Volcanological data are heterogeneous in nature. They come from field observations, ground based and remote sensing instruments, permanent stations or campaign deployments, and include geochemical analyses, geophysical time series, images, video, and other data types. These data are collected, processed,and stored in different formats, with varying levels of support and infrastructure, and are managed by diverse institutions worldwide (observatories, universities, and research institutions). Considering this framework, volcanologists have adopted different approaches and solutions to manage their data. The range of data management solutions reflects the goals with which the data are collected, e.g. scientific monitoring, hazard mitigation/civil protection, research projects. Technological evolution has added additional complexity to data management. During recent decades, data acquisition has dramatically increased in both quantity and quality, and previously analog data are now routinely acquired digitally.The recent implementation of the “Open Science” framework poses both technical and policy challenges to increasing data access within the volcanological community. This session solicits contributions on strategies and best practices being used and adopted by the volcanological community in managing and distributing data. We will discuss broad topics related to the application of the FAIR (Findability, Accessibility, Interoperability, and Reusability) principle to volcanological data,such as standardization of data and interoperability, data archiving/repository infrastructures, data access policies, data licensing, citation and publications.We also aim to stimulate a debate about the capacity of the volcanological community to guarantee a long-term curation of data for science reproducibility.
