About SPUD

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].

About Moment Tensor Products

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. The download button gives users the full NDK format solution. For more info, visit: www.globalcmt.org.
