The Afar Rift, Ethiopia
How does the Earth's crust grow at divergent plate boundaries? A unique opportunity in Afar, Ethiopia.
In the remote Afar depression in northern Ethiopia, the African Continent is slowly splitting apart and a new ocean is forming.
In September 2005, a series of fissures opened along the Afar Depression. Over about a week, the rift pulled apart by eight metres and dropped down by up to one metre. Local people told of a series of earthquakes and how ash darkened the air for three days. At the same time, satellites tracking the region showed that the surface about nearby volcanoes subsided by as much as three metres, as magma was injected along the fissure.
This process of ocean formation is normally hidden deep beneath the seas, but in Afar we can walk across the region as the Earth's surface splits apart.
Over the next five years, this web site will detail the work of scientists from the U.K., Ethiopia and the U.S. who have come together to conduct a major set of experiments in this unique natural laboratory, to further understand the processes involved in shaping the surface of the Earth.
