The coseismic offsets were determined to be between less than 0.5 m per event. Our study shows that the Rurrand Fault currently accommodates deformation in earthquakes rather than by creeping. In contrast to earlier studies on the same fault, we found evidence for a surface rupturing earthquake in the Holocene, and we identified at least one more surface rupturing event. In this study we document palaeoseismological data from the nearby Rurrand Fault. In 1755/1756, a series of strong earthquakes caused significant destruction in the city of Düren (Germany) and the surrounding areas. Destructive earthquakes are rare in the study area, but did occur in historic times. Palaeoseismological studies are needed to constrain slip rates and the earthquake history of such faults. Instrumental seismicity does only cover a small fraction of the very long earthquake recurrence intervals of several thousands of years. The faults in this area have slip rates of less than 0.1 mm yr −1, which does not allow to investigate ongoing tectonic deformation with geodetic techniques, unless they cover very long time spans. The Lower Rhine Embayment in Central Europe hosts a rift system that has very low deformation rates.
