Notice This web service will not be offered long term. Users are recommended to transition their use of this service to other endpoints. Of particular interest for DMC users:

International Seismological Centre:


United States Geological Survey:

The fdsnws-event web service returns event (earthquake) information from the catalogs submitted to the IRIS DMC.

Events may be selected based on location, time, catalog, contributor and internal identifiers. By default, events are retrieved from the NEIC PDE catalog for recent events and then the ISC catalog when it becomes available. These default results include only that catalog’s “primary origin” and “primary magnitude” for each event, they may optionally include all available magnitude estimates.

By default results are returned as XML in QuakeML format (schema), but may also be requested in text formats.

This service is an implementation of the FDSN web service specification version 1.

Please remember that data obtained from our fdsn-event webservice should always be appropriately cited. More information about proper catalog citations can be found under the Event catalogs and citation section in the service Help page.
