days. A volcanic crater has formed in the south-western corner of the cauldron. Erupted material from the vent continues to accumulate on the flanks of the crater. The rim of the volcanic crater is ~50 m lower than the surrounding ice cauldron. Volcanic spatter was observed from the vent, with ejected lava reaching heights of 100-200 m.
Unstable plumes of ash rise regularly from the vent.

of the slide is concave. The volume of the slide is roughly estimated 30–50 million m³, however, the estimation may change when further measurements and analyses have been carried out, especially on the part that is in the lake and regarding the depth of the sliding surface. If the bottom of the slide reaches below the lake bottom, the total volume of material that moved may be a lot more

the first scientific treatise on the subject in 1796 (Finnsson, 1796). The great naturalist and geologist Þorvaldur Thoroddsen collected documentary material into a volume on the climate history of Iceland in 1916 (Thoroddsen, 1916) and later Jón Eyþórsson, Sigurður Þórarinsson and Páll Bergþórsson wrote papers on the subject (see references).

needs to be based on an understanding of the dynamics of granular flows against obstructions that lead to a change in the flow direction, slow the flow down or cause it to stop. Laboratory experiments have been performed in recent years with granular material in order to shed light on the dynamics of avalanche flow over and around braking mounds and catching dams and to estimate the retarding effect

Increased usage of IMO's web-site
The graphs below (from Webalizer) show the usage of IMO's web-site every month from January 2010 into April 2011 (fifteen months later). Due to the eruption, the spring 2010 was exceptional.
