There are bad vibrations, like the ones felt all over Bornholm on May 13 – the result of a passing Russian fighter-jet, according to experts – and then there are good vibrations, of the Brian Wilson variety, which can currently be felt in Amager.

Should you be wondering why 20-second vibrations have caused your morning cup of coffee to splash all over your hand, then take a look outside – there’s a good chance you’ll see one or two white trucks passing by.

No, it’s not the Truman Show crew passing by after another tiring night cleaning up, rather the geothermal energy company Innargi, which has been mapping the island since May 15 to locate the best points of entry for sourcing the bubbling groundwater with a view to one day heating many of our homes with its natural warmth.

This could all mean you’re literally living on a hotbed – so not figuratively due to surging housing prices for a change.

Orange poles mark the spot
The more eagle-eyed among you might have noticed small orange poles submerged in flowerbeds near your home. Once placed, the geophones’ vibrations will indicate the geothermal potential below.

Their focus might currently be on Amager, but the Innargi trucks plan to drive around the entire Copenhagen region, covering 186 km across 17 municipalities by the end of June.

They are carrying out their work between 22:00 and 06:00 at night, so as not to disturb the daily traffic flow, normally in a convoy of four trucks. According to Innargi, the vibrations are not dangerous in any way.

Among the many roads that will be covered are HC Andersens Boulevard, Åboulevard, Jagtvej, Borups Alle, Amager Strandvej, Vesterbrogade, Østerbrogade, Gothersgade, Kongens Nytorv and stretches of the the Hillerød motorway.
