Abstract

During the period of January 1977 to December 1979, 22 earthquakes were recorded and located in Sweden and/or adjacent waters by means of the Swedish Seismograph Station Network (SSSN). 8 were felt by residents in the repective areas and hence provide an opportunity for macroseismic investigations. Such investigations are extremely useful for estimating e.g. the depth of rupture and local ground accelerations, especially when teleseismic data and strong-motion records are not available. The long-term average gives approximately 3 earthquakes per year which are reported to be felt by people. In this respect, the seismic activity in Sweden during the years under review is well within the 'normal'. The main objective of the present study is to summarize and interpret available macroseismic observations collected at the Seismological Dept in Uppsala.-P.N.Chroston
