Test No.=unique test id number given in Mikhailov et al. (1996) for nuclear tests in USSR; Body-wave magnitude, m (P), from Marshall et al. (1994); location and origin time from Marshall et al. (1994) and Richards (2000). Inst. type= instrument used; KODB= KOD low-gain system; KODM= KOD high-gain system; SS=STsR-SS system; TSG=STsR-TSG system. salvo exp.= salvo explosion means two or more separate explosions where a period of time between successive individual explosions does not exceed 5 seconds and where the burial points of all explosive devices can be connected by segments of straight lines, each of them connecting two burial points and does not exceed 40 kilometers in length.
