The next day, on the second day after a major landslide destroyed houses in a village near the Norwegian capital Oslo, rescuers were using helicopters, drones and dogs to scan the unstable ground. Local officials said at least 10 people are still missing and 10 others were injured.
On Wednesday, in Ask in the city of Gjerdrum, 15 miles northeast of the capital, the entire hillside collapsed overnight. Reuters reported that the house was crushed and buried in dense dark clay. It was still too unstable on Thursday for rescuers to enter on foot.
Lower temperatures than icing and snow made people work hard to support the remaining structures, finding that the lost houses were more challenging, some of them crumbling on the edge of the crater formed by a slide. Several buildings collapsed on Wednesday.
Norwegian Prime Minister Erna Solberg went to a village with about 1,000 people on Wednesday and called the landslide one of the largest in the country’s history.
Solberg told reporters: “It’s really an exciting experience to be here.”
She added: “The muddy situation is still so unstable that nothing can be done except helicopter rescue.”
Norwegian media said 700 people have been evacuated from their homes, and the city warned that as many as 1,500 people may need to leave the area for safety reasons.
Reuters quoted the head of police operations at the scene, Roger Pettersen, as saying: “We are still looking for survivors.” He added that there are still children and adults missing.
Police said ten people were injured. One of them was transferred to Oslo and was seriously injured.
Paterson said Wednesday that people said their entire house was inside and they made emergency calls. Overnight, the helicopter used thermal scanning technology to search for people and lowered several rescuers to the building as part of their efforts.
Paterson said: “There are a lot of reports and the situation is serious.”
According to the Norwegian Water and Energy Agency (NVE), a so-called “rapid clay landslide” of approximately 328 to 766 yards occurred.
NVE spokesperson Laila Hoivik (Laila Hoivik) told AFP: “Considering the number of houses involved and the number of evacuated people, this is the biggest landslide in Norway recently.”
Quick clay is a type of clay found in Norway and Sweden that collapses and becomes fluid when subjected to excessive pressure.
Hoywick said: “The area has been investigated and it is known to contain fast clay. At present, the possibility of similar large-scale landslides in the area is very small.”
Reuters quoted the Norwegian broadcaster TV2 as saying that a 2005 geological survey found clay and believed that the area was not suitable for residential development, but only two years later, new houses were built on the land.
The Norwegian King Harald said in a rare public statement that the accident “left a deep impression on him.”
He said: “My idea is to be with all the people who are affected, those who are injured, those who have lost their homes, and those who are now living in fear and uncertainty about the entire disaster.”
