Description

Abstracted geological map of Öræfi volcanic belt initially for use in articles on Öræfajökull, Esjufjöll, and Snæfell. It has also been used in articles Geological deformation of Iceland, Thordarhyrna, Bárðarbunga, Grímsvötn, Loki-Fögrufjöll and Kverkfjöll as will provide default geological mapping for those that use mouse over functionality.

The data is original, as a compromise representation, and for volcanic features based upon the 2009 work by Haukur Jóhannesson and Kristján Sæmundsson updated in relevant region by Magnússon et al. 2012 and checked against other mapping representations/abstractions:

Representations of the Öræfi volcanic belt exist that map by geological age, palaeomagnetism and other criteria. They should be consulted by those who wish to improve this mapping or resolve the inconsistencies as to boundaries and location of the various systems found in the literature during preparation of this work.

Additional information The data has switching logic that with some maps it is used on eliminates glacier cover display in default mapping, an area where Iceland generally needs better mapping, but also so as to show central volcano outlined in red in relevant article. The map is complimentary to data files Wikipedia:Map data/Grímsvötn, Wikipedia:Map data/Hofsjökull, Wikipedia:Map data/Katla, Wikipedia:Map data/Hengill, Wikipedia:Map data/Askja and Wikipedia:Map data/Snæfellsnes volcanic belt. It is no longer be a pure json file. Json to be added in is best debugged else where what ever. The volcanic system of Esjufjöll is particularly poorly defined but this applies also to other parts of the belt under ice cover. Presently academic sources agree there are 3 main volcanic systems. The main glaciers that may produce jökulhlaups are outlined in white. Glacier data may be transferred in due course to an intended data file Wikipedia:Map data/Vatnajökull. Other shading shows:    calderas,   central volcanoes and   fissure swarms,   subglacial terrain above 1,100 m (3,600 ft), and   seismically active areas. Clicking on the image enlarges to full window and enables mouse-over with more detail.. Clicking on the map enables mouse over that displays such information stored in this data.
