dc.description.abstract |
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 currently has 30 active volcano systems, distributed evenly throughout the socalled
Neovolcanic Zone. One of these volcanic systems is the Krafla central volcano, which is
located in the northern Iceland at latitude 65°42'53'' N and longitude 16°43'40'' W. Krafla has
produced two volcanic events in historic times: 1724-1729 (Myvatn Fires) and 1975-1984 (Krafla
Fires). The Krafla Fires began in December 1975 and lasted until September 1984. This event
covered about 36-km2
surrounding area with lava, having a total volume of 0.25-0.3 km3
. Previous
studies of lava surface morphology at Krafla focused on an open channel area by remote sensing
are essential as a complementary tool to the previous investigations and to extend the area of
mapping. Using Spectral Angle Mapper (SAM) classification approach by selecting spectral
reflectance end members, this study has successfully produced a detailed map of the surface
morphology in Krafla lava field EO-1 Hyperion (Hyperspectral) satellite images. The overall
accuracy of lava morphology map is 61.33% (EO-1 Hyperion). These results show that
hyperspectral remote sensing is an acceptable alternative to field mapping and assessing the lava
surface morphology in the Krafla lava field. In order to get validation of the satellite image’s
spectral reflectance, in-situ measurements of the lava field’s spectral reflectance using ASD
FieldSpec3 is essential. |
