Measuring stations in Sweden and Denmark registered two strong underwater explosions shortly before gas leaks were discovered on Russia's Nord Stream 1 and Nord Stream 2 pipelines in the same area on Monday. This is reported by SVT.
The Swedish National Seismic Network detected two apparent explosions in the area of the gas leaks on Monday. One of the explosions had a magnitude of 2.3 and was registered at 30 measuring stations in southern Sweden.
"You can clearly see the waves bouncing from the bottom to the surface. It was definitely an explosion," said Björn Lund, a seismology lecturer and director of the Swedish National Seismic Network, which measures Swedish earthquakes and explosions.
The first explosion was recorded at 02:03 on Monday night, the second at 19:04 on Monday evening.
The gas leak was reported by the maritime administration at 1:52 p.m. and 8:41 p.m. on Monday after ships detected bubbles on the sea surface.
SVT has the coordinates of the recorded explosions and they are in the same area where the gas leak was reported.
According to Björn Lund, the information about the explosions was passed on to the Armed Forces of Sweden.
