Comment on 'Zemmouri earthquake rupture zone(M_w 6.8, Algeria): Aftershocks sequence relocationand 3D velocity model' by A. Ayadi et al.

摘要

Although often difficult to characterize, the relationshipbetween a seismic rupture, its aftershock sequence, and cu-mulative subsurface or surface faulting or folding is an im-portant challenge to modern seismology and seismotectonics.Among other benefits, it helps document fault length, slip,and magnitude relationships, reconstruct the evolution of therupture process through historical and prehistorical times andidentify the complexity of the deformation in its path towardthe surface. This approach is a prerequisite to any seismichazard assessment but is particularly difficult for faults whosesurface trace projects offshore. A specific effort to identifyand quantify the source parameters of large earthquakes incoastal areas is therefore needed, not only in subduction zonesbut also in areas of slow rate and/or diffuse deformation.
