Volcán Ol Doinyo Lengai (Tanzania) - erupciones de ceniza (18 de enero de 2008)

Durante 17-19 de enero, hemos logrado permanecer encima de Lengai con un pequeño grupo. Durante mucho tiempo, la Cumbre estaba en las nubes, pero el 18 de enero, la tarde resultó para ser claro y Lengai inició una fase de erupciones de ceniza, una duración de alrededor de 16 a 20. Puede encontrarse un informe detallado sobre la expedición y eliminarán del Lengai en el tiempo entre el 17 y el 21 de enero aquí.

The crater of the new ash cone on Lengai volcano. Most of the time, a very fine, dilute stream of smoke (very fine ash, probably) is issuing from its crater. Note the 3 persons on the rim in the background: (Photo: Tom Pfeiffer)

A small group of climbers, perhaps unaware of their dangerous position, have climbed via the old northern route. Note: this route is now extremely dangerous and virtually impassible for descend. In fact, the people on the photo had to descend on the southern route. Minutes after they had passed the crater, explosions started and threw rocks over the path they took.  (Photo: Tom Pfeiffer)

The group from before is trying to descend back along the old route, but will have to give up: the section beyond the rocks visible in the background is now a steep, smooth slope of hardened ash with no grip. (Photo: Tom Pfeiffer)
