Red Sea Rifting is a marvel lab that helps us understand complex geology and tectonics. The study of seismicity is a crucial tool for deciphering the Red Sea region’s tectonic dynamics and understanding the processes driving oceanic crust formation. Integrating seismic data with geological and geophysical observations enhances our understanding of the region’s lithospheric dynamics. Analysis of Red Sea seismicity reveals a pattern of low to moderate shallow earthquakes predominantly clustered along plate boundaries and rift zones. The southern Red Sea exhibits higher seismic activity compared to the northern part, with seismic events often concentrated along spreading zones and significant fault lines. Transform faults intersecting with spreading zones contribute to localized seismic activity, while volcanic activity leads to swarm-type seismicity in western Saudi Arabia. A detailed examination of seismic data highlights the complex tectonic processes underlying the Red Sea region’s seismicity. Spatial distribution and intensity mapping over the past century demonstrate the heterogeneous nature of seismic activity, reflecting the incomplete rift system’s evolution. Tectonic features such as strike-slip faults parallel to the Red Sea’s extension, the Gulf of Suez rift, and the Najd fault system play significant roles in seismic activity distribution.
