The Geological Survey of Denmark and Greenland (Geus) said the tremors “were not caused by earthquakes, but by acoustic pressure waves caused by an event in the atmosphere.”
A series of small tremors recorded on the Danish island of Bornholm in the Baltic have caused concern and concern among officials.
Initially, some tremors last Saturday were thought to be caused by earthquakes. But then seismologists thought they came from controlled explosions in Poland, more than 90 miles (140 kilometers) to the south.
Today, Monday, the Geological Survey of Denmark and Greenland (Geus) said the tremors “were not caused by earthquakes, but by acoustic pressure waves caused by an event in the atmosphere”. However, what event they came from remains unknown.
“Seismologists can report that it is unlikely that the tremors came from a controlled explosion in Poland, which took place shortly before the first reports of tremors in Bornholm,” Geus said.
On Saturday, The Institute said it had received “more than 60” messages from people in Bornholm about “earthquake-like vibrations” – described as a deep rumbling, shaking and rattling.
In fact, according to the Danish media, the vibrations also caused a crack in the wall of a house.
According to the Geological Survey of Denmark and Greenland the tremors had a corresponding magnitude of 2.3 Richter
It is noted that the island is very close to the place where the sabotage took place on the two Nord Stream pipelines, which transported natural gas from Russia to Germany,
