The hillside that collapsed on Sunday evening had been identified as high-risk years earlier. A 2009 engineering report warned the slope was dangerous. This occurred when student housing organization SiO sought construction permits from Oslo municipality.
A geologist renewed landslide warnings in 2021. SiO claims they cleared loose rocks and conducted annual inspections. Their last visual inspection happened this year.
SiO states they haven't seen need for special cleanup of loose masses since 2022. The organization maintains regular safety checks despite the known risk.
This incident raises questions about whether routine inspections sufficiently address long-identified geological hazards. The gap between professional warnings and actual preventive measures appears concerning for residents' safety.
