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 Surface-Wave Radiation Patterns Products

The Surface-Wave Radiation Pattern product shows the patterns of seismic energy radiation by azimuth around the epicenter for Rayleigh and Love waves. The spectral amplitudes for Green’s functions obtained for elementary moment tensors observed at virtual stations are obtained from Mineos, an open-source software that computes synthetic seismograms in a spherically symmetric non-rotating Earth by summing normal modes. By convolving the spectral amplitudes with the components of the moment tensor as given by the Global CMT Project, the radiation pattern for different source mechanisms is obtained.

For more information on surface-wave radiation patterns visit the product page.
