One phenomenon generated NOK 1.5 billion in losses. Three out of four municipalities face nature

The latest data shows that three out of four municipalities in Norway have been affected by dangerous natural phenomena over the past two years. The data was also presented by Naturfareforum. The financial impact is counted in billions of NOK.

In 2025, compensation costs for damage to buildings and property amounted to NOK 3 billion. The data comes from Naturskadepoolen. Half of this amount resulted from the extreme weather event "Amy." Losses from this phenomenon were estimated at NOK 1.5 billion.

The list of incidents is longer. The Dovrebanen railway line was closed after ice jams formed on the Ottaelva river. Residents were evacuated following a rockslide from Oksfjellet. Heavy rainfall led to flooding in Sokndal, where losses were estimated at NOK 11.4 million.

A significant portion of the damage is related to storms and strong winds. The damage affects railways and roads, as well as residential buildings. Both insurance payouts and funds from the state compensation system are high.

The effects also include forests, as well as power and telecommunications networks. There are interruptions in electricity supply and communications. Such events occur throughout the year and include snow, avalanches, floods, landslides, droughts, and fires. According to NVE, municipalities are better prepared today than 10–15 years ago, but the scale of threats is increasing.

Between 2011 and 2023, nearly NOK 20 billion was spent on repairing damage from extreme events. Less than NOK 5 billion was allocated to preventive measures. The data shows a difference in spending structure. The concentration of CO2 in the atmosphere has reached 428.6 ppm, and the temperature increase compared to pre-industrial levels is +1.19°C. According to climate data, Norway may lose 32 days of winter over the next 75 years.
