The KNMI offers various services that provide access to Open Data from the KNMI seismic and acoustic networks and the products derived from it. Some of these services are offered directly by the KNMI, either via dedicated tools or via the KNMI Data Platform. Other services are offered by the ORFEUS Data Centre within the European Integrated Data Archive (EIDA) framework. In addition to the services advertised in this page, the KNMI website offers general public information (in Dutch) about last earthquakes, live seismograms, dossiers and research publications.
