Covering an area of 8,492 km2[1] (including Vegafonna ice cap) it is the largest ice cap by area and with 1,900 km3{{cn|date=March 2019}} (excluding Vegafonna) the second largest by volume in Europe, after the Vatnajökull in Iceland (not counting the still larger Severny Island ice cap of Novaya Zemlya, Russia, which is located in the extreme northeast of Europe).[2] Austfonna has a thickness of up to 560 metres (235 meters average thickness), and is 200 km in circumference. The ice dome reaches an elevation of 783 meters above sea level.{{cn|date=March 2019}} The southern third of Austfonna is sometimes called Sørfonna, which is a separate ice cap, separated from the main part of Austfonna by a long, ice-filled depression, and forming a separate crestal dome.[3] Vegafonna ice cap in the southwest is also connected to Austfonna proper, specifically to Sørfonna, and is separated from it by Erica Valley.[3] Vegafonna also forms a separate dome. Immediately west of Vegafonna is Glittne ice cap,[3] which is considered part of the former.{{cn|date=March 2019}} Vestfonna in the northwest of the island is a totally separate ice cap (the third largest of Svalbard and Norway).{{cn|date=March 2019}} See also
