Details for: Olkaria
Volcanic vents of the northern part of the Olkaria volcanic complex are visible immediately south of Lake Naivasha (upper right). The complex comprises up to 80 individual commenditic and other peralkaline rhyolitic centers, many of which are visible in this Landsat image. The youngest known eruption has a radiocarbon age of about 180 years. Fumarolic activity occurs at the Njorowa Gorge and at the Orengingnai and Orkaria (Olgaria) pumice cones.
