Seismic observation

Tehostekuva

The Finnish national seismic network records annually about 3000 teleseismic earthquakes and over 5000 regional/local events. Most of these are explosions, but some 100 events are local earthquakes with 10-15 of them occurring in Finland. Preliminary analyses and final bulletins of regional events are given on the seismic reports.

The first known observation of an earthquake in Finland is from the year 1610. Probably the greatest damage was caused in 1626 by an earthquake in Paltamo (64.5 N, 27.0 E) where the church was badly damaged. The magnitude has been calculated to 4-5.
