Data Services Products: EventBulletins Event Bulletins


The DMC archives phase arrivals from the USArray Array Network Facility in addition to other DMS sources. The event bullentins are added to the DMC’s event tables, making them available via the standard event query interfaces. The original submissions are also available as products.


Within the IRIS Data Management System some data collection and processing nodes perform picking of phase arrivals on seismograms as part of a their processing. These phase picks are usually associated with origin estimates from the ISC, USGS NEIC or regional network operators.

These data have also been added to the IRIS DMC’s event tables and will eventually be available from other interfaces such as SeismiQuery and the DMC’s ws-event web service.

These products are presented here in the same format in which they were submitted to the DMC. Usually this is the IASPEI Seismic Format (ISF) with DMC extensions, for more information on this format please see ISF format with DMC extensions.
