Abstract

The maximum magnitude, the activity rate, and the Gutenberg-Richter b parameter as earthquake hazard parameters, have been evaluated for Sweden. The maximum likelihood method permits the combination of historical and instrumental data. The catalog used consists of 1100 earthquakes in the time interval 1375-1989. The number of annually expected earthquakes with magnitude equal to or larger than 2.4 is 1.8 for the whole of southern Sweden, 1.3 for the Lake Vanern region, 3.7 for northern Sweden, and 2.4 for the region along the Gulf of Bothnia. The maximum expected regional magnitude is calculated to 4.9 (0.5) for a time span of 615 years for southern Sweden and the Lake Vanern subregion, and 4.3 (0.5) for a time span of 331 years for northern Sweden and the Gulf of Bothnia subregion. However, several historic earthquakes with magnitude above 5 in nearby areas of Norway indicate that the seismic potential may be higher. -from Authors
