The massif Little Man has moved between 35 and 40 centimeters since measurements were intensified last autumn. Avalanche experts expect up to 180,000 cubic, 18,000 truckloads, can come simultaneously down towards Romsdalen.
It is an upgrade of 60, 000 cubic compared to estimates last year, writes adressa.no.
NVE has registered increased movement recently. The movements in the mountains now implies that the danger level is set to moderate hazard (yellow), writes NVE in a statement Tuesday morning. Only in the last day has mountain party moved four millimeters.

– We must have some movement in the lower part of the mountain before we approach a landslide. We are now in a prepare else phase, says Blikra, which estimates that mountain party since October 6th and until today has moved between 35 and 40 centimeters in total.
– What do you think will happen in mountain if the weather forecasts for the coming days turn to high temperatures and no rain?
– We do not think it will accelerate quickly, but it comes much precipitation simultaneously with high temperatures a lot can happen quickly. We’re mountainous area carefully and will make it even more closely in the years to come, says Blikra, stressing that there are heavy snowfalls in mountainous area to let off steam, which is now melting.

In connection with higher temperatures and incipient melting snow movement has picked up in recent weeks.
The whole area which was moving in autumn 2014, are now active and moving. The speeds of movement is greatest in the upper part and is now at approximately 4 mm / day. The velocities in the lower part of the mountain is much smaller. The movements are much lower than those measured in October 2014. Then the rates at some point in nearly 70 mm / day.
The larger mountainous area man has slight movements and located on green fare levels without signs increased movement.
