FDSN WS-EVENT raw demo access

We expose a HTTP web service conform to the FDSN WS-EVENT specification providing all our event data. Event information can include all origins and all arrivals as desired. Output format can be Quakeml, Json or Text. The full description of data and specifications of the webservice are in this document.

This web form will help you to learn and construct url with parameters to be used in a shell script for example (with curl or wget) or any programming language providing http client connection. Tutorials are available on EMSC github as Use cases (python/shell/notebook) and as Hands-on-Session (python). This service is integrated into the EPOS platform .

The FDSN server has recently been updated (2023-03) to a more modern framework and the maximim number of events per request has increased to 20000. There may be small disparities with the previous server that require adjustments to your requests, for instance around the formats of times, please contact us if there are problems with the new server. The old server will temporarily run at www.seismicportal.eu/fdsnws_old/event/1/query for a few weeks to ease the transition.

Some framework can automatically generate binding from WADL description file, so the link is here
