“…The Lower Rhine Embayment is a young sedimentary basin with typical intraplate seismicity (Camelbeeck et al 2007;Hinzen and Reamer 2007). The strongest instrumentally recorded earthquake in 1992 had a M W 5.4.…”

“…During the Pliocene, faulting was more intense and cumulated in late Pliocene and early Pleistocene. Considerable synsedimentary and intersedimentary crustal displacements occurred in the Quaternary when the Older and Younger Lower Terraces of the Rhine and Meuse (Maas) River were accumulated (Ahorner 1962;Hinzen and Reamer 2007). The main faults with a cumulative length of more than 400 km are generally directed in a NW-SE strike.…”

“…Palaeoseismic studies and the extension of active fault segments indicate maximum magnitudes of M W 6.8-7.0 (Camelbeeck and Meghraouhi 1998;Ahorner 2001;Schmedes et al 2005;Hinzen and Reamer 2007). The main earthquake activity in recent and historic times is found in the western part of the LRE, while Weber and Hinzen (2006) showed evidence for recent seismic activity east of the Rhine River in the form of several microearthquakes.…”

“…12 was selected for the deterministic calculation of the dynamic load in the study area. (Ahorner 2001;Hinzen and Reamer 2007), they were used as "worst cases" for the deterministic modeling of the slope stability. All earthquakes were assumed to be normal faults with a bilateral rupture and a rupture velocity of 2.0 km/s.…”

The causes of damage observed in archeological records or preserved monuments are often difficult to be determined unequivocally, particularly when the possibility of secondary earthquake damage exists. Such secondary damage has been previously proposed for the Roman Praetorium, the governor's palace in the center of Cologne. Ongoing excavations since 2007 revealed additional damage. The existing ground that has been uncovered and documented extends the affected area to 175×180 m. We present a comprehensive virtual model of the excavation area based on 200 3D laserscans together with a systematic analysis of the damage patterns and an improved model of the terrain during Roman/Medieval times including geotechnical parameters of the subsurface. Five locations with different damage patterns, including a Roman sewer, the octagonal central part of the Praetorium, a section with strongly inclined massive walls, a 13 m deep deformed well, a collapsed hypocaust, and damages in the Medieval mikveh are analyzed in detail. We use site-specific synthetic strong ground motion seismograms to test the possibility of earthquake-induced ground failures as a cause for the observed damage. This subsurface model is also used to test the possibility of hydraulically-induced damages by seepage and erosion of fine-grained material from stray sand. Heavy rainstorms can induce a direct stream of surface water through the fine sand layers to the ground water table. Simulated ground motion for assumed worst-case earthquake scenarios do not provoke slope instability at the level necessary to explain the structural damages.

“…The earthquake severely damaged the city of Basel, causing several hundred fatalities (Mayer-Rosa & Cadiot 1979). For the Lower Rhine Graben, the largest historical earthquake is the M L ≈ 6.2 Düren earthquake of 1756 (Meidow 1994;Hinzen & Reamer 2007). This event occurred only a few weeks after the M ≈ 9 Lisbon earthquake of 1755 (Babtista et al 1998) -the largest historical earthquake of the European continent.…”
