Abstract We provide a synthesis of the long-term earthquake activity in the region of Northwest Europe between the Lower Rhine Embayment and the southern North Sea. Historical seismic activity in stable continental Europe shows patches of activity, with M ≥ 5.0 earthquakes, separated by relatively inactive regions. The activity in most of these patches is sporadic in time, showing inactive periods of hundred to some hundreds of years followed by more active periods. Only the Lower Rhine Embayment shows relatively permanent activity. An important observation is that nearly all M ≥ 5.0 earthquakes inside the different patches occurred at different locations. Therefore, we can suspect that the next earthquakes in each of these patches will occur at a location not yet affected during historical time. Because in plate interiors the present seismic activity does not necessarily reflect past and future activity, we discuss the necessity to use the geologic record to infer long-term earthquake activity. Thus, we discuss paleoseismic investigations in the Roer Graben that provide evidence that large earthquakes with magnitude 6.5 to 7.0 occurred since the late Pleistocene.
