When earthquake?

Finland is not close enough to the edges of tectonic plates, so if we get earthquakes here at all, they're barely noticeable.

..and caused by the sea bed rising after it was compressed because of the weight of the glacier during the ice age

Not being close to a plate does not necessarily mean only small quakes.

There were a series of what today would be absolutely devastating earthquakes in the Midwestern U.S., far from any tectonic plates, between 1811 and 1812.

Being in the middle of the large and relatively stable Eurasian plate does help, though. The Mediterranean region, being closer to the edge region, does experience quite a bit more, though, and some strong ones have historically been felt all the way up here, too.
