Data Services Products
Data products derived from raw data are produced both by the scientific community and the EarthScope
DMC
. These complement the simple data products based on raw data such as event segmented waveforms, which are available via the
DMC
s traditional
data access
mechanisms. To ensure that the data products are useful to the research community, direct feedback and guidance is provided by the
Data Service Standing Committee
DSSC
).
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 EarthScope'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 EarthScope DS 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.
