Hazards and risk in Medellín
Explore 716 flood-hazard and 2,376 landslide-hazard polygons using the four degrees in the official land-use-plan legend: very low, low, medium and high. The torrent-flow layer adds 115 polygons with its own three-degree blue legend. Three Municipal Disaster Risk Management Plan layers add 507 scenario polygons: 63 mass-gathering, 409 wildfire and 35 technological-hazard records, each with its published magnitude vocabulary. Also inspect areas with risk conditions and non-mitigable high risk in their separate layer. Review categories, dates and geometry while distinguishing hazard, risk and recorded events.
The hazard layer refers to the land-use plan adopted under Agreement 48 of 2014. Flood and landslide records state an April 30, 2026 update; torrent-flow records include April and July 2026 dates; metadata retains a 2016 revision and an earlier count. Risk conditions reference June 18, 2021. The 507 risk-management plan scenarios publish no dates or reuse license. These are different sources and dates. They are not warnings, events, property assessments or a complete hazard inventory. Consult Planning and the official adopted map for authoritative decisions.

How to use itHow to use the map
- Open the viewer with this theme’s first layer enabled. Search a neighborhood or enter coordinates as latitude, longitude.
- Enable other layers in the theme and zoom in. Detailed cadastral layers require a close scale to keep queries bounded.
- Select a feature on the map or in the Results list. Check its attributes, retrieval time and any partial-result notice.
- Choose a field and exact value to filter the layer. Export includes only received results, with attribution and dates; it does not download the whole municipality.
Sources, dates and limits
Each source’s verification date appears in the table. Retrieval time is not the data update date. Small city-wide layers use the full extent; larger layers depend on the visible area. Reference publications retain their original retrieval date. Each response contains up to 500 features and 2 MB. Reference publications load matching pages, up to 5,000 features and 8 MB per query. External services may return partial samples, identified in the viewer.
