On August 30, a landslide occurred during construction work related to a new railway crossing at Nesvatnet. As stated in a press release by Bane Nor, the earthquake was triggered by ground reinforcement work involving a method known as lime cement stabilization. Senior geotechnical advisor Stian Baardsgaard Hanssen mentioned that the stabilization efforts created pressure on a permeable layer of the ground, leading to a significant weakening of the soil beyond what was anticipated.

Hanssen pointed out that the presence of quick clay in the soil contributed to the landslide's extensive impact, affecting an area much larger than the immediate work site. Tragically, an employee of Bane Nor's contractor lost their life in the incident, and the landslide also impacted major roads, including both new and old E6, as well as the railway infrastructure.

This incident raises concerns about the safety protocols in place during such construction activities and the potential risks associated with ground stability in areas with quick clay. Following this incident, Bane Nor is suspected of negligence in their operations, prompting further investigation into the events that led to this devastating event.
