Digitized Analog Seismic Data of Nuclear Explosions and Earthquakes

Digitized Analog Seismic Records from Former Soviet Union

Seismic data from nuclear tests, chemical explosions and earthquakes recorded at analog seismographic stations in former Soviet Union (FSU) are available in CSS3.0 relational database with raw digitized waveforms in SAC format.

Notice, 20 February 2015 - New information is acquired for instruments used in FSU. Hence, we are updating the instrument responses used in the digitized analog archive. CSS3.0 relational database files, .instrument, .sensor, and .sitechan are being updated. We will remove this notice when updated archive data are uploaded here.
