Abstract
In the years 1963-79, altogether 176 Swedish earthquakes have been detected and located. The earthquakes have occurred within a belt from the SW to the NE part of the country and in N Lapland. Corresponding local magnitudes are not greater than 4. b-values of the magnitude-frequency relation are 0.7 and 1.5 for magnitude intervals 2.2-3.0 and 3.0-3.9, respectively. The strain energy release has been rather regular during most of the time. The apparent increase of small-size shocks in recent years is due to improved instrumental facilities and not to a real increase of seismicity. The presented data can be used as a base for seismotectonic and seismodynamic studies of the Swedish bedrock.-from Author
