Access to Waveforms From Nuclear Explosions (WFNE) is not currently available

The WFNE consists of source information (date/time, location, yield, seismic magnitude, burial depth, etc.), drawn from a variety of official and unofficial sources, and a collection of related digital waveform data for all nuclear explosions conducted from 1945-2017. The WFNE website includes 2,157 announced or presumed nuclear explosions, 1,113 of which have 152,885 digital waveforms available from WFNE (in CSS and SAC formats), recorded at 524 stations distributed worldwide.

All the data available via WFNE are from open and publicly released sources. All the IMS data contained in this version of the WFNE are from open IMS stations and can be freely accessed and processed by approved users.

A range of options are provided for accessing/downloading these data resources including menu-based and map-based alternatives. For a complete description of the WFNE data resources and access tools, the WFNE User Manual provides an orientation and guide including a summary of what data are available, functionality of various web-based access and display options, and step-by-step examples for several typical WFNE data queries.
