Abstract

The East African Rift (EAR) marks the divergent boundary between the Nubian and Somalian plates, where continuous Global Positioning System (GPS) data reveal velocities of 2–7 mm/year, driving seismic and volcanic hazards. This study addresses the critical need to disseminate 10-year divergence predictions to East African communities, enhancing tectonic hazard awareness and regional planning. The purpose is to model Nubia-Somalia kinematics using Euler vector-based methods, leveraging the Euler pole at 54.8°S, 37.0°E (-0.069°/Ma), and translate findings into actionable insights. Methods involved calculating cumulative displacements (6.8 cm in the Ethiopian Rift, 5.0 cm in southern Somalia) across a grid spanning 33°E–51°E and 1°N–15°N, visualized with contour maps using Cartopy. Workshops, public reports, and digital platforms facilitated dissemination, engaging over 500 stakeholders in Ethiopia and Somalia. Findings indicate higher displacement and risks in Ethiopia (moderate to high seismic, high volcanic) versus lower risks in Somalia (low to moderate seismic, minimal volcanic), validated by 2009-2010 GPS data. Community surveys reported an 85% awareness increase, while regional plans in Ethiopia adopted earthquake-resistant codes. The conclusion emphasizes the success of integrating science with community action, enhancing resilience despite challenges like rural access. Recommendations include deploying denser GPS networks, developing mobile apps for real-time updates, and securing funding for sustained campaigns, aligning with global disaster risk reduction goals. This study bridges geodetic modeling with societal benefits, offering a model for tectonic hazard management in active regions.
