The Ethiopian Rift Valley

The African rift valley is one of the most fascinating natural wonders, known for its unique biodiversity and for being considered -for the important paleoanthropologic discoveries- the "cradle of mankind", i.e. the place where our species has evolved and diversified in the last millions of years. Characterized by a system of linear valleys extending for thousands of kilometers, the rift valley is a huge fracture on the surface of our planet that progressively widens with time, tearing the eastern portion of the African continent apart. It represents a geological wonder where volcanism, earthquakes and fracturing of the Earth's crust are the surface expressions of the enormous forces that shape our planet. These web pages are dedicated to the analysis of the Ethiopian sector of the African rift valley, an ideal natural laboratory to analyze the evolution and dynamics of continental extension and the rupture of lithospheric plates.

Starting from a study in highlands of Colombia and Ethiopia, scientists have shown that malaria moves up in elevation in warmer years implying that "climate change will, without mitigation, result in an increase of the malaria burden in the densely populated highlands of Africa and South America".
