On the seismic demarcation map of Russia ÎSÐ-97 Karelia is shown as a zone of possible magnitude 5-7 seismic activity with a recurrence period of 5000 years. Seismic activity is restricted to the Kandalaksha-Dvina paleorift and to the Ladoga-Bothnian suture zone. In spite of a relatively low seismic activity level, the detailed study of Karelia is not only of theoretical, scientific interest, but is also of practical value which has increased markedly because there are big industrial complexes, gas pipelines and hydrotechnical facilities in the region.
