East Africa Rift Location of a continental Rift that began spreading Approximately 20 million Years ago USGS http://pubs.usgs.gov/gip/dynamic/dynamic.html

Currently, the East African Rift is considered a young continental rift zone USGS http://pubs.usgs.gov/gip/dynamic/dynamic.html

If rifting continues, seafloor spreading will occur USGS http://pubs.usgs.gov/gip/dynamic/dynamic.html
