Seismic waveform data digitally recorded at the Borovoye Geophysical Observatory (BRV), in northern Kazakstan since 1966 are available for analysis. The BRV archive for 711 Underground Nuclear Tests* (UNT) carried out by five nuclear powers since 1966 are reformatted into CSS 3.0# data format. The list of event numbers in the BRV archive for UNTs from various test sites is given in Table 1 and are plotted in Figure 1.
A major digital seismogram archive at Borovoye is being reformatted into a modern format suitable for analysis and preservation. Since 1991, the authors at the Lamont-Doherty Earth Observatory (LDEO) and at the Institute for Dynamics of Geosphere (IDG), Moscow have worked hard under the auspices of the IRIS Consortium, the Air Force Office of Scientific Research and Defense Threat Reduction Agency, U.S. Department of Defense, International Science and Technology Center (ISTC), Moscow, and other organizations to preserve the 30 years of digital seismogram archive at BRV (see a feature article in EOS by Richards, Kim and Ekström, 1992).
This release of the BRV digital seismogram data archive
results from nearly 10 years of hard work by many engineers and
analysts at IDG, Moscow. Drs. Nadezhda Belyashova and Natalia Mikhailova
at the Institute of Geophysical Research, National Nuclear Center (NNC),
Republic of Kazakstan helped to complete the BRV archive tape presevation
project. Drs. Gregory van der Vink and David Simpson at the IRIS Consortium
provided important help during the early years of the BRV archive preservation
This note describes certain information regarding these waveform data
archive and provides basic parameters needed to analyze them.
