The East African Rift System (EARS) represents the only actively developing continental rift observable on land, offering an unprecedented natural laboratory for understanding the processes governing continental breakup and ocean basin formation. This comprehensive review synthesizes geological, geophysical, and geochemical evidence documenting the incipient separation of the African continent into the Nubian and Somalian plates. We examine the dramatic 2005 Dabbahu rifting event, wherein a 60-kilometer fissure opened in the Ethiopian Afar region within days, demonstrating that seafloor-style spreading can occur subaerially. Seismic tomography, GPS geodesy, and noble gas isotope analyses reveal a deep-seated African Superplume originating at the core-mantle boundary (approximately 2,900 km depth) as the primary driver of lithospheric extension. The EARS extends over 6,000 kilometers from the Afar triple junction to Mozambique, with divergence rates of 6–7 mm per year along the eastern branch. Current models project complete continental separation and marine inundation within 5–10 million years, creating a new ocean comparable to the Red Sea, with eastern Africa (Somalia, coastal Kenya, Ethiopia, Tanzania) forming an independent microcontinent.

The East African Rift (EAR) or East African Rift System (EARS) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. It is considered to be part of a larger system, formerly known as the Great Rift Valley, that extends north to Asia Minor, also known as Anatolia.

The EAR began developing around the onset of the Miocene, 22–25 million years ago. It is considered to be part of a larger system, formerly known as the Great Rift Valley, that extends north to Asia Minor, also known as Anatolia. A narrow zone, the rift is a developing divergent tectonic plate boundary where the African plate is in the process of splitting into two tectonic plates, called the Somali plate and the Nubian plate, at a rate of 8–9 mm (0.31–0.35 in) per year. The rift system consists of three microplates, the Victoria microplate to the north, and the Rovuma and Lwandle microplates to the south. The Victoria microplate is rotating anti-clockwise with respect to the African plate. Its rotation is caused by the configuration of mechanically weaker and stronger lithospheric regions in the EARS. Many of the African Great Lakes lie within the Rift Valley. The Rift Valley in East Africa has been a rich source of hominid fossils that allow the study of human evolution. The rapidly eroding highlands quickly filled the valley with sediments, creating a favorable environment for the preservation of remains. The bones of several hominid ancestors of modern humans have been found here, including those of "Lucy", a partial australopithecine skeleton discovered by anthropologist Donald Johanson dating back over 3 million years. Richard and Mary Leakey have also done significant work in this region. In 2008, two other hominid ancestors were discovered here: a 10-million-year-old ape called Chororapithecus abyssinicus, found in the Afar rift in eastern Ethiopia, and Nakalipithecus nakayamai, which is also 10 million years old.

Malawi lies within the southern segment of the East African Rift System and is exposed to infrequent but potentially damaging earthquakes. While recent advances in fault mapping, seismic monitoring, and hazard modelling have substantially improved scientific understanding of earthquake hazard in the Malawi Rift Zone, the practical reduction in seismic risk remains limited. This Perspective paper argues that earthquake resilience in Malawi is constrained less by scientific uncertainty than by challenges in integrating existing hazard knowledge into governance, planning, and preparedness. Drawing exclusively on published geological, geophysical, engineering, and policy literature, the paper synthesises evidence on seismic hazard, historical earthquake impacts, institutional preparedness, and barriers to the operational use of scientific risk assessments. An integrated, multi-pillar framework is proposed to support improved coordination between science, governance, infrastructure practice, and community preparedness. The framework is conceptual in nature and is intended to inform policy dialogue, prioritisation, and future empirical research rather than to provide a validated operational model. While grounded in the Malawian context, the insights presented are relevant to other low-income, rift-hosted regions facing similar challenges in translating earthquake science into effective disaster risk reduction.
