Vatnajökull (2110 m) is the largest glacier in Iceland and it’s also the largest glacier mass in Europe. It covers an area of roughly between 8100 sq. km and 8300 sq. km, and it’s about 1000 m thick at its thickest point. Its average thickness is 400 - 500 m, and the total ice volume of Vatnajokull is probably in the vicinity of 3300 cubic km.
Iceland's Met Office or Icelandic Meteorological Office (IMO) is Iceland's national weather service. Currently, IMO is monitoring the ongoing volcanic activity of Bardarbunga volcano.
Iceland's Meteorological Office recorded earthquakes of 5.3 and 5.1 in the early hours of Sunday.
Bárdarbunga is a large central volcano lying underneath Iceland's 500-m thick Vatnajokull glacier in the center of the country. It is located at the junction between the eastern and northern volcanic rift zones in the area where the present-day center of the mantle hot spot beneath Iceland is thought to be.
Iceland is covered by ice, glaciers and geysers and has got more than 20 active volcanoes. The largest volcano is called Vatnajokull and covers 8% of the country. The country lies on two tectonic plates along which the volcanoes are located: the Eurasian and North American plates. The lava which came from the volcanoes on the plate borders formed the island. The last addition of islands to Iceland was formed in 1963. This island is called Surtsey and is located 30km off the main island.
