%X We study the 20 October 2004 Mw 4.4 Rotenburg (Wumme)/Neuenkirchen earthquake, located in a previously aseismic region in the northern German  sedimentary basin. We constrain the source parameter by using different techniques.  A possible relationship between this event, the regional tectonic setting, and local  gas recovery is investigated. Different waveform inversion and modeling approaches  constrain the depth of the mainshock between 5 and 7 km. The source mechanism  was oblique normal faulting on planes striking roughly north–south. An inversion  for kinematic rupture parameters indicates a unilateral rupture propagation toward  the north, consistent with the higher macroseismic intensities found toward the north  in the region of Hamburg compared with those at a similar distance toward the south  in the region of Hannover. Relocations of the mainshock and three of the largest  aftershocks indicate that these events occurred within a few kilometers of three major  gas fields and at depth close to gas production intervals. Comparison with seismicity  triggered in the northern Netherlands by depletion of similar gas reservoirs in a  similar tectonic environment suggests that the Mw 4.4 Rotenburg event may be related  to gas recovery.
