Erta Ale (Danakil depression, Ethiopia): (12 Oct) Our Ethiopian expedition organiser Enku made a reconnaissance trip to Erta Ale in September and reported the current status of this continuously changing active volcano. It appears that over summer the lava lake in the summit crater slowly rose and remains very active, but that the fissure eruption at the volcano’s south flank (which started during the dramatic change of volcanic activity mid January 2017) slowed down.
The lava lake of Erta Ale’s summit caldera is currently at some 75 m below the rim of the south crater, a large circular pit with dimensions of about 230 by 230 m. The lava lake is thereby occupying the northern part of this active crater and strongly degassing, making daytime observations more difficult. However, from sunset throughout the night-time the volcanic gasses periodically clear up so that one can have a clear view onto surface of the active lava lake and observe its constant movement. The thin black surface of the lava lake thereby shows red-hot cracks where liquid lava wells up, pushing the crust sideways and even overflowing and recycling it. Sometimes gasses well up in the liquid lava below the surface and break through it, exploding in large bubbles of lava. The movement of the spreading lava lake crust is steady and strong degassing alternated with clearing up of the view occurs in cycles.
