Intraplate Seismic Activity in the Brabant Massif and the Graben Systems of Lower Rhine-Roer and Norte for magnitude 6 earthquakes in the total region is of the order of 60–100 years. Locally this time of recurrence is 10–100 times longer. Co-operative measures in seismic data acquisition and exchange, and in scientific investigations in the field are advocated

The Earthquakes of Liege of November 8, 1983 and December 21, 1965f the local magnitude determined by the coda duration measurement at the belgian seismological stations is M. = 5.0 which is comparable to the values given by other networks..Supposing the source being a circular crack, the radius has been estimated to 1200 m, the stress drop to 40 bars and the seismic moment 1.5 10. dyne.cm.
