one line seismic vibrations low intensity in danish island Bornholm in the Baltic has caused concern among scientists who claim the tremors were caused by “acoustic pressure waves from an unknown source”.

Initially, experts believed that shocks were caused by earthquakes. However, seismologists subsequently assessed where they came from. from controlled explosions in Poland, over 140 kilometers from Bornholm, a rocky island of 40,000 inhabitants, in the Baltic Sea, south of Sweden and north of Poland. However, this scenario also had to be refuted.

Yesterday, on Monday, the Geological Survey of Denmark and Greenland (Geus) announced that the shocks “were not caused by earthquakes, but by pressure waves from an episode in the atmosphere.” However, the source of the episode they originated from “remains unknown”.

Seismologists report that vibrations are unlikely to come from a controlled explosion in Poland, which took place shortly before the first shocks were reported in Bornholm,” Geus notes, specifying that micro-earthquakes of magnitude 2.3 on the Richter scale.

Although the police received several reports of tremors, there were no casualties from seismic activity. Danish media reported that a crack had formed in the wall of the house as a result of the incident.

During the Anakonda23 exercise in Ustka, in the north of the country, there was a lot of activity, including overflights of fighter jets and live fire, according to Polish authorities.
