Erta Ale volcano Nov 2010: overflowing lava lake

VolcanoDiscovery stayed on Erta Ale between 25 and 28 November. We were surprised to find the south crater filled with fresh flows, and the lava lake overflowing onto the caldera. The following photos, arranged in chronological order, give an impression of the activity and the changes of the lava lake in the south crater.
A first view of the south crater on 25 Nov 2010, from the western caldera wall. The crater is largely filled with overflows from the lava lake, and the lower northern rim of the crater has diappeared under overflows. (Photo: Tom Pfeiffer)

The lava in the lake has risen and is violently boiling. In intervals of about 20-30 minutes, the level of the lava periodically rises and falls, corresponding to periods of stronger and weaker degassing. (Photo: Tom Pfeiffer)

The ring wall is constantly being built higher, as fountains throw lava up, some of which lands on the wall. (Photo: Tom Pfeiffer)

On 25 Nov, the lava level often rises to the rim of the ring wall, then descends again. Large spectacular bubbles burst. Note the intense heat blur and the formation of Pele's hair. (Photo: Tom Pfeiffer)
