Is the property in a hazard awareness zone?
Rated risk of flooding, landslide, quick clay and radon on a property, with level, source and free-text note for each risk type, in one call.

From property to natural hazard
The call tells you whether a property lies in a hazard awareness zone for natural hazards, and how certain the rating is. Banks use it in credit assessment before a mortgage, insurers use it to price natural damage risk, and developers use it for early screening of plots before ordering a geotechnical survey for the plots that actually need one.
Each of the four risk types, flooding, landslide, quick clay and radon, gets its own level, a source and a free-text note from the source's own register. NVE is behind the rating for flooding, landslide and quick clay; Direktoratet for strålevern og atomsikkerhet (DSA, the Norwegian Radiation and Nuclear Safety Authority) is behind the radon rating. The levels are not comparable across risk types: a MEDIUM rating for quick clay and a MEDIUM rating for radon rest on completely different methods and different thresholds, set by two separate agencies.
⚠️ A level of UNKNOWN means the register does not cover the property yet, not that it has been rated free of risk. Do not use absence of data as documentation of low risk.
The levels are hazard awareness ratings, not hazard zone maps for a single property: they point to a need for closer investigation, not a final answer on whether the property is safe to build on. A property with a low level today can get a different level after a new mapping round, without anything having changed physically on the plot. See Map layer: Risk for the underlying hazard awareness maps, and flood zone for how return periods are read.
Level, source and note per risk type
Flooding, landslide, quick clay and radon each get their own level, source and free-text note from the source's own register, instead of four separate lookups.Hazard awareness, not hazard zone maps
The levels point to a need for closer investigation, not a final answer on whether the property is safe to build on.UNKNOWN is not low risk
A level of UNKNOWN means the register does not cover the property yet, not that it has been rated free of risk.
Fields that actually tell you something
One GET call on the property gives you all four risk types.

The levels are not comparable across risk types: each agency sets its own method and threshold.

Data and sources
The flooding, landslide and quick clay ratings come from NVE, updated continuously. The radon rating comes from Direktoratet for strålevern og atomsikkerhet (DSA).
