Global Volcanism Program | Image GVP-00159

The trachytic Longonot stratovolcano SE of Lake Naivasha contains an 8 x 12 km caldera.  A large central cone, seen here from the SW, was constructed within the caldera and forms the summit of the volcano.  It is truncated by a circular, 1.8-km-wide caldera.  Post-caldera lavas erupted onto its floor give it a flat surface.  Masai tradition records a lava flow on the northern flank during the 19th century.  Similarly youthful-looking lava flows occur on the SW flank.    Copyrighted photo by Katia and Maurice Krafft, 1976.
