Arriving at the crater terraces. Natrocarbonatite lava and ash becomes quickly white. The steep cinder cone T56B is covered by fresh black material stands out from a unearthly landscape with old strange cones and white ash dunes. |

3-4 August 2003: collapse of T56 and rebuilding the cone |
|
|
|
|
 |
| Late on 2 August, the top of hornito T56B had collapsed, plunging as a whole piece silently into the hollow conduit beneath. Now the toppled cone quickly resumes its reconstruction, producing dense lava fountains up to 15 m high and ash eruptions up to 50 m high. Photos taken on 3 August. | 4 August: Strong fountains continues at T56 on 4 August, rebuilding its steep narrow vent, ready for a next collapse. | ||
