 Overview from the summit on the active North crater. On the left: scarp of the Eastern Rift Valley; in the background the sodic lake Natron (18.12.95). |  General view from inside the crater with activity of the cinder cone just before flank collapse (see also photo below; 17.12.95). |  Filming of very thin (few centimeters) carbonatitic lava flows issued from one of the hornitos (17.12.95). |  Active carbonatitic lava channel, flow from top to bottom of picture, where the channel is almost closed forming a «micro» lava tube (17.12.95). |
 Spattering from a small hornito, about 2 meters tall (17.12.95). |  Strombolian activity inside the large cinder cone just after flank collapse (height about 12-15 meters). |  Spectacular bubbling from a carbonatitic hornito (17.12.95). |  Very rapid, dangerous lava flow (approx. 1 m thick), transporting large blocks. Sequence approx. 5 mins, taken from E rim. |
