A video published on the BGS YouTube channel shows a timelapse of glacier flow over the icefall between the 11th of April 2011 and the 22nd of April 2012. A single image from 12 o'clock each day has been used. The ash from the Grimsötn Eruption can be seen at around 14 seconds onwards. Grimsvötn itself sits within the western portion of Vatnajökull, only 50km northwest of the Virkisjokull Observatory. The tremendous power of glaciers as agents of landscape change can be understood when one sees the speed at which ice is able to flow. Their ability to shape and carve modern mountain chains can be seen all over the world, and their legacy spreads far wider, into landscapes now totally devoid of permanent ice , both upland and lowland.
