Merged/Geo-rectified Maps

Purpose

The Purpose of this Post is to locate the Position of the Eruptions more Precisely by Merging with a base map!

Details

The DMA map(from National Land Survey Iceland), and the 2 Imageries (from Google and NASA) are Merged (Geo-rectified) to locate the fissure and the developments more precisely. The maps are Merged using GIS software with Non-earth coordinates (XY)!

The following snaps are the results.

Purpose

The purpose of this post is to locate the exact position of the Volcanic activity on Google and NASA Maps and identify the fissure from where the eruptions are coming out.

Details

The fissure from where the eruption is currently occuring is oriented NE-SW and is located at N63º38.1, W19º26.4

The base image from where i got the locational reference of Volcanic activity is from Nordic Volcanological Center, Institute of Earth Sciences, University of Iceland.

I tried to locate this position on Google Earth Maps, but in the Google imagery the land is covered with ice and faintly demarking the fissure. As an alternate source i have also choosen an imagery availabe from Aster Volcano Archives, NASA.

Note: there is a change in imagery as we further zoom-in in google maps.

The fissure from where the volcano is erupting can be noted as a dark shade in NE-SW direction.
