The NVE may have found the cause of the avalanche

TROMSØ (Dagbladet): In the course of a very short window of time where the weather allowed a helicopter could fly up to the skredområdet in if we in Troms, checked skredeksperter from the NVE three different places around the roughly 300 metres wide skredsonen to do a safety assessment and to try and find the cause of the tragedy at Blåbærfjellet.

The missing is a Swedish woman and three Finnish men who were on the trip to the summit to Blåbærfjellet. The four were last seen around at 14 on Wednesday.

TO SEE the SNOW OUT IN the SKREDOMRÅDET: Here is the rhyme. It is what is the weak layer and which can propagate a fracture over large areas. The snow has been sliding out when it was charged in a test. It is the snow that has slipped out, which constitute the very floe in the avalanche. Photo: Markus Landrø/NVE. Show more

We have examined down by the skredtunga, where snømassene stopped, by the side of the avalanche on a ryggformasjon in height with løsneområdet where it was safe to examine the snow, " says Markus Landrø, which is skredekspert by the NVE.

- We have found it the same at all the places. Overflaterim. When overflaterim covered by the new snow, it creates a fragile construction that may collapse, " says Landrø to the Newspaper.

Overflaterim is formed when it is cold and the weather is clear.

the Assessment of the experts from NVE is that the conditions are now so unstable that søkemannskaper must be flown in by helicopter to skredområdet and that it can only be sought where the avalanche has passed and in areas where it is not steep enough to allow the new avalanche may loosen or be reached by the new avalanche.

Bad weather

But to fly søkemannskap into the unstable, steep skredområdet, need the weather to play on the team. And it did not on Friday night.

DESCRIPTION: - A snøprofil is a graphical representation used to describe the snow cover. The longer the beams are, the harder is the snow. The critical layer is located 90 cm. One can see that it is thin and very loose in relation to the snow below and above. It is probably in this made avalanche loosened, " says Markus Landrø. Illustration: NVE Show more

today there was a small weather window. We got up a helicopter now in the afternoon, but it was not to put down the machine. The weather changes very quickly, " says Viktor Olsen, who is aksjonsleder for the Red Cross local.

the Organization has been in place with crews from Skredgruppen in the county of Troms Red Cross Local, and have been ready until the rescue operation ended on Friday evening.

the Weather has been unstable with a lot of snowstorms and has prevented access to the to do search in skredområdet. Viktor Olsen says that the rescuers do not go into the area before the NVE and the Police have declared it safe.

- It is frustrating to feel that they don't get done what personnel we want in this situation with the background of the prevailing conditions, but the safety priorities are always first. The chance of finding survivors becomes less for every minute that passes, but one never gives up hope, says the experienced aksjonslederen.

He says that the team of volunteers has been focused on to carry out the mission, despite the fact that the action is called off for the evening.

Mental preparation

- To prepare mentally for the task. We think through the situation and what we may encounter, " says Viktor Olsen to the Newspaper.

Olsen states that it is not advisable to take into skredstedet with the snowmobile.

- It is very steep and exposed for snøskredfare on the way in, " says Viktor Olsen.

the Newspaper know that it was stated on a beredskapsmøte that the campaign has entered a new phase where we are no longer looking for survivors, but the search for casualties. When raised also the threshold for which risk redningsmannskap to take.

Is probably not the new search in the weekend
