Understanding Katla
Probabilistic model for eruptions and associated flood events in the Katla caldera, Iceland (1)In this article, Jonas Eliasson and his colleagues take a detailed look into the proporties of the glacial outburst floods associated with Katla's Volcanism. In understanding the fundimental structures of the volcano and the behavior of the jökulhlaups this team of scientists have formulated a probabilistic model for an eruption in general terms which takes into account the time interval between two events. Their model also uses a matrix which will tell them, given the location of an eruption or glacial melt in the caldera, where the water will be exiting and thereby, what watercourse will be hit by the flood. This is very benificial for the populations in that area because there has not been this information available before. Now, when Katla acts up, scientists will be able to predict accurately where the jökulhlaups will hit.

Volcanic Hazards in Iceland (5)
In this article, Magnús T. Gudmundsson and his colleagues discuss the main hazards associated with the Katla volcano. They look at the history of volcanism in Iceland and what is going on presently. The article also goes into detail about major eruptions in recent history, their hazards and statistics. The article gives good explanations of how the major volcanoes in iceland behave, their eruptive history and their unique hazards. Research on the individual volcanoes is very important for Iceland because they are a country that must learn to live in harmony with the island they call home and the more they know about the hazards, the better they can live with them. Volcanic Hazards in Iceland is very educational and could be useful for the scientific and non scientific reader alike.

People living under threat of volcanic hazard in southern Iceland: vulnerability and risk perception (7)In this article, G. Jóhannesdóttir and G. Gísladóttir take a look at residents living in the village of Vik and the farming community of Álftaver in southern Iceland, southeast of Katla Volcano, who are living with the threat of volcanic hazards. The purpose of their research was to review residents' responses in relation to vulnerability, examine their risk perception, preparedness and mitigation in relation to an eruption of Katla, and finally, to investigate the public and the representative of the local authorities and emergency manager's knowledge of the official evacuation plan. The result of this research will be to see how effectiveness of the hazard evacuation plans are and how they can be improved.

Seismic and geodetic insights into magma accumulation at Katla subglacial volcano, Iceland: 1999 to 2005 (11)In this article, Erik Sturkell and his colleagues discuss at the seismic data that preceded a major jökulhlaup in 1999 and analyze how the earth and more spacifically, the volcano, behaved before the jökulhlaup. With this data they discuss what specifically indicates the formation of a jökulhlaup. The knowledge this provides will help in the prewarning system for the jökulhlaups in populated areas and give authorities more time to get everyone to safety.
