Swedish broadcaster SVT reported that the Swedish National Seismic Network detected two underwater explosions near the Nord Stream pipeline system on Monday. “One of the explosions had a magnitude of 2.3, and was registered at as many as 30 measuring stations in southern Sweden,” SVT said. Bjorn Lund, a professor in seismology and director of the Swedish National Seismic Network, said these two seismic events were explosions. Here’s a map of the three leaks on the Nord Stream pipeline system.
