unless the e.u. and i.m.f. bailout cash into its collapsing economy. also gyptian is headed back to the polling station for the third and final round of the parliamentary election it's the first focus since president mubarak was toppled in february last year. coming up next the snowboarders and skiers who've seen and survived the dangers of an avalanche. the cooler peninsular in russia's north home to the q.b. massive mountain range this is the cold and windy bolshoi pass the snow here is between one and a half and four meters deep avalanche safety specialists are probing the snow structure on one of the slopes. the top layer of snow drifts on a slope is unstable and ski is could trigger an avalanche shift attention those of

you who are keen to scull mountain peaks please be careful. some avalanches a wet others a dry it all depends on the snows composition the speed of avalanches varies between seventy and four hundred kilometers an hour man can do nothing in the face of tons of snow rushing down to such a velocity. and yet people do live in the mountains they study avalanches to be able to protect themselves from the beaches skiers and snowboarders tempt fate by taking to the mountain slopes. in this weather station in the q.b. massive is situations close to the town of one hundred fifty kilometers north of the arctic circle it is one of the instruments of the avalanche safety service it

records dozens of readings of several times a day snow and ground temperatures wind direction solar activity and precipitation all those factors affect the snow and its structure the station staff uses them as the basis for political reform casts concerning avalanches. what triggers a sudden movement of snow in the mountains resulting in a formidable natural disaster. finding the answer to that question is the job of scientists to some petersburg's hydra me to relaunch a cool university one of the factors triggering an avalanche is nothing more unusual than snow evaporation little flakes turn into vapor even at very low temperatures. but with fiber in the top layer of the snow but he escapes into the year. but. it settles on large snowflakes turns into us. as a result snow in the lower turns into large round crystals. this makes

the top most slide over the ground pellets. the only way to fight avalanches is to get them to move before they begin sliding down on their own whenever a weather forecast points to snow instability avalanches are set off to prevent the risk of a larger one occurring before the roads are blocked ski routes are closed and the area was cordoned off a modern computer system controls avalanche movement gasses fed into a bell suspended from a helicopter an operator then triggers a spark in the belt on the gas explodes the shockwave triggers an avalanche.

this method is widely used in the foothills of the caucasus close to the city of sochi russia's most popular ski resort is situated here. for all mountains in the world are prone to avalanches and all of them are affected by our lunches every single one. yes the slope is avalanche prone if it is steeper than fifteen to twenty degrees. the two thousand and fourteen winter olympics is to take place here in new ski lifts are being built a modern trails are being prepared the downhill routes varying complexity some are just right for budding skiers others pose a challenge to professional sportsman. the caucasus mountains occupy an area about the same size of an average european country groups provided with all the necessary facilities take up

a small part of the slopes so far it is only possible to reach most of the mountain tops by helicopter going downhill where nobody. his set foot is the ambition of many skiers and snowboarders there is a special term for this costly form of entertainment kelly skiing. to get their wish her well being is what every free rider aspires to but it just takes your breath away to ride down the slope after a helicopter. flies you to some out of the way knock in the mountains.

national. once we've left the helicopter we have to test the snow in the air so what this means is well we make a pick to see the pattern of snow fall in the last few weeks. and see if we see that there's a danger of an avalanche happening that day then we just pack up straightaway and go home when the situation is just right though we follow this route down the mountain. or the wilds of the route the better the snow shore you have so many different routes lying ahead of you so you can choose whichever way you want to go down the mountain pending on the level of skiing your experience in english is how good you are at the new thing that. studying and forecasting avalanches is a complicated process with many phases any forecast supplied by the weather station can never be certain accurate conclusions are made only after testing the snow

cover at a particular point. you know one layer of the snow is compact the other is loose you can see it is fluffy. but you see if i touch this with my finger it is almost uniform i'm going to see how thick it is and there's twenty five centimeters of snow drift. snow drift is the layer that moves with the wind from one location to another this type of snow has the weakest bond with the lower layers. when somebody comes to the slope they see such snow but they don't know what it is like underneath it maybe packed in america case it is not dangerous but what if it is unstable down there you just step on the snow and it slides away from you if the snows temperature structure and density are all measured by the specialists to see how the layers bond together they handle the readings right on the spot it's.

