A repository of Earth models with the aim of providing the research community with access to various Earth models, visualization tools for model preview, facilities to extract model data/metadata and access to the contributed processing software and scripts.
The following products are in the i — Internal category (10):
Visualizations of real data showing how seismic waves sweep across the USArray network of seismic stations. Watch how seismic waves from earthquakes in the US and around the world cause the ground to move at each seismometer.
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.
Point-source synthetic seismograms are used along with vertical component recordings of short-arc Rayleigh waves (R1) from GCMT Mw7.0+ earthquakes to calculate source-time functions (STF) at GSN and other stations.
PDF/PSD Bulk Data Delivery System is an automated system that accepts BREQ_FAST-formatted requests and provides users with the requested PSD data files (daily bin files).
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.
