Þorlákur Sverrisson kaupmaður í Vík í Mýrdal tók ljósmyndir af Kötlugosinu 1918 „frá byrjun til enda“ svo vitnað sé í hans eigin orð. Raunvísindastofnun fékk 18 glerplötur að gjöf frá erfingjum hans og eftirmyndir af 17 þei

Eruptions where glacier ice has a significant effect on the style of activity occur in some parts of the world, notably the Andes, Alaska, parts of Antarctica and Iceland. Due to its northerly latitude and considerable ice cover within the volcanical

Due to poor preservation and lack of proximal tephra thickness data, no comprehensive isopach map has existed for the tephra layer from the major eruption of the Katla volcano in 1918. We present such a map obtained by combining existing data on the

Grain size and shape analyses were performed on silicic to intermediate Katla tephra (SILK) formed 2800–8100 years ago to examine whether the grain characteristics had changed with time, and in such a case, could they reflect changes in the eruptio

Activity of the Katla volcano, under the Mýrdalsjökull ice cap, is characterized by explosive basaltic eruptions and occasional silicic eruptions. Tephrochronology indicates that it has erupted over 300 times during the last ∼8400 years. About 40

Tephra is the ideal volcanic product for the study of eruption history of Icelandic volcanoes and the underlying magmatic processes. In the last 11 centuries, 2/3 of all eruptions have been explosive, leaving tephra as their only product. Including e

Currently the Late-glacial and Holocene marine tephrochronology on the shelf around Iceland comprises 130 tephra layers from 30 sediment cores ranging in age from 15,000 years cal. BP to AD 1947. A vast majority of the cores and tephra layers are fro
