Volcanic activity at Bárðarbunga, Iceland, monitored with TerraSAR-X and TanDEM-X data
The central volcano Bárðarbunga, with a 65 km² large caldera, is located on the northwestern edge of Vatnajökull ice cap. It is connected with a 190 km long, from southwest to northeast running fissure system within the Neovolcanic Zone of Iceland. The subglacial volcano reaches a height of 2009 m a...
