EUROVOLC launched the EUROVOLC citizen science tool for volcanic events.
This is a platform for collating observations from people witnessing volcanic phenomena at European and other volcanoes. The tool allows you to contribute your own observations, as well as to access observations collected through other citizen science tools available across Europe, including myVolcano (British Geological Survey); sulphur dioxide reporting (Iceland Met Office); and Osservatorio Vesuviano web questionnaire & Tefranet (INGV-Catania). The EUROVOLC tool harvests the data from the other citizen science tools on a monthly basis.
Users are able to view and download the data and filter by, for example, date, geographical location, type of observation, or a specific citizen science tool.
