A group of nine tourists - some eportedly from Siberia’s largest university - hit by tragedy on the South Chuya mountain ridge.
The group was struck by an avalanche two days ago, 11 am on 6 May, but the two female survivors did not have the means to report the tragic accident.
The news only broke when the two young women met another group of mountain climbers who contacted local rescuers.
The climbers, some of them postgraduate students from the Novosibirsk State University - left a village of Kosh Agach on 1 May, aiming to spend two weeks in the wild.
The tourists were registered with the local Ministry of Emergencies as ‘Group 37’.
Eight rescuers are flying to the avalanche site now.
offre Peak: a significant rock avalanche in Canada
On Monday morning (13th May 2019) at 07:41 am local time, a significant rock avalanche occurred at Joffre Peak in British Columbia in Canada. This has been well-reported in the local newspapers – for example, City News 1130 has a good report, including links to seismic data that recorded the event. Chris Christie posted this image of the source of the landslide and the initial part of the track:-

Dr Drew Brayshaw has undertaken an initial analysis of the landslide, and tweeted that the failure area was about 25,000 – 30,000 m², based on a failure geometry of a block approximately 200 m high and 150 m wide. The runout distance was about 4.2 km. The location is 50.343, -122.446 if you want to take a look in Google Earth. The landslide is likely to have entrained a large volume of material along its track, although we will need to wait for good satellite images until this can be determined properly. No lives have been lost, but there has been some disruption to power supplies.

Once again we see a large rock avalanche in a high mountain area in the spring time, so it is logical to think that this might have been associated with melting ice in the rock mass. Interestingly, British Columbia has been experiencing unusually high temperatures – on Thursday last week a number of temperature records were broken, with temperatures in some locations reaching 30 C.

British Columbia experiences frequent large landslides – notable events include the 2012 Johnsons Landing landslide and the dramatic 2010 Meager Creek rock avalanche.

It’s in the story but 2 men where killed while filming a Disney movie there in 1957

Snip 4-5 minute Read Maps Statistics:
A total of 299 destructive avalanches were recorded over the winter with 19 deaths, according to an end of season report
Switzerland's WSL Institute for Snow and Avalanche Research, SLF, released its figures to the end of April in its Winter Review published this week.

It counts a destructive avalanche as one which leads to loss of life, injury or damages property.
All but one of the 19 people killed were participating in winter sports in unsecured terrain, classified either as backcountry (16) or off-piste (2).

The exception was a ski patroller who died on an open ski run when a huge slide swept across a piste in Crans Montana in February, as we reported at the time:
The deadliest single incident was the avalanche near Fieschertal in the Bernese Alps at the end of April which killed four ski tourers:
The 20-year average for deaths over a six-month winter period is 21.

The report describes a cluster of six fatal accidents in the western part of the northern flank of the Alps as 'striking'.

Either UBC or UofC did a comprehensive study that downgraded some of the original study findings (as recalled) due to sample conditions. Here is one of the original studies (abstract):

The effectiveness of avalanche airbags

Asphyxia is the primary cause of death among avalanche victims. Avalanche airbags can lower mortality by directly reducing grade of burial, the single most important factor for survival. This study aims to provide an updated perspective on the effectiveness of this safety device.
A retrospective analysis of avalanche accidents involving at least one airbag user between 1994 and 2012 in Austria, Canada, France, Norway, Slovakia, Switzerland and the United States. A multivariate analysis was used to calculate adjusted absolute risk reduction and estimate the effectiveness of airbags on grade of burial and mortality. A univariate analysis was used to examine causes of non-deployment.
Binomial linear regression models showed main effects for airbag use, avalanche size and injuries on critical burial, and for grade of burial, injuries and avalanche size on mortality. The adjusted risk of critical burial is 47% with non-inflated airbags and 20% with inflated airbags. The adjusted mortality is 44% for critically buried victims and 3% for non-critically buried victims. The adjusted absolute mortality reduction for inflated airbags is -11 percentage points (22% to 11%; 95% confidence interval: -4 to -18 percentage points) and adjusted risk ratio is 0.51 (95% confidence interval: 0.29 to 0.72). Overall non-inflation rate is 20%, 60% of which is attributed to deployment failure by the user.
Although the impact on survival is smaller than previously reported, these results confirm the effectiveness of airbags. Non-deployment remains the most considerable limitation to effectiveness. Development of standardized data collection protocols is encouraged to facilitate further research.

