The specially trained so-called Nusar team entered the risk zone on Thursday together with Norwegian dog patrols to search “one or two houses.”
– We are in the process of looking for the landslides in the lower area, said Task Manager Roy Alkvist in the Norwegian police at a press conference over lunch.
A few hours later, Alkvist announced that a body had been found. The police have not yet come out with gender or age because the relatives have not been notified.
– We will work tirelessly on the search, he says.
Temporary bridge
The floor of the avalanche crater is very wet in some places and more solid in others. The effort is made on relatively stable ground.
At the site of the avalanche zone there is a paver, a military vehicle that can temporarily bridge. But the vehicle is considered to be too heavy for the area in question.
Instead, the rescue team has used Styrofoam tiles that they lay on top of the clay to get around in the safest way possible.
The operation, which began at 11:30 a.m., has been planned overnight through new investigations with drones and helicopters.
Still at risk of landslides
Society must remain prepared to be able to evacuate more areas, says task leader Toril Hofshagen of the Norwegian Water and Power Authority. Drilling and other investigations are carried out all the time in both evacuated and still inhabited areas. During New Year’s Eve, new landslides occurred in the great pit, which measures about 700 times 400 meters.
A nursing home needed to be evacuated. Fortunately, it was possible to find empty hospital rooms near Oslo, and our own staff were able to track it. The fact that some are infected by corona could also be handled, rescue management said at an earlier press conference.
– We have chosen an area where survivors are most likely to be found, operations manager Ketil Lund told VG.
On New Year’s Eve, another dog was rescued. The dog was discovered with the help of a drone’s thermal camera and was lifted to safety by helicopter.
During the night of the end of the year, a Dalmatian was rescued.
– We realize that it will be people who have died, but rescue personnel believe that we can still find someone alive. And that’s what we expect, says Karianne Knudsen in the police.
Warned for construction
Hydrologist Steinar Myrabø says he warned the municipality in 2008 when the area would begin construction. Then he was chief engineer at Jernbaneverket.
It was then a watercourse that was flooded and caused erosion. Myrabø later said, according to Eidsvoll Ullensaker Blad, that it was due to expansions in the vicinity and said the municipality needed to halt construction and review surface water management.
– No one knows what caused the landslide this week, but I know that the municipality did not follow the warning then, says Steinar Myrabø.
The area where the landslide occurred was classified as a high-risk area, a five on a five-point scale, when the municipality gave the green light for expansion in 2005.
The Norwegian Geotechnical Institute NGI requires careful soil investigations in such cases, and builder Odd Sæther tells NRK that they have followed NGI’s guidelines.
– Once the emergency phase is over, it is relevant to evaluate the reasons why this happened. So it is natural to think that erosion in the stream is one of the things to assess, says NGI engineer Guro Grøneng on Norwegian radio.

The alarm for the landslide reached the police at 3:59 p.m. on Wednesday, December 30.
At least 14 addresses in a residential area were affected by the landslide, which is located in Ask in the Gjerdrum municipality, south of Oslo’s Gardermoen Airport.
One person died in the avalanche.
Ten people have been reported injured, one of them seriously.
Nine people are still missing on Friday.
About 1,000 people have been evacuated from the area.
Helicopters are involved in search work and use, for example, heat search technology, and attempts have been made to locate lost mobile phones.
The Armed Forces, the National Guard, the Civil Defense and voluntary organizations participate in the work. The Greater Gothenburg Rescue Service has sent nine people there.
Several buildings with more than 30 houses have collapsed, as well as several garages.
