ThinkHazard! is a new web-based tool enabling non-specialists to consider the impacts of disasters on new development projects. Users of ThinkHazard! can quickly and robustly assess the level of river flood, earthquake, drought, cyclone, coastal flood, tsunami, volcano, and landslide hazard within their project area to assist with project planning and design.

ThinkHazard! is a simple flagging system to highlight the hazards present in a project area. As such, a user is only required to enter their project location – national, provincial or district name. The results interface shows a user whether they require high, medium or low awareness of each hazard when planning their project.

ThinkHazard! also provides recommendations and guidance on how to reduce the risk from each hazard within the project area, and provides links to additional resources such as country risk assessments, best practice guidance, additional websites. ThinkHazard! also highlights how each hazard may change in the future as a result of climate change.

The ThinkHazard! methodology is documented here.

ThinkHazard! provides a general view of the hazards, for a given location, that should be considered in project design and implementation to promote disaster and climate resilience. The tool highlights the likelihood of different natural hazards affecting project areas (very low, low, medium and high), provides guidance on how to reduce the impact of these hazards, and where to find more information. The hazard levels provided are based on published hazard data, provided by a range of private, academic and public organizations.

Users and potential partners can contact ThinkHazard! administrators with queries or information to add to the tool, at the ThinkHazard! feedback form. This form is available on every page of the website.

The hazard levels and guidance given in ThinkHazard! do not replace the need for detailed natural hazard risk analysis and/or expert advice. While ThinkHazard! does its best to scientifically determine the hazard level, there are still uncertainties in the data and analysis. Users of the tool should access more information by contacting relevant national authorities, reviewing the recommended resources, and through accessing detailed hazard data.
