Rockfall - rough susceptibility zones

Susceptibility areas for rockfall is a national series of maps showing areas that are potentially vulnerable to rockfalls at a general level. The maps show potential source areas and run-out areas for rockfalls.\\nYour attention is drawn to the fact that the areas covered by source areas are in practice run-out areas as well, as avalanches that are triggered right at the top of the source area move through trigger areas below, before reaching the run-out areas at the bottom. Therefore, both source areas and run-out areas should generally be used together when using the dataset for analysis purposes. \\nThe susceptibility areas are identified by means of a data model which uses the slope of the terrain and geological information to recognise potential source areas for rockfalls. The run-out area for rockfalls is calculated automatically from each source area. No fieldwork is done when identifying or defining the areas.

Purpose

First and foremost, the susceptibility areas are intended as a basis for assessment of the risk of landslides in spatial plans at municipal planning level. The areas indicate nothing about the likelihood of rockfalls. The Norwegian Water Resources and Energy Directorate's guidelines "Flaum- og skredfare i arealplanar" describe the use of the susceptibility maps and other maps indicating landslide risks for spatial planning.\\n\\nThe limitations of the terrain model on which the maps are based mean that steep slopes of less than 20 m that are potentially hazardous in terms of landslides are not identified or defined on the maps. In some instances, steep slopes of between 20 and 50 m may also not be included. Smaller steep slopes of this kind therefore have to be assessed separately in connection with planning and development. If information is available on previous landslide events outside susceptibility areas, these areas should also be included in the assessment.

Supplemental Information

The dataset Rockfall susceptibility areas comprises the polygon themes **UtlosningOmr**(sorce area) and **UtlopOmr**(run-out area). **UtlosningOmr** covers areas where rockfalls may potentially be triggered, while **UtlopOmr** similarly covers the potential run-out areas for these source areas.\\n\\nSusceptibility areas for rockfalls provide a basic overview of areas that are potentially vulnerable to rockfalls. A national elevation model (Norwegian Mapping Authority) with a resolution of 25x25 metres is used, where the basic data is based mainly on 20 m contour lines. This is equivalent to what is found in a standard topographical map in mapscale 1:50 000.\\n\\nThe dataset is adapted for use together with N50 (1:50,000) background data, and the accuracy of the dataset indicates that it should not be used together with background data which involves a higher level of detail than this.
