SPUD Version 3.0

The Searchable Product Depository (SPUD) is the IRIS DMC's primary data product management system. Complementing the DMC's SEED and assembled data archives, which contain time series recordings, the SPUD system primarily contains derivative data products of other types (images, movies, etc.) created either at the DMC or by members of the community.

For users SPUD is the query and access point for these products. The web interfaces allow users to search for products using customized queries across product and event details. Users can search across all product types at once or within specific product types. SPUD also has web service interfaces for programmatic discovery and access to the data products.

If any products from SPUD are used in your research please be sure to cite the identified author of the product and the IRIS DMS [Citation Information].

Earthquake energy and rupture duration are estimated by integrating P-wave energy from a global distribution of stations from 25-80 degrees distance following all Mw 6.0+ earthquakes with a GCMT moment tensor. The method follows Convers & Newman, 2011. For more information regarding EQ Energy products visit the IRIS EQ Energy Product Page.
