Ol Doinyo Lenai volcano (Tanzania), eruption news: large summit eruption, lava overflows and ash plume (?)Thursday Sep 06, 2007 13:47 PM | Age: 5 yrs
 Satellite image of the eruption at Lengai volcano (image: NASA/GSFC/METI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team) A large eruption seems to be taking place at Lengai volcano, this time for real: On 4 Sept., reports started coming in that a large (natrocarbonatite?) lava flow is descending the West flank. A considerable ash plume was visible on satellite data.
Over 30 thermal anomalies have been detected by the MODIS team since August 23 - more than during the large eruption in March 2006. On 4 and 5 Sep, the thermal anomaly at the summit was extremely strong. From this and satellite imaginery, it seems that there was a short overflow to the East and a major overflow to the West starting on September 1st (it could be a bush fire on the volcano flank ignited by lava). New overflows on 5 Sep seem to be taking place on the W and NW flanks.
