The ASTER sensor captured the thermal signals from the fissure activity at 12:32 UTC, today, September 16, 2014. The data was from the Bands 3N, 2 and 1, so at 0.8, 0.66 and 0.55 microns respectively. Below is an RGB of these channels overlayed in Google Earth.

Examining the hottest portion of the region, likely the active fissure, this is 630 m long. There are two other points that show significant thermal signatures. Seem zoomed in view below. These are 400 m approx from the fissure, 160 m apart.

Displaying the 3N channel, 0.8 microns, only, we are able to see the portion that is the most thermal active. We can enhance the 3N data to see the full flow off to the northeast of the most active feature,

For more information on the real-time activity, see the Icelandic Met. Office [http://en.vedur.is/] and for a volcanic ash advisories see the London VAAC [http://www.metoffice.gov.uk/aviation/vaac/].
This is my interpretation of the ASTER data. Thanks to the NASA LP DAAC for access to this data.
