Avalanche incidents

Dataset

Definition: The dataset provides an overview of recorded landslide events in Norway and is also known as the National Landslide Event Database (NSDB). The NSDB is managed by the Norwegian Water Resources and Energy Directorate (NVE) and contains over 100,000 recorded landslide events. The goal of the NSDB is to collect landslide records from various sources into a single national database. The Norwegian Public Roads Administration accounts for the majority of the landslide records in the database, but many landslides are also recorded by Bane NOR, NGI, NGU, NVE, and other individuals. In recent years, the number of records has increased significantly, but the database also includes many major historical landslide events, especially those related to fatal accidents. All landslide events registered via Varsom Regobs or Skredregistrering.no end up in the NSDB.

Usage

Knowledge of past landslide events is a very important foundation for assessing, forecasting, and mapping landslide hazards. Understanding landslides that have occurred throughout history contributes to a better understanding of the landslide risk in an area. When using the data, it is important to be aware that the information comes from various contributors and has been collected for different purposes. As a result, the records vary in level of detail and quality. Only selected landslide events undergo quality control. The Norwegian Water Resources and Energy Directorate accepts no liability for damage or injuries due to errors in data and incorrect use of data.
