Dear FDSN team,

I would like analyze some earthquakes that were detected in Europe back in 2013. I know Orfeus and some other European agencies have adapted FDSN standards, but not all of them provide web-based fdsnws-event services. For example Orfeus does not provide web-based fdsnws-events as far as I know. Some others (seismicportal.eu) do provide fdsnws-event capabilities... but I believe they don't have all the events that have been officially reported in European seismic stations.

Could you please advise on what would be the most comprehensive place (agency) to investigate events/earthquakes that take place in Europe?

Thanks
David

    Hello,

    You may want to consider the ANSS Comprehensive Catalog, which includes
    both NEIC and ISC-GEM catalogs:

    Thanks,

    Jeremy

      Hi David,

      Europe is a little complicated with so many individual seismic agencies, often multiple in a single country.

      The authoritative agency providing real-time earthquake information for Europe is EMSC, who collect parametric data from the various national agencies. They also until recently discontinued providing a manually reviewed bulletin - I don’t believe they offer a revised bulletin for 2013, but their realtime earthquake information is available using fdsn-event at:
      http://www.seismicportal.eu/fdsnws/event/1

      The reason the EMSC catalogue was discontinued is because the ISC catalogue practically replicates the EMSC effort for the European region. ISC also retrieve and homogenise the parametric information from individual agencies, down to a very low magnitude of completeness for Europe. The ISC catalogue can be queried using fdsn-event at
      http://isc-mirror.iris.washington.edu/fdsnws/event/1/

      Both the finally manual catalogue versions are significantly behind realtime.

      A (growing) handful individual agencies in Europe offer authoritative earthquake catalogues for their own regions - e.g. Italy, Switzerland. If you are interested in a particular country, you would be better served to retrieve data from the authoritative agency directly - see
      http://www.fdsn.org/webservices/datacenters/
      for an updated definitive list.

      The main advantage of the ISC / EMSC catalogues are a significantly reduced magnitude level for Europe, and locations constrained by nearby seismic stations. Depending on what is the minimum magnitude and location precision you are interested in, global catalogues may be sufficient for your purposes.

      The goal of ORFEUS is to make waveform data from Europe openly available, and this group does not provide an earthquake catalogue - for realtime event purposes, when required, ORFEUS uses EMSC event information.

      regards,

      John
