Researchers in Norway shared seismic evidence of the four explosions, becoming the first national body to publicly confirm the second two detonations and revealing a detailed timeline of events.
The recently discovered additional explosions took place in an area north-east of the Danish Baltic island of Bornholm about seven seconds and 16 seconds after the two previously known detonations.
Using information from seismic stations in northern Europe and Germany, including the Swedish National Seismic Network and Danish stations on Bornholm, seismologists deployed advanced analysis techniques to pinpoint the blasts.
Seismologists at Norsar, Norway's national datacentre for the comprehensive nuclear test ban treaty, told the Guardian they had so far found four explosions - one south-east of Bornholm and three north-east of the island.
