Rift Valley Earthquakes, East Africa - John Seach

A cluster of shallow focus earthquakes has been recorded in the Rift Valley in Tanzania. From Thursday 12th July to Tuesday 17th July there have been 11 earthquakes greater than magnitude 4. The largest earthquake was magnitude 6 and was felt up to 200 km from the epicenter. The earthquakes were located close to Ol Doinyo Lengai volcano in Tanzania. Some high-rise buildings in Nairobi, about 155km away, are reported to have shaken gently for several minutes. In Arusa, Tanzania thousands of residents raced into the streets. The Rift valley is subject to both earthquakes and volcanic eruptions, although activity has been low in recent years. Volcanoes within 200 km of the earthquake epicenters include Ol Doinyo Lengai, Meru, Kilimanjaro, Chyulu Hills, Suswa, Olkaria, and Longonot. If the earthquakes indicate magma movement in the rift valley, increased volcanic activity is most likely to occur at Ol Doinyo Lengai volcano, although other nearby volcanoes may be affected.
