Mapping and Assessing Surface Morphology of Holocene Lava Field in Krafla (NE Iceland) Using Hyperspectral Remote Sensing
Iceland is well known for its volcanic activity due to its location on the spreading Mid Atlantic Ridge and one of the earth’s hot spot. In the past 1000 years there were about 200 eruptions occurring in Iceland, meaning volcanic eruptions occurred every four to five years, on average. Iceland curre...
