areaA fracture was
formed in the upper part of the mountainside NE of the crown of the landslide
release area in connection with the slide. This fracture needs to be monitored
for a while because of the danger of further slides. For the time being, it is
not considered likely that another large landslide will be released from the
mountainside. Rocks and small slides are, however, frequently

in northwestern Vatnajökull ice cap and therefore covered with ice.
The enormous size and nature of Bárðarbunga was not fully recognized until it was observed in 1973 on an image from a satellite, 800 km above Earth (see below). A caldera in the volcano's crown, 11 km long on the longer side, is covered with approximately 850 m thick glacial ice. Eruptions related to the central volcano can occur
