Erta Ale Vulkan Nov 2010: überlaufender Lavasee

VolcanoDiscovery war vom 25.-28. November 2010 am Erta Ale. Wir staunten nicht schecht, den Südkrater mit frischer Lava gefüllt zu finden und den Lavasee regelmäßig beim Überkochen zu erleben... Die folgenden Fotos in chronologischer Reihenfolge sollen einen Eindruck von der Tätigkeit und den Veränderungen des Lavasees geben.

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)

View of our old favourite observation spot on the S rim near the spot where the rim has been flooded. The lava has risen 20 m since last November and is now at the same level, but mostly hidden behind the ring wall. A better view is from the cone south of the crater. (Photo: Tom Pfeiffer)

While the lava inside the ring wall is hidden from the northern rim, it is barely visible from the little cinder cone south of the crater. View is to the north across the south crater. (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)

Sometimes, large quantities of lava are thrown outside the wall creating small secondary flows. Bursting lava bubbles are torn into thin threads, Pele's hair. (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)

Explodierende Lavablasen im Lavasee sind nachts zu grell zum Fotografieren. Die Lava kocht an einer Stelle über und lässte einen kleinen Lavastrom ausfließen. (Photo: Tom Pfeiffer)
