Tungnafellsjökull

Tungnafellsjokull

Estratovolcán · Iceland · 1523 m

The Tungnafellsjökull central volcano lies immediately to the NW of the massive Vatnajökull icecap. The ~ 4 x 9 km summit caldera is largely filled by the Tungnafellsjökull glacier (center). An ice-free caldera to the SE, Vonarskarð, measures about 8 km in diameter; the caldera rim is visible in this image as a ridge at top left.

Resumen geológico

The Tungnafellsjökull central volcano, located immediately NW of the massive Vatnajökull icecap, contains two calderas. One is largely filled by the Tungnafellsjökull glacier, and the other ice-free caldera located to the SE contains Pleistocene rhyolitic lavas. The volcano is largely of Pleistocene age, but postglacial flank fissures on the NE side have produced young basalts. The Hágöngur central volcano to the SW is part of this volcanic system.
