Kverkfjöll

Kverkfjoll

Stratovolkan · Iceland · 1930 m

Kverkfjöll, seen here from the north, is a subglacial volcano at the northern end of the Vatnajökull icecap, west of Bárdarbunga. The Dyngjujökull glacier, an outflow sheet of the Vatnajökull icecap, appears in the foreground during a 1977 glacial surge. The dark ridge on the left, seen here separated from the outflow sheet by a stream, is a lava flow from about 4,500 to 6,100 years ago.

Ringkasan geologi

Kverkfjöll is a large subglacial volcano at the NE end of the Vatnajökull icecap. Two elliptical ice-filled calderas, each about 8 x 5 km in size, have been identified. An associated fissure swarm can be traced 60 km to the NE. A half dozen ridges of subglacially erupted pillow lavas are now exposed and extend beyond the glacial icecap to the NE. Subglacial historical eruptions have been recorded since the mid-17th century. Several other historical eruptions once attributed to Kverkfjöll are now thought to have originated from Bárdarbunga volcano to the west.

Ringkasan Wikipedia

Pegunungan Kverkfjöll terletak di perbatasan timur laut gletser Vatnajökull di Islandia. Gletser Kverkjökull [ˈkʰvɛr̥kˌjœːkʏtl̥] dapat ditemukan di antara Vatnajökull dan Dyngjufjöll. Gunung-gunung tersebut hingga kini merupakan gunung berapi aktif. Mereka sering meletus dan menyebabkan gletser mengalir, dan tercatat paling aktif pada tahun 1720-an.
