During 1998 there were some problems with attacks by Somali bandits in the Rift Valley around Ol Doinyo Lengai, but I was lucky enough to visit the region twice without incident. I spent July 17-21 and August 2-6 camped inside the crater of Ol Doinyo Lengai with my Tanzanian guide, Paul Mongi. There was a great deal of activity at two hornitos on the crater floor, which have been designated on crater maps as T48 and T37N1. In this slide show you'll see details of those exciting eruptions. For more details, read the Smithonian Global Volcanism Network Reports which can be accessed from my links page.
