The CAPRA Platform aims to strengthen institutional capacity for disaster risk assessment and communication and has been managed and owned by Uniandes (Universidad de los Andes) since 2017. It provides a series of tools for hazard (single and multiple unrelated), exposure and vulnerability assessment that can be used standalone, or integrated in the probabilistic risk assessment software: CAPRA-GIS.

The hazard module includes software applications for geological (earthquake, tsunami, volcano), hydrogeological (drought, flood, hurricane) and climate change hazard assessment.

The exposure module consists of a data entry software for collection of information about infrastructure potentially exposed to a hazard.

Vulnerability modules enable users to develop vulnerability curves for each hazard class and asset, which are required for the probabilistic risk assessment.

CAPRA-GIS v2.4 is the latest version of the probabilistic risk assessment software. It is a Geographic Information System intended for probabilistic risk calculations. Outputs from the hazard, exposure and vulnerability modules are in the correct format for importing into CAPRA-GIS for the risk assessment. It is freely available to download from along with a user manual (in English).

Technical considerations

All tools are freely available to download from the CAPRA website and can be run on Microsoft Windows. Input data files for probabilistic risk assessment using CAPRA-GIS are generated from the hazard, exposure and vulnerability modules. User manuals are available online.
