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.

Citing Global Centroid-Moment-Tensor Products

How to cite the CMT Catalog:

The Global CMT project is a research activity funded by the National Science Foundation, and we greatly appreciate users of the catalog including appropriate citations to our work in their published articles.

For general use of the CMT catalog:

Please cite the following pair of papers, which give (1) the basic methodology and approach; and (2) the most recent description of how we conduct the CMT analyses, including a number of significant improvements to the analysis.

  • Dziewonski, A. M., T.-A. Chou and J. H. Woodhouse, Determination of earthquake source parameters from waveform data for studies of global and regional seismicity, J. Geophys. Res., 86, 2825-2852, 1981. doi:10.1029/JB086iB04p02825
  • Ekström, G., M. Nettles, and A. M. Dziewonski, The global CMT project 2004-2010: Centroid-moment tensors for 13,017 earthquakes, Phys. Earth Planet. Inter., 200-201, 1-9, 2012. doi:10.1016/j.pepi.2012.04.002

For particular earthquakes or earthquake sequences:

For some earthquakes or earthquake sequences of particular interest, we have conducted focused studies; for authors relying primarily on these studies, it may be appropriate to cite the paper describing our focused study, instead of or in addition to the references given above. Some of these are described on the following web page:
Special studies of particular earthquakes or sets of earthquakes (these include, e.g., earthquakes in Haiti and the Gulf of Aden, the Tohoku earthquake and aftershocks, glacial earthquakes, etc.).

Some CMT solutions are also available for intermediate-depth and deep earthquakes from the pre-digital era; solutions for events in 1976 were calculated primarily from HGLP data. These solutions, and the analysis, are described in the following publications:

  • Ekström, G., and M. Nettles, Calibration of the HGLP seismograph network and centroid-moment tensor analysis of significant earthquakes of 1976, Phys. Earth Planet. Inter., 101, 219-243, 1997. doi:10.1016/S0031-9201(97)00002-2
  • Huang, W. C., E. A. Okal, G. Ekström, and M. P. Salganik, Centroid moment tensor solutions for deep earthquakes predating the digital era: The World-Wide Standardized Seismograph Network dataset (1962-1976), Phys. Earth Planet. Inter., 99, 121-129, 1997. doi:10.1016/S0031-9201(96)03177-9
  • Chen, P. F., M. Nettles, E. A. Okal, and G. Ekström, Centroid moment tensor solutions for intermediate-depth earthquakes of the WWSSN-HGLP era (1962-1975), Phys. Earth Planet. Inter., 124, 1-7, 2001. doi:10.1016/S0031-9201(00)00220-X
