The investigators in the Gjerdrum committee have concluded that the lack of securing of Tistilbekken is the main cause of the landslide, according to the newspaper Romerikes Blad.
The report of the landslide investigators was presented at a press conference in Gjerdrum at noon on Wednesday, but it was first presented to the relatives of the victims at Gjerdrum junior high school on Wednesday morning.
According to the newspaper, the investigators also pointed to poor protection over time, that the stream should never have been paved, that old pipes had leaked, and that this would have led to a lot of erosion in the quick clay area.
The Gjerdrum committee has been tasked with finding the causes of the quick clay landslide in Gjerdrum and assessing measures to strengthen the prevention of quick clay landslides throughout the country.
Østensen: Important for residents
The Ministry of Petroleum and Energy told NTB that the residents in the area have had a meeting with Minister of Petroleum and Energy Tina Bru (H) and committee leader Inge Ryan ahead of the press conference and that they have been informed of the conclusion in the report.
Gjerdrum Mayor Anders Østensen (AP) told Romerikes Blad that it is clear that the report is important for the residents.
“It’s a serious occasion. They are the ones who have been hit the hardest. We all sympathize with them and are happy that the answers that come are quite unambiguous,” Østensen told the newspaper.
