A unified M w -based earthquake catalogue and seismic source zones for the Red Sea region

•A unified Mw based earthquake catalogue of independent event is obtained for the Red Sea region.•Different magnitude were homogenized to Mw magnitude.•Seismotectonic models were obtained and the b-value and the seismicity parameters are calculated for each zone.•There is clear association of seismicity with active tectonic structures.•The catalogue stands as the bases for further calculation of seismic hazard of the region.
