| Abstract | ||
| Historical earthquakes catalog, which were felt in the Stable Continental Regions (SCRs) of the Arabian plate for the period (600 to 1900 A.D.), was compiled. The spatial distribution of these earthquakes appears as clusters of events in the northeastern parts, and absence of events in the other parts. This may be attributed to concentration of the population centers in the northern parts relative to other parts and / or to that the seismicity level is very low. These events have a shallow focal depths. This is a characteristic feature of the SCRs. The cumulative strain release curve exhibits two periods of high seismicity separated by low seismicity period. There is a relative quite period extends from (1194 to 1900).This quite period may appear hiatus in seismic activity or in the documentation . The b–value in magnitude relationship was low and this low value is a characteristics feature of the SCRs earthquakes. | ||
