Ol Doinyo Lengai volcano (Tanzania) - Smithsonian / USGS Weekly Volcanic Activity Report for 5 September-11 September 2007 (New Activity / Unrest)
An eruption of Ol Doinyo Lengai on 4 September produced an ash plume that was reported by a pilot and visible on satellite imagery. Ashfall lasted about 12 hours in the village of Engare Sero, about 18 km N. Dark areas on the NW, W, and E flanks that were noticeable on satellite imagery from 4 September were possibly due to recent lava flows and burned vegetation or both.

An ash plume was also visible, drifting SSW.
Multiple thermal anomalies at and around the summit were present on satellite imagery since 21 August 2007, and on the flanks on 31 August and 1 September.

Ol Doinyo Lengai volcano (Tanzania) - Smithsonian / USGS Weekly Volcanic Activity Report for 25 July-31 July 2007 (New Activity / Unrest)
Ol Doinyo Lengai is frequently the scene of fluid but very small volume lava flows in its summit crater, including a few that passed over the crater rim and begun the long descent down the mountain. As noted here last week, news reports had indicated that products of the volcano's 19-July eruption had entered inhabited areas. Subsequent investigations have cast doubt on those earlier claims. ...

As more news has become available, the news about an effusive flank eruption at Lengai around 15 July turns out to be probably false. The observed "ashcloud" was dust from a landslide. This demonstrates how difficult it is in this area to have robust information. The ongoing seismic activity in the Gregory Rift, however, is quite peculiar. Read all
