This study investigates the impact of the AD 365 Crete Earthquake on the Libyan coast, with particular emphasis on the geological and topographical changes induced by this significant historical event. The research examines the relationship between tectonic activity and the distribution of hydrocarbon basins in Libya, highlighting the role of tectonic faults in the formation, accumulation, and spatial distribution of hydrocarbon resources. Furthermore, the study discusses the impacts of climate change and sea-level rise on the Libyan coastal zones, providing recommendations for future planning and sustainable development to address these environmental challenges. The findings indicate that effective urban planning and comprehensive natural disaster risk reduction strategies are fundamental to protecting coastal communities and ensuring their long-term resilience against increasing natural hazards.
