Thread: Event webservice (version 1.1.0) release

Hello webservice users,

The DMC is pleased to announce the release of the ws-event webservice (version 1.1.0).

http://www.iris.edu/ws/event/

The event web service returns event information in the QuakeML format (schema 1.2 RC3). As with most of our other webservices, ws-event accepts simple HTTP GET query parameters. Events may be selected based on location, time, catalog, contributor and internal identifiers.

The IRIS DMC receives earthquake location and magnitude information primarily from the USGS NEIC and the ISC, other sources include the Global CMT project and the USArray ANF.

The FetchEvent Perl script available at http://www.iris.edu/ws/wsclients/ can be used to fetch event information from ws-event, parse the returned results and print the information as simple ASCII.
