``Mysterious vibrations'' are detected on a remote island in Denmark, officials explain that ``sound waves from unknown sources'' are the cause

On May 13, 2023, a mysterious earthquake-like vibration was observed on the Danish

island of Bornholm in the Baltic Sea. The Geological Survey of Denmark and Greenland (GEUS) , a geological research institute, states that the cause of the vibrations is 'sound waves from an unknown source.'

Bornholm is a Danish island in the Baltic Sea, sandwiched between southern Sweden, Germany and Poland, and has a population of about 40,000. On the afternoon of May 13, a 'series of small tremors' was observed on Bornholm.

According to the GEUS seismometer on Bornholm, the quake was equivalent to a magnitude of 2.3. Vibrations were detected on the east side of Bornholm, and while some houses cracked walls, no one was injured.

Initially, it was thought that the tremors were caused by earthquakes. However, later, a seismologist said, ``A 'controlled explosion' occurred in Poland more than 140 km south of Bornholm, and this caused vibrations on Bornholm.''

On May 15, two days after the observation of the vibrations, GEUS announced the results of a survey that ``the vibrations are not due to earthquakes, but to pressure waves caused by events occurring in the atmosphere.'' However, the source of the pressure waves has not been identified, and GEUS only mentions an 'unknown source.'

In a statement, GEUS said, 'Seismologists report that the tremors are unlikely to have come from a 'controlled explosion' that occurred in Poland shortly before the first tremors were reported on Bornholm. You can,' he said. In the survey, GEUS said that it collected more than 60 testimonies from residents of Bornholm Island, such as 'deep rumbling', 'rattling vibration', 'pressure change in the ear'.

The Polish authorities announced that military exercises were being held in Ustka in northern Poland around the time the tremors were detected on Bornholm, and that intensive activities such as jet fighter flights and live artillery fires were taking place. I'm here.
