The region contains diverse tectonic regimes. We present a brief summary of the seismotectonics of these areas and their relation to earthquake occurrence. The seismological recording networks in the different Arab countries are also extremely diverse in quality and distribution of instruments. In some countries, such as Algeria, Djibouti, Egypt, Iraq, and Morocco, seismology is already well established. In others, such as Jordan or Saudi Arabia, there are either isolated stations or plans for a network, while in Libya, Sudan, and Syria there is as yet no seismological recording. We discuss plans for the future development of seismological recording throughout the Arab region.--Modified journal abstract.
