It was a horrific scene that was captured on a video: a torrent of water, clay and rocks move to the village of Himalayas in Darali with this force that knocked on the buildings from its foundations and buried their homes to their roofs in a moment.
In a video distributed on social media and checking CBC News, you can see the residents in the state of Autarantuz in the northeast of the state of Auttarchal trying to escape when the torrent fell from the mountains on Tuesday.
Estimate 360 million cubic meters of debris I was in the village within seconds.
By the end of the week, Dozens of people were still missingWhile officials confirmed at least six deaths.
It is the seasonal wind season in India, but experts achieve whether it is a phenomenon known as the cloud – sudden and intense rain in a small location – caused the disaster or if it was brought in a ice lake breach.
While India officials are facing a violent reaction to the development regulations that may have worsened, scientists say that the climate change caused by a person increases the possibility of more catastrophic events like this.
“The trauma and intestine” to find out what happened in Darali, “climate scientist Raju Mortuzdandi said in an interview with Mumbai.
He says India has some of the highest mountains in the world, but the societies that were “living there in peace” for decades are now more vulnerable to disaster because of climate change.
Here is what we know about what happened in Darli and the factors that may have led to the disaster.

Where is Darali?
Dharali is more than 350 km northeast of the capital of India New Delhi.
It is located 2600 meters above sea level, along the Bahajerithi River, on the slopes of the Himalayas in the state of Uttrantic, in the northeast of the state of Uttrantal.
It was home to less than 1000 people before the disaster.
It is a local tourist spot and a stop for the Hindu pilgrims climbing to the city Indian ExpressDharali and other nearby societies held a religious festival this week.
Several homes, hotels and other buildings were built on both sides of another river flowing Seven kilometers below From the end of the ice river, at an altitude of 6700 meters, to empty in Bahjirathi.
In recent years, other places in the state of Uttrangal have seen similar disasters – but even more deadly. Up to 6000 people June 2013 When severe rains cause floods, landslides and the collapse of the ice lake near the mountainous town of Kedarnath.
Then in February 2021Nearly 200 people died in a nearby area when part of my ice broke out, causing ice collapse of ice, rocks and water that sparked floods along the river valleys below.
Was it a cloud – and what is this exactly?
Early reports on the disaster suggested that the cloud may have occurred in the area.
This is when warm and moisture air is forced from a lower height on the mountain slopes where it is mixed with cold air and creates a huge storm cloud.
Moisture drops expand in the cloud, and form new drops such as Strip Drops of fall.
When the cloud no longer contains water, it explodes, quickly releases a huge amount of rain – at least 100 millimeters per hour on an area of 20 to 30 square kilometers below – causing floods and ground collapses.
Some meteorological experts say that the amount of rain that fell in Darli and other places in Uttarkand on that day was Not enough To suggest the cloud.
Mortuz, a faculty member at the Indian Institute of Technology Kanbur and Fakhri Professor at the University of Maryland, a member of the teaching staff at the Indian Institute of Technology Kanbur and Fakhry Professor at the University of Maryland, said that there were no cloud screens in that region and the rains may be larger in higher altitudes.
“Therefore, we do not have data yet and we may not face it any time soon,” he said.
Mortanhouf says that the weather style that brought heavy rains to the area could have been a worker in the Darli disaster.
He says that the seasonal wind season in the Indian subcontinent is fueled by the warm air from the Arab Sea. But climate change contributed to the high temperatures in the Middle East and the Mediterranean region, which “pulls” the hottest air to the north and “pumping” more moisture into the slopes of Himalayas.
He says that this is not only to bring more rain, nor also contribute to the melting of the ice rivers and the creation of additional ice lakes.
The mother and father tells the moment in which they learned about the flood and the landslide that struck the village of Himalayas in Darali on Tuesday – and how they spoke with one of their children before losing communication and did not hear again.
Did a ice lake collapsed?
Another potential reason for the overwhelming flood and landslide in Darali is known as the flood of the ice shell.
“Floods of the huge ice lake that constitute a mixture of ice, sediments and rocks that can have catastrophic effects not only on infrastructure but loss of lives,” said Rodrigo Naro Perez, an assistant professor at the Earth, Environment and Society College.
He explains that the ice lakes are kept by natural dams, known as Moriaines, which can consist of ice as well as loose deposits and rocks.
He says that there can be different factors that cause the natural dam failure and unleash melting water.
In some cases, pressure from rain breaks Moriaine, or a large mass force, such as ice breakdown or landslide, can destroy the curse.
In Darali, he says, it may have been a mixture of the two.
Naro Perez says the Himalayas is at risk of this. There are 7,500 ice lakes in the Indian Himalayas, and the total size of them – 50 percent in 30 years, According to the 2020 study.
But he says that there are only monitoring systems 190 which is high riskLeaving the possibility of early warning and the possibility of saving lives.
It refers to another disaster in Switzerland, in May, where a rock slipped from my ice Burn 90 percent of the village From Blatten.
He says that the difference is that there was an early warning system in place and that officials had evacuated the village a few days ago. only One life Disputed.
“It is a numbers game,” he said. “In the past two years, we see the number of ice lakes increasing dramatically – not only in number, but also at the sound level.”
A large part of the ice river broke out in the Swiss Alps, and sent an increase of ice, clay and rocks that collide with Putin. Officials say the village of Al -Jabal was evacuated at the time, but one person is missing.
How much is the climate change?
There are many variables that led to what happened in Darali, a fellow in the Department of Earth Sciences and Climate Change in New Delhi.
He told Reuters that the effects of humans, such as the removal of forests and land management, may also be a factor in this disaster.
Others criticized the local government of relaxing construction regulations and allowing development along the river bed.
But regardless, Singh says, these disasters are increasing in frequency and density, and “can be attributed directly to changing climatic conditions.”
Even if there are effective warning systems and in place, “the danger is never zero”, as it gets worse with climate change, says Murtugudde.
He says adaptation may be a local concern, but global warming requires international cooperation.
“The rich and the poor are no longer important … global warming does not create any winners,” he said.
Heavy rains brought clear floods to northern India, washing homes and leaving more than 100 missing people.
