Two large historical earthquakes in Fennoscandia still large

Recent studies have claimed that two of the largest earthquakes in Fennoscandia, in 1759 and 1819, should have their magnitudes reduced by 0.5 and approximately 1 Ms units, respectively. It is shown that there is no cause for these downgradings in the macroseismic data and the implications of reduce...

Summary:Recent studies have claimed that two of the largest earthquakes in Fennoscandia, in 1759 and 1819, should have their magnitudes reduced by 0.5 and approximately 1 Ms units, respectively. It is shown that there is no cause for these downgradings in the macroseismic data and the implications of reduced seismic hazard and risk for Fennoscandia are unwarranted. <copyright> 2004 Elsevier B.
