Information sheet for composite seismic source DECS008

Name

Kirspenich fault.

Description

Composite source DECS008 corresponds to the Kirspenich fault (Figure S4). This is a ~20 km long west-dipping fault that is situated ~8 km south of the southern end of the west-dipping Rurrand fault (DECS001), and directly SE of the southernmost east-dipping border fault, the Stockheim fault (DECS007). Its southern end terminates at the same latitude as the Erft/Swist fault (DECS003), i.e. near the southern limit of the Lower Rhine Embayment.

Paleoseismic trenches

None

Vertical displacement data

Based on the map of Ahorner (1962), the long-term vertical displacement rate of DECS008 is 0.006 – 0.010 mm/yr.
