Nabro eruption calming down? 14 June 2011Posted by admin in activity reports, Africa, Eritrea, eruptions, Nabro.
[Just a quick update on the Nabro eruption, as I have a busy day today.] Satellite images of Eritrea and Ethiopia this morning seem to show a quieter situation at Nabro, the Eritrean volcano that began erupting on Sunday night and produced an impressive plume yesterday. No sign of such a plume today: on first examination it’s difficult to distinguish any volcanic emissions from surrounding cloud. Below are two images from Sat24.com, showing the situation at 07:30 UTC this morning. The likelihood is that this event is a fissure eruption which had an explosive component at an early stage. Nabro has seen such fissure activity before, and perhaps not that long ago (in geological terms), but with so much of this remote and little-studied volcano’s history and character being unknown it’s difficult to state anything for certain.

The latest volcanic ash advisory from Toulouse VAAC, issued at 06:00 UTC, reports ‘continuous emission’ from the volcano with ash at between FL200 (20,000 feet/6000 metres altitude) in the vicinity of the eruption to FL450 (45,000 feet/13,700 metres altitude), predicted to reach at its extremes as far west as Chad and as far north as Uzbekistan by this afternoon.
