The situation was reviewed this morning by scientists from IMO, the University of Iceland and the Civil Protection System of the Icelandic police. Scientists are now on the way to Askja to evaluate the impact of the rockslide and any remaining hazards. Traffic in the area is restricted until further notice. The responsible

of 3–4 calderas. The youngest one hosts Lake Öskjuvatn and was formed over a period of 30 years after an eruption in 1875. Before that, Öskjuvatn did not exist and, therefore, the rims of the caldera are geologically a very young area. Such slopes are more unstable than slopes in older landscape. It is clear from geological evidence that rockslides similar to the one that fell in July 2014 have been

off in the event of an earthquake. The effects of an earthquake on the
Reykjanes Peninsula, can be felt in a large area, and the capital area is not
excluded.The Scientific Advisory Board, therefore, encourages
people to check with their home and workplaces and fix unstable hanging
objects. Information on earthquake

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.
