Quick Clay – Caution, already linked to every property.
Shows areas that may be exposed to quick clay landslides, based on marine clay deposits and terrain criteria (slope and height difference). If the measure lies within the caution area, the procedure in NVE guideline 1/2019 must be followed and geotechnical expertise obtained.
What the dataset contains
Quick Clay – Caution in Placepoint
Shows areas that may be exposed to quick clay landslides, based on marine clay deposits and terrain criteria (slope and height difference). If the measure lies within the caution area, the procedure in NVE guideline 1/2019 must be followed and geotechnical expertise obtained. The map replaces the earlier "Aktsomhet marin leire" and now also captures terrain that can trigger landslides. The map is updated regularly and should be seen together with the hazard zone map for a full assessment. Source: Norges vassdrags- og energidirektorat (NVE). Included in the Risk map layers in Placepoint.

NVE's flood awareness map: a coarser first assessment of where flood hazard should be investigated further.
About the datasetFire Stations Response Time
Placepoint's derived analysis of all fire stations in Norway with their driving response time zones: 5, 10 and 20 minutes, calculated from each station.
About the datasetFlood hazard map
The Flood hazard map shows areas that flood at different flood sizes (return periods).
About the datasetHigh tide / storm surge
Modelled storm surge and sea level rise zones for Norway's coast, supplied to Placepoint by Geodata AS.
About the datasetQuick clay
Quick clay is a particular type of marine clay that loses all its bearing capacity when disturbed or loaded. It is the single factor in Norwegian geotechnics that most often stops development projects or makes them more expensive.
About the datasetRadon susceptibility
Areas in Norway that are likely to be more exposed to radon than others, based on the Norwegian Radiation Protection Authority's (NRPA) national database of indoor air measurements and NGU's bedrock and superficial deposit databases.
About the datasetHow often is Quick Clay – Caution updated?
When the source changes. The frequency follows the source and is shown on the dataset in Placepoint.
Where does the data come from?
From Norges vassdrags- og energidirektorat. We collect and quality-check the data, then link it to the right property, with source and date on every field.
How do I see Quick Clay – Caution on a property?
Look up the address in Fusion and turn on the Risk map layer. The dataset is there as its own layer, and the details appear in the property panel when you click on the map.
Can I get the dataset programmatically?
Yes. The same data is available in Placepoint API and in Placepoint AI through MCP, so you can bring it into your own systems and agents.