the test demonstrates that the top layer of the snow drift on the slope is unstable so it may start sliding when skiis or snowboarders ride over it which could then trigger an avalanche so now we're going to designate the area as hazardous and closed to the public attention of those of you who are keen to scale mountain peaks please be careful according to the avalanche safety center a heightened alert has been declared for the next two days because of an avalanche hazard. or is a ski resort within the arctic circle originally it was meant as a place where the people of the town of kill lost could spend their vacations today tourists from across the country come to visit. this morning we were going there for ten days but trouble struck on the second. memories of what happened then are so vivid in young's mind that it seems as though it was just yesterday but in fact several years have passed since the accident in

many ways that incident changed his life. but if you look at the slope from below you will see a clearing between the trees this is it is there because frequent avalanches sweep away trees standing in their path i did not know at the time that the slope was avalanche prone. none of the people who came to that slope could even imagine the outcome. free riders make a special point of looking for wild slopes to ride over virgin snow. for the past ten years you have guinea cliff a cough has taken groups of free riders from the city of you to the mom i pass on

the southern shore of lake baikal. the lake in the air could screech in is the world's largest body of fresh water locals call it to see it is fifteen hundred meters deep in place it's. important will cover part of the distance over the ice of lake baikal and then it will be several kilometers of a winding path in the mountains another ten kilometers along a stream go which. you could say the place is in the wilderness there isn't any electricity or a decent road that can only be reached on the by snowmobile or on foot. on the way to its destination the group registers with the local rescue service. an official of the service and rescue party takes note of its roots the number of people involved and approximate date of the group's return if the group fails to

turn up on time rescue teams will undergo a search and rescue operation like all other groups of this kind this one is briefed before it continues its journey. i wish to formally warn you of possible avalanches in the mountains you should be on alert especially after lunchtime when warmer weather normally causes snow falls also a storm alert has been declared for tomorrow north westerly winds of up to twenty meters a second. a member of the rescue services joins the group they go as far as the foothills where the road ends they then cover ten kilometers across low hills with an all terrain vehicle but before taking a ride from the slope the group needs to hike uphill on force as no motor vehicles can get up such an incline.

heading toward slopes hidden from the sun because that's where pax knows likely to be if only i mean he may begin moving any time now that's why i will go skiing on the shady side close to the forest the snow still holds on. despite the long pole the group of three riders managed to scale the mountain and go downhill on the first day before some so. i want.

cola peninsula within the arctic circle is russia's northernmost point of sportsmen skiing in the mountains has been hit by an avalanche rescue as of the carroll school regional rescue services receive request for assistance they do not know how long it will take them to reach the scene a lot depends on distance the terrain and weather conditions they have vivid memories of what happened to a group of skiers from some peaches both a few years ago. is one of those who know old sue well the full force of an avalanche feels like. as i approached the edge to get ready for the descent. i was knocked over with such force that my gloves and hat instantly shot off and everything became unfastened. i sensed i was tumbling down at top speed with an enormous mass of something pressing on me it was like being under

a stamping press quick but i cannot say how long all that lasted but i was told the avalanche was on the move for only four or five seconds but to me it seemed like an eternity was enormous blocks of snow and ice reduce everything in their path to smithereens they sweep away trees and destroy buildings at one point i felt as if i was literally bending over backwards with the stress on my spine was so great i thought my back would be broken. then my head was out of the snow. i think my lungs had filled up with snow and i strained to cough it up and i remember feeling afterwards that my chest had become lighter. yann was dug up by a companion who had not been caught up in the avalanche rescuers found three more men buried under the snow they were dead quite often it takes several days to find victims buried in an avalanche for me to long proops they used to dig into the snow

