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.

USArrayGMV-Super IRIS DS Super (Combined) GMVs

The Super or Combined GMVs are created using multiple events from the same source area with 1 to 1.5 years time spacing. Such time spacing allows more complete coverage by The USArray Transportable Array (TA) stations as it rolls eastward.

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.

TA infrasound detections are produced by regularly scanning the USArray Transportable Array broadband infrasound data (40 Hz BDF channel) and generating weekly detection lists.

EMC-DNA09 Finite-frequency P- and S-velocity models for the western United States

DNA09, Obrebski, Allen, Xue & Hung (2010) , model is obtained through the body wave finite frequency tomographic inversion of the available EarthScope-USArray data recorded from January 2006 to July 2009.

EMC-DNA10-S S-velocity model for the western US integrating body- and surface-wave constraints

DNA10-S model, Obrebski, Allen, Pollitz & Hung (2011), integrates teleseismic body-wave traveltime and surface-wave phase velocity measurements into a single inversion to constrain the S-wave velocity structure beneath the western US.

HVSR Horizontal:Vertical Spectral Ratio (HVSR)


Status: Under development
Last update: 2015-09-10

The horizontal to vertical spectral ratio (HVSR) of a station’s ambient noise provides useful information on its site response characteristics. The proposed product allows HVSR computations using available power spectral density (PSD) data and creates a site response database for the TA stations in Alaska.
