A quake with that magnitude occurs approximately once a year in Sweden, according to Lund. But a quake with a slightly larger magnitude – 3.1 – occurred already this year in May, south of Skellefteå.
Sunday's quake had its epicenter in Lake Vänern. The rescue service in Bergslagen reports to TT that they are not aware of any alarms related to the quake.
Initially, the European Seismological Centre EMSC reported a magnitude of 2.9. But the official figure landed on 3.0.
How does a quake with that magnitude feel?
It shakes quite hard. Quakes of that size usually can be felt maybe five miles away. So far, we've only received reports that it was felt in Otterbäcken and Gullspång, says Lund.
It can rattle window glass and porcelain cabinets, but not more than that.
According to Lund, it's not unusual for quakes to occur in that area.
There's a fault line from the northern part of Västra Götaland from Falköping and northwards through Lake Vänern and through both Dalsland and Värmland towards Norway that has quite a lot of quakes.
In the seismological network, two to three earthquakes per day are registered. But only 20 to 30 annually reach a magnitude that can be felt, according to Lund.
The largest quake measured in Sweden, which is known with certainty, occurred off the Koster Islands in 1904 with a magnitude of 5.4.
