Segmented Waveform Data
The United States National Data Center forwards all station data authorized for public release to the United States Geological Survey (USGS) which, in turn sends it to Incorporated Research Institutions for Seismology (IRIS). Data requests must be directed at the IRIS AutoDRM page located here: http://www.iris.edu/manuals/autoDRM.htm
Government agencies and contractors requiring additional waveform data in the performance of government contracts may submit a request by email to data@usandc.gov. Department of Defense contractors please include as much information as possible about your company and government contract in your request to expedite approval.