Some of the future findings were more comparative of data from Europe to North America. Basically, it comes down to whether or not it is alpine or sub alpine data, with Europe being predominantly alpine (above treeline) that favored increased survival rates and not so much in North America with more mixed alpine/sub alpine conditions.

Some North American practitioners will not wear them while others do. Here are the reasons as discussed with people (and the latter data speaks to this).

Alpine - generally allows the avalanche victim to stay afloat to some extent and ride the surface layer more easily avoiding deep burial (also with the added possibility that an air pocked is created if buried and the air in the pack can be released - usually you can't hardly move a cm anyway).

Alpine to sub Alpine - this may be true of the start zone if alpine yet can quickly end once the practitioner enters mixed terrain due to impacts with terrain objects (rock/ice/trees). In this latter description, practitioners of sport in this category may prefer to ride in the flow (like a river) as it tends not to interface with objects (takes the path of least resistance) whereas if riding the surface they can get thrown around into objects.

So, in one case (alpine) it is increased asphyxia due to being burred without a avalanche pack and in the other it is blunt trauma with a pack (although asphyxia is somewhat less).

Overall the concept is sound, however (and this is true of people moving to ski helmet (sounds like a no-brainer) protection) does it change their perception of risk and create more risk taking?

The best protective measure is awareness; learning some snow science and avoiding conditions intermixed with hazardous terrain, imo.
‎January‎ ‎15‎, ‎2020‎ - Search teams aided by Pakistani troops pulled out 21 more bodies from homes destroyed by this week's avalanches in the disputed Himalayan region of Kashmir, raising the overall death toll due to severe winter weather to 160 for Pakistan and Afghanistan, officials said Wednesday.

The worst affected area was Kashmir's Neelum Valley, where the 21 bodies were retrieved, said Ahmad Raza Qadri, a minister for disaster management. He said that since Sunday, 76 people have been killed in Pakistan-administered Kashmir in weather-related incidents. Another 45 people were killed in Pakistan's southwestern Baluchistan and eastern Punjab provinces.

Avalanches are common in Kashmir, which is divided between Pakistan and India and claimed by both in its entirety.

A 14-year-old boy is recovering after he was buried under five feet of snow that slid off a roof at his home near Truckee on Wednesday night.

Truckee Fire Protection District says the teen was playing in a snow cave next to his home when the snow slide happened.

Authorities say no one saw the incident happen, but when he didn't come inside after a few hours, family members looked for him, couldn’t find him and called 911.

Arriving crews immediately suspected a roof avalanche and began probing the debris at the bottom of the roof. When they hit something, they started digging and recovered the boy alive. (Truckee Fire Protection District contributed to this report.)

Incident details include images
A scary incident took place on Sunday morning, when an avalanche came down onto the road on Colorado's Berthoud Pass, burying 10 vehicles in the process. Also known as Highway 40, the route was closed between Robins Roost and Henderson Mine Road as a result. As of Monday morning, this portion, located south of Winter Park Ski Resort, remains closed.

According to the Colorado Department of Transportation, there were no reported injuries resulting from the slide, which took place at about 11:20 a.m. Vehicle and people who were trapped inside did need to be dug out, which took about an hour for the 'all clear.'

Footage from the scene shows that avalanche debris was deep enough to reach the top of vehicles that were caught in the slide.

Berthoud Pass is a route where avalanches can be a concern, especially during periods of heavy snow. Signage warns of the risk along this highway, which tops out at about 11,300 feet of elevation. The route leads to multiple ski areas in Grand County, consisting a steep grades and numerous switchbacks. It is not a route to take lightly in the winter.

Avalanche risk remains high around much of Colorado's mountainous terrain. The Colorado Avalanche Information Center had posted warnings prior to the snow that's rolled through the state in recent days.
