The Making Of Germany's Natural Hazards Portal - code, pipelines, and cloud services

Germany’s new natural hazards portal for the general public, “Naturgefahrenportal” (NGP) was released in April 2025. The NGP aims to consolidate various sources of hazard-related data onto a single accessible platform, promoting public understanding and preparedness. To this end, the NGP website presents current warnings for Germany, location-based hazards and risks as well as concrete measures for preparedness and behavior in a case of emergency.

The NGP serves as a central hub of information for the general public, aggregating the most relevant information in a uniform way, while linking to regional or single-hazard portals for further interest. It does not provide push notifications but complements existing public alert systems with a situational overview for Germany and background information on natural hazards.

This presentation will provide a technical overview of the NGP web app developed at the German National Meteorological Service Deutscher Wetterdienst (DWD) - from data sources and code to deployment pipelines and cloud services. The data sources for natural hazards information in Germany are distributed over several federal institutions at different administrative levels. The data has to be collected via APIs or received via SFTP, and the contents is prepared for display in a portal for the general public in a backend in python. Local repositories at DWD define Infrastructure as Code for the web app, which is deployed in a public cloud. The NUXT/Vue.js Frontend delivers the static website via a Content Delivery Network (CDN).

A brief section provides information on why a public cloud was chosen as platform and how the team work is organized.
