SVT can reveal that measuring stations in both Sweden and Denmark registered strong underwater explosions in the same area as the gas leaks on Monday. ‘There is no doubt that these are explosions,’ says Björn Lund, lecturer in seismology at the Swedish National Seismic Network, SNSN.
The first explosion was recorded at 2.03am on the night of Monday and the second at 7.04pm on Monday evening.
The warnings about the gas leaks came from the maritime administration at 1.52pm and 8.41pm on Monday, respectively, after ships detected bubbles on the surface.
SVT has obtained the coordinates of the measured explosions and they are in the same area where the gas leaks were registered.
