The enormous rockslide that fell from the eastern caldera rim of Askja volcano, central highlands, on July 21st was the largest one to date, reports the Icelandic Broadcasting Service.
Ármann Höskuldsson, a volcanologist with the Institution of Earth Sciences at the National University, expects more landslides will fall from the caldera come winter. The water level in Öskjuvatn lake rose by about 2 metres (6.5 feet) after the massive landslide in July.
According to Ármann the caldera, which was formed during an eruption in 1875, is still in formation. “Askja’s southern rim is clearly very unstable, meaning more rockslides will fall this winter and next spring.” He adds: “These landslides will probably be smaller than the one that fell in July.”
