The evolution of the effusive eruption at Erta Ale since 29 November shows reduced activity at the northern pit crater and the reactivation in the southern pit crater on 9 December (image: Sentinel-2)
The effusive eruption at the volcano continues at fluctuating intensity.
In the latest update, both craters were supplied by lava flows, mainly the northern one was exposed pretty vigorous spattering from the hornito generating extensive emissions of incandescent, fluid lava, resulting in lava overflows of the crater rim in the north.
However, after several days, the activity in the northern pit crater started to reduce rapidly, at least what satellite images acquired on 4 and 9 December show. The effusive eruption in the northern pit crater seems to be ceased now.
Meanwhile, our expedition leader, geologist and local guide, Enku Mulugeta from VolcanoDiscovery Ethiopia, provided us with updated information from the site about the volcano’s behavior over the past few days, but in the southern pit crater this time.
Increased lava flows are being fed continuously from the hornito, from where bursting spattering produces molten lava fragments, falling to the ground and coalescing, thereby forming lava flows. They continue to advance towards the caldera rim and are about to overflow it soon, as seen in the attached videos.

Two small thermal anomalies in Erta Ale’s S pit crater were identified in satellite images on 15 September. A 20 September image showed small anomalies in both the N and S pit craters, and a possible lava lake in the N pit crater that had mostly been crusted over. A large thermal anomaly in the SE part of the N pit crater was identified in a 25 September image. … Read all
