Danish media recently reported that the police have received complaints from the public regarding tremors occurring on the eastern part of Bornholm Island.
Danish scientists are currently perplexed by a succession of tremors originating from the Baltic Island of Bornholm. They believe that these tremors are caused by "acoustic pressure waves from the atmosphere." Despite their efforts, the scientists have been unable to identify the precise origin of this enigmatic geological occurrence.
The tremors reported by residents on Bornholm were described as deep rumbling, shaking, rattling, and changes in ear pressure. At first, there was a mistaken belief that these tremors might be caused by earthquakes. Seismologists initially speculated that controlled explosions in Poland, located approximately 90 miles (145 km) south of Bornholm, could be the source.
However, on Monday, the Geological Survey of Denmark and Greenland (GUES) clarified that the tremors were not seismic in nature. Instead, they determined that the tremors were caused by pressure waves originating from an atmospheric event. The exact source of these pressure waves, however, remains unknown at this time.
"The seismologists can report that it is unlikely that the tremors originate from a controlled explosion in Poland, which was carried out shortly before the first reports of tremors on Bornholm," the body known as GEUS said in a statement.
Polish authorities have mentioned that there was significant activity during the Anakonda23 exercise in Ustka, located in northern Poland, which involved jet fighters and live artillery munitions.
GEUS, an independent research and advisory institution under Denmark's Ministry of Climate, Energy, and Utilities, stated that it operates two seismographs on Bornholm Island that continuously collect data.
Bornholm, a rocky island situated in the Baltic Sea, is home to approximately 40,000 residents. It is located south of Sweden, northeast of Germany, and north of Poland.
