Description

Abstracted geological map of subglacial features under Vatnajökull glacier for use in articles on 1996 eruption of Gjálp, Grímsvötn, Bárðarbunga, Trölladyngja, Loki-Fögrufjöll, Tungnafellsjökull and Kverkfjöll. Lava fields for Bárðarbunga, Trölladyngja, Holuhraun, Þjórsá Lava and 2014–2015 eruption of Bárðarbunga articles.

Source

The data and its representation is original. It has been checked against other mapping representations/abstractions. Please refer to original sources for more accurate mapping. Seismic data for this area before 1995 had poor location information but data between 1975 and 1985 has also been examined as part of validation of areas of seismic activity and thus possible magma bodies:

Additional information The data has switching logic. It is no longer a pure json file. Json to be added is best debugged else where. The map is complimentary to data files Wikipedia:Map data/Katla Wikipedia:Map data/Askja, Wikipedia:Map data/Hofsjökull, Wikipedia:Map data/Öræfi volcanic belt, Wikipedia:Map data/Snæfellsnes volcanic belt, Wikipedia:Map data/Hengill and intended data file Wikipedia:Map data/Vatnajökull which may abstract out glacial data. There is purple/violet shading for some lava fields that are only shown in specific maps. The following default shading scheme applies:   calderas, other   central volcanoes,   fissure swarms or   fissure swarms over green shading,   subglacial terrain above 1,100 m (3,600 ft),   seismically active areas between 1995 and 2007.
