EventPlots Maps, record sections & other plots for M6.0+ events

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.

USArrayGMV The USArray Ground Motion Visualization

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.

BackProjection P-wave back-projection rupture imaging

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.

Infrasound TA Infrasound Data Products

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.

SWS-DB-MST The Missouri S&T western and central United States shear-wave splitting database

The shear-wave splitting measurements for western and central United States is a teleseismic shear-wave splitting (SWS) database based on all the data from all the broadband seismic stations in North America that contains over 16,000 pairs of well-defined (and manually checked) SWS measurements for the western and central United States (west of 90°W).

EARS EarthScope Automated Receiver Survey

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.

EQEnergy Earthquake energy & rupture duration

Earthquake energy and rupture durations are estimated following all earthquakes with initial magnitude above Mw 6.0 and a GCMT moment tensor. The method follows Convers and Newman, 2011. These are fully automated and not reviewed by a human.

ShakeMovieSynthetics 1D & 3D synthetic seismograms from the Global ShakeMovie project

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.

SourceTimeFunction Short-arc Rayleigh wave source-time functions

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.

MomentTensor Centroid Moment Tensors

Global Centroid-Moment-Tensors from the GCMT project at Lamont-Doherty Earth Observatory are available through SPUD within minutes after their publication. Initial quick-CMT solutions are shown and are later updated to GCMT solutions when updates arrive.

SeisSound The Audio/Video Seismic Waveform Visualization

The SeisSound Visualization is an audio/video-based IRIS DMS data product that illustrates the frequency and amplitude content of seismograms. Conveying the seismograms frequency content both visually and audibly produces a better understanding of their spectral content.
