Multi-hazard events are causing severe impacts on our economy, society and environment. Moreover, the final damages are usually greater than the sum of single hazard impacts. However, the amount of data and observations covering multi-hazard conditions is still very limited. For this reason, the EO4MULTIHA project (https://eo4multihazards.gmv.com/), funded by the European Space Agency, aims at developing an open database gathering and harmonizing event information coming from already existing event databases to support multi-hazard(-risk) research. 

In particular, the database of the EO4MULTIHA project is a Relational Data Base Management System, based on open-source solution, that includes several novelties and features, such as 

(i) the link to existing event datasets through cross links and APIs to increase reusability with open standards (e.g. RESTfull APIs and OGC standards), 

(ii) the link to an extensive suite of data from satellite, climatological, in-situ, campaign and relevant statistics needed to describe hazard, exposure, vulnerability and impacts of multi-hazard events, 

(iii) the possibility to apply spatial and temporal filtering of events, 

(iv) the integration of Geostories focusing on specific multi-hazard events combining the available data and information into explanatory reports and 

(v) an initial focus on the 3 project study areas (the Adige River Basin in Italy, the southern part of the United Kingdom and the Dominica Island in the Carribean) with the possibility for future expansion to other areas, 

(vi) the development of a publicly available and open database with uploads coming from authorized contributors, 

(vii) standard metadata that describe datasets and allow their findability in international catalogues of the research community. 

The final product will be made available in a web portal facilitating the access of researchers, decision-makers and citizens to quantitative data supporting the understanding and analysis of complex multi-hazard events.
