“I was at home surfing on my computer when I felt everything start to shake. It started to rattle as if a train was going past and continued for 15-20 seconds, maybe longer. I had time to become really scared, anyway,” said Malin, who lives in the eastern parts of Skellefteå, to the TT news agency.
“When it was over the birds started to chirp in confusion,” she said.
The first preliminary details show that the epicentre of the quake lay somewhere between Skellefteå and Luleå, according to Reynir Bödvarsson at the Uppsala seismology institute.
“We get one of these strong ones each year somewhere in Sweden. This area is one of those which experience the most earthquakes in the country,” he said.
The police fielded a number of calls from people wondering what was occurring.
“Around 20 people have called and wondered what was happening. But there are no injuries recorded as far as I know,” Dan Jones at Västerbotten police said.
The earthquake occurred at around 10.30pm, shortly after the end of the Brazil-North Korea World Cup match.
The news of the earthquake spread rapidly across Swedish social media websites with a new Facebook group entitled: “Those of us who felt the legendary earthquake”, attracting over 2,000 members by Wednesday morning.
