Which country is home to Europe's largest glacier by volume?

Vatnajökull also known as the Vatna Glacier in English, is the largest and most voluminous ice cap in Iceland, and one of the largest in area in Europe. It is the second largest glacier in area after Austfonna on Svalbard in Norway but, nevertheless, larger by volume. It is located in the south-east of the island, covering more than 8 percent of the country.

The name Vatnajökull is derived from vatna, the genitive plural form of vatn which means "water" in Icelandic but is also used to refer to a lake, and jökull, the Icelandic for glacier.

With an area of 8,100 km², Vatnajökull is the largest ice cap in Europe by volume (3,100 km³) and the second-largest (after Austfonna on Nordaustlandet, Svalbard, Norway) in area. On 7 June 2008, it became a part of the Vatnajökull National Park.
