Data products derived from raw data are produced both by the scientific community and the IRIS DMC. These complement the simple data products based on raw data such as event segmented waveforms, which are available via the DMCs traditional data access mechanisms. Community guidance is for our product development efforts is provided by the Data Products Working Group; feedback, suggestions and input are welcome at any time.
Below is a list of products produced either at the DMC or by the research community that are available from the DMC. Many of these products are available in SPUD where you can easily search for and download products.

The IRIS DMC's Event Plot product is a suite of plots that are automatically generated following all earthquakes of magnitude 6 or greater. The plot suite uses all open broadband data, or a sub-selection, available at the IRIS DMC at the time the product was generated. Based on data availability and signal quality, some plots may not be produced for certain events.
The Back Projection (BP) product shows the beamformed time history and location of coherent short period P-wave energy generated by large earthquakes observed at three regional arrays and across the Global Seismic Network. These are generated following all global M6.5+ earthquakes. The back projections typically take less than 10 minutes to compute, however arrival of event triggers, travel time of P-waves, downloading of data and shared DMC computing resources delays publication of results in SPUD to about an hour after origin time. These are fully automated and not reviewed by a human.
To support USArray TA infrasound data set, the IRIS Data Management Center (DMC) has developed two infrasound data products: the TA Infrasound Reference Event Database (TAIRED ) and TA Infrasound Detections (TAID ). These two data products are designed to provide insight and tools for researchers to begin working with this large, and somewhat unique, new data set.
The SplitLab Shear-Wave Splitting Database is a mirror of the Géosciences Montpellier's SplitLab Shear-wave splitting database that provides access to this valuable database using the SPUD system and its customized Google Maps interface.
The EarthScope Automated Receiver Survey (EARS) calculates bulk crustal properties of IRIS stations using receiver functions. Originally developed at the University of South Carolina, EARS continuously monitors for new events and stations updating the database when new candidate data are found.
Download synthetics from ShakeMovie website
The Global ShakeMovie website at Princeton provides bundles of all calculated synthetics in SAC format for reach event as tar files.
Search for synthetics at IRIS
Events for which synthetics are available in the DMC archive are listed in SPUD.
USArray magnetotelluric transfer functions calculated from USArray MT stations by Oregon State University are available from the SPUD EMTF repository in both XML and EDI format and also directly from the DMC’s website in the EDI format.
An XML format for electromagnetic transfer functions and related conversion software was developed by OSU with funding from IRIS. The software and documentation is available in the SeisCode EMTF-FCU project.
EMERALD is a complete open-source software server-based system for requesting and processing large sets of event based seismic data from a web browser. Data sets containing millions of seismic waveforms can easily be managed, reviewed, and processed. The system can automatically check for metadata updates, and alert the user to metadata changes.
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.
The EarthScope website contains a list of data products derived from EarthScope data.
