Description
The Autonomous Province of Trento , in accordance with Article 10 of Provincial Law No. 9 of 1 July 2011, ‘Regulation of civil protection activities in the Province of Trento’, has drawn up hazard maps for its territory.
The Hazard Maps (CaP) take into account hazards associated with hydrogeological phenomena, avalanches, floods, earthquakes, forest fires, certain hazardous substances, overhead cables or other obstacles to air navigation, and unexploded ordnance.
These are a series of tools resulting from forecasting carried out by the Civil Protection Department (Article 1 of Provincial Law 9/2011), which involves the identification, delineation and classification of the hazards and risks present within the territory.
The CaP classify the provincial territory according to the following types of hazard:
| HYDROGEOLOGICAL HAZARD River hazards Torrent hazards Lake-related hazards Landslides Rockfalls Deep gravitational slope deformations (DGPV) Avalanches Glaciers and the Little Ice Age (LIA) Permafrost and rock glaciers Litho-geomorphological characteristics | OTHER HAZARDS Seismic hazard Forest fires Unexploded ordnance Hazardous substances Overhead cables and obstacles to air navigation |
|---|
The hazard classes are defined on the basis of the reference document “Criteria and methodology for the preparation and updating of hazard maps”, approved by the Provincial Executive in its latest version by Resolution No. 1306 of 4 September 2020.
To ensure consistency in representation, this document stipulates that expected events are categorised according to the same hazard classes, differentiated on the basis of foreseeable effects, without prejudice to the possibility that ad hoc measures may be adopted for specific phenomena or geographical contexts.
The provincial bodies responsible for drawing up the maps and carrying out the activities are the Geological Service, the Risk Prevention and CUE Service, the Fire and Civil Protection Service, the Mountain catchment areas Service and the Forestry Service.
The CaP represent the basic tools for prevention activities (activities aimed at eliminating or reducing risks, both through prescriptive and binding measures for the proper use of the land and through structural interventions) and protection (activities, predominantly of a planning, organisational, cultural and training nature, and management measures aimed at mitigating the harmful effects arising from risks that cannot be eliminated through preventative measures) within the civil protection framework.
From this perspective, the CaP form the reference framework for the development of two key land-use management tools: the General Risk Map provided for by Provincial Law 9/2011 and the Hazard Summary Map (CSP) provided for under Article 22 of the Provincial Law on Land Management(Provincial Law No. 15 of 2015).
The regulations governing these tools stipulate that they must be subject to periodic updates in response to requests submitted by local authorities, organisations, private individuals and provincial administrative bodies, following in-depth analyses, studies and new hydrogeological phenomena that may have occurred in the meantime.
The Provincial Executive, by Resolutions Nos. 1341and1361of 12 September 2025, approved the second update of the Hazard Maps and the Summary Hazard Map for the entire provincial territory, which came into force on 19 September 2025, the day following their publication in the B.U.R.. On 18 September 2026, the Provincial Executive, by Resolutions Nos. 1422 and 1447, amended the previous resolutions, due to a mere clerical error concerning avalanche risk relating solely to the Pampeago area in the municipality of Tesero.
The cartographic content of the approved CaP is available online to anyone via a web GIS, allowing users to view the maps by theme and todownload the shapefiles and multi-layer PDFs at a scale of 1:10,000.
NB: Please note that the correct interactive display of the maps in the multi-layer PDFs also depends on the browser used. Should they fail to display correctly, you will need to download the file to your computer and open it using ADOBE READER.
The maps are also available online via the following links:
The Hazard Maps (CaP) relating to Unexploded Ordnance, Hazardous Substances, Overhead Cables and Obstacles to Air Navigation are not currently available in the integrated viewer mentioned above, but only as PDF files, as they have been produced on a smaller scale:
- PDF Map of Unexploded Ordnance Hazards
- PDF Hazard Map: Obstacles to Air Navigation
- PDF Hazard Map for Hazardous Substances

NB: Maps for each topographical section at a scale of 1:10,000 are available for download in SHP and PDF formats can be carried out using Webis AGOL.
