Back in 2009, the directorate was given the responsibility of initiating also a national forecasting service for rainfall- induced landslides. Both services are part of a political effort to improve flood and landslide risk prevention. The Landslide Forecasting and Warning Service was officially launched in 2013 and is developed as a joint initiative across public agencies between NVE, the Norwegian Meteorological Institute (MET), the Norwegian Public Road Administration (NPRA) and the 15 Norwegian Rail Administration (Bane NOR). The main goal of the service is to reduce economic and human losses caused by landslides. The service performs a national landslide hazard assessment every day describing the expected awareness level at a regional level (i.e. for a county and/or group of municipalities). The service is operative seven days a week throughout the year. Assessments and updates are published at the warning portal www.varsom.no at least twice a day, for the three coming days.