this is the only method to find a free rider unless he has a radio beacon on it. when the probe hits something soft it's clear that it's a victim the sound produced by the probe in that case is also helpful. so we begin digging right there and then fairly sure is a doctor with the local rescue team he always joins the team on duty when they go to help avalanche victims his eight kilogram kit contains all the necessary equipment for on site reanimation though in practice he rarely needs it. before committing to statistics if victims are stuck in an avalanche be fifteen minutes their chances of survival of fifty percent any longer and there is a sharp drop in the chances of survival in the ability of the wolf we haven't recovered a buried survivor from an avalanche around here in the past ten years. intense preparations for the winter olympics have cut the number of urgency lopes in the

vicinity of such a label for free riding the results rescuers will be hard put to recall the last time they dealt with avalanche related incidents. and ten ice to counter the snow on the mountain slopes they are the visible part of what is otherwise covered with snow these are ultimately weather stations days or is continuously supplied to an online computer of the resort's avalanche control service. the station measures snow depth temperature humidity wind characteristics solar radiation planned and is very precious with this and more allow us to forecast avalanches put you in the proceedings here including. these odd looking pipes on mountaintops a part of the results of a safety system. failing to so-called shelters booths containing gas cylinders with

oxygen and propane. more assured no k. everything's in order here for shelter oxygen and propane is fed to an empty avalanche gun through special pipes and operators sets off the gas mixture by pressing a button. in the old days all resorts use guns or mortars to fight avalanches they would be brought to a slope and fired at a designated target nowadays they're gradually falling into disuse. we have resolved the problem by taking on purely ecological systems used elsewhere in the world. they don't damage the ground either in summer or in winter. they simply remove the snow whenever we want to get rid of it back or get out on the other a computer at the avalanche control service receive signals from automatic weather

stations twenty four hours a day irrespective of weather conditions the figures are then analyzed. if necessary the operator uses the same computer to set a small avalanche in motion which cannot do any harm. which as we say any slip compose an avalanche has a way. avalanches make even in the most unlikely places that. police skiing enthusiastic take every possible precaution but they can never be fully guaranteed against being caught in an avalanche. and the thing that is that when you get on the fresh snow it's already under stress but you make things worse by adding your weight to it on top of that is you cutting the snow with your skis and all my combined might set off an avalanche. normally the guide will do the job himself of testing the snow and if he senses the

possibility of an avalanche he might deliberately force the snow to get in the thing. if the bit it's a boy if you cut into the snow in front of that doesn't mean it won't snap behind his trudel first break up front by little crank behind you to you no matter whether you've done the cutting or somebody else has done it for ya. if you know what it is the political. scientists in some petersburg research the peculiarities of the mountains ice and snow there is also surprising as it turns out an ice rupture generates a radio wave the can be located. i mean the most interesting thing about it is that radio frequency emissions take place shortly before i sharing. this means it's possible to full cost as well as record i should. remember this can be done if only for a short time before just an hour or so. experiments with snow by the scientists

have also demonstrated that during at slight an avalanche to them it's radio waves . radio missions are generated by small snow crystals rubbing against one another as a resemblance pointing to the existence of radio frequency radiation even in a visible range people have seen light coming from nighttime avalanches were delivered. to the time being it is possible to focused avalanches only a few seconds ahead special radio receivers they used for the purpose. mounted on my on the southern side of lake baikal is known for its fluffy snow it is light soft and powdery freeriding fans need to demonstrate highly professional skills in such conditions otherwise one uncertain move may land you waist deep in the snow along the untamed slopes of fraught with numerous risks for the novice.

but. there you can see a large area covered with snow there were lots of trees there five years ago or so to go to a big avalanche in december swept away everything in its way. places a constant reminder of the threat posed by avalanches. free riders from neighboring towns have built cabins in the foothills of mount my mind they spend weekends here there is nothing inside apart from stoves tables and makeshift beds the cabins are almost buried in snow which makes them look like big

snow drifts with smoking chimneys before they get to the mountain top free riders spend a good deal of time scrambling along with skis on their backs or. yes you may not like it here you enjoy sliding down hill you're unlikely to enjoy going uphill on foot completely nor are you likely to be very keen to stoke the coals in the stove even during the night here you can't leave without wearing snowshoes to cope with it you really need to love it this landscape this forest this weather and this permanent snowfall.
