map above). We could not see other places such as Geil Khola or Tribeni because the roads are simply non existent:
* Road towards Siliguri - damaged at Rabi jhora and Likhu bhir. *Road to Darjeeling and Teesta bazaar - still under Teesta waters at the NH10, Darjeeling road bifurcation.* Road to Tribeni damaged at numerous places from Teesta bazaar to Tribeni. * NH10 towards Gangtok - precarious at many, many places, even tho it was open at that time.
Relief camp details as on 11Oct2023 are given above. Many more are staying with their friends and relatives in the vicinity.
Loss of livestock also has been a major issue with countless pigs, cattle, poultry and goats being swept away by the floods.
What struck us on reaching Teesta was the sheer size and swiftness of the river even after 6 days of the GLOF and the amount of debris/sand and sediment the river was still carrying.I wondered how this was possible? since it was not raining heavily in North Sikkim.
This is the road to Darjeeling at Teesta bazaar.
With the river still flowing from one bank to the other and at much higher level (because of the silt deposit), parts of the road to Darjeeling are still submerged.
A dog lazily scratches himself, while sitting on the roof of a home which is still under water at Teesta bazaar. We were told that 45 homes had been damaged or destroyed in this area. Notice the water level is almost at the same level as the road. We observed this everywhere - the water level has gone up dramatically, even as much as 20-30 feet and now the river is flowing much closer to populated areas and the railway tunnels.
Sunayana Devi stands on the roof of what was earlier her kitchen. Half of her three storey structure is now filled with sand and the sudden invasion by the flood waters prevented them from saving anything. Like many so many others we spoke to, she wants the government to relocate her to a safer place.

The ferocity of the flood waters is unimaginable - the Teesta dumped 10-15 feet of sand on these two vehicles (and everything else) in its 3 hour rampage at the center of the bazaar. We were lucky this time - our casualty figures are far less than what was expected.
Volunteers clearing up in Teesta bazaar take a break from their work - photo by Praveen.
Remains of a brand new resort in Teesta Bazaar after the GLOF. Huge chunks of whatever is seen in this image are cracked and dangerously tilting towards the river - photo by Praveen.
Even though not many lives were lost, the GLOF wreaked havoc on the infrastructure in the 3-4 hour event. All this comes at a time when people of this region are looking forward to celebrating the festive season ahead - photo by Praveen.
A priest and a devotee perform a puja on the banks of the Teesta perhaps to pacify the river Gods. The river looks deceptively calm.
Fresh rations stock at Melli bazaar (W Bengal side).
The worst affected here were the two shanty colonies (located below the Melli bridge) which comprised of almost 30 odd homes. Nothing remains except a solitary, sand covered Masjid where the the predominantly Muslim dwellers used to worship.
As with others, a victim wanted the government to swiftly shift them to a safer location.
At most places we visited, there was no shortage of food or clothing for the time being - but winter is nigh and these people will need sustained care to help them recoup.

Teesta stomps into the courtyard of the Tribeni Covid Hospital.
This large structure was used as the GTA Covid Hospital during the pandemic and is extensively used by tour operators to entertain tourists even overnight. Luckily no one was around when Teesta came calling on 04Oct2023 at 3am.
One can see quite a lot of damage in the right flank of the building in the drone image by Praveen (below).
NH10, opposite Melli town.
The GLOF of Oct2023 together with the dam operations is going to make NH10 maintenance a headache. Numerous places along the NH10 are subsiding and this makes driving at night on the highway even dangerous.
Another image by Praveen of the damage to NH10 is below
The UCNI church at Bhalukhola, near Melli. This is low lying area which was flooded during the GLOF.

There was a shanty colony here in Bhalukhola, which has been swept away by the flood. The more permanent structures have survived but will need extensive repair.
But looking at the proximity of the river and the elevated level at which it is flowing, will anyone risk returning to these homes? Photo by Praveen.

An after thought and a sense of deja vu
I find it strange that on 10Oct2023, I did exactly the same thing I did from the same spot, 55years ago in Oct1968 - that is, photograph the devastation caused by a raging river from the opposite bank of the Teesta.
I have written about it here
 
Update on 16Oct2023: Teesta-Darjeeling road open 'but repairs still going on', as reported by Mr Soam Namchu of Glen Family Foundation today in STH Whats App group 'Hazard Alerts'
