The Swedish national seismic network picked up two explosions within kilometers of the reported gas leak locations yesterday.
The time of the first explosion: Yesterday, Monday morning at 02:03 am, second one Monday evening at 7:04pm (local time, CEST).
The reports of the gas leaks came at 1:52pm and 8:41pm, respectively - by means of ships reporting bubbling at the surface level.
One of the two events registered at magnitude 2.3. They were picked up by stations all over the country.
It's clear from the registered seismic waves that the events are not earthquakes.
- You can clearly see how the waves bounce from the bottom to the surface. There is no doubt that it was a blast or explosion. We even had a station in Kalix [quite far up north, some 1300 km away] that picked this up, says Björn Lund, who is a lecturer in seismology and director of the Swedish national seismic network, which measures Swedish earthquakes and explosions.
