A mild earthquake measuring 2.5 in the Richter scale shook the Kuusamo area on Thursday afternoon, said the Institute of Seismic Observatory of the Helsinki University.
Although it was this year’s second biggest quake, seismologists said it got mostly unnoticed by the people of the locality.
The epicentre of the tremor was in the southern part of Kuusamo, but at least one observation was made in the neighbouring municipality of Taivalkoski side.
“The duration of the quake was very short but was detected clearly,” Seismologist MattiTarvainen told STT.
In the recent decades, the most powerful jolt in Finland was the one that took place in 1979 at Alajärvi in South Ostrobothnia. That was a 3.8 quake.
