D. Prinz et al., THE SEISMIC ACTIVITY NEAR AACHEN FOLLOWING THE 1992 ROERMOND EARTHQUAKE, THE NETHERLANDS, Geologie en mijnbouw, 73(2-4), 1994, pp. 235-240
The seismic activity following the large Roermond earthquake of April
13, 1992, was concentrated in the area of the main shock and, surprisi
ngly, a few kilometers northeast of Aachen. The locations and source p
arameters of 13 earthquakes, which occurred in the Aachen area, are pr
esented. The evaluation is based mainly on seismograms from four mobil
e seismograph stations of the RWTH Aachen (Rheinisch-Westfalische Tech
nische Hochschule) which were installed close to the epicenters. Fault
-plane solutions were determined for two of these earthquakes.
