A statement by the Icelandic Meteorological office has been released:
"An eruption has begun. The source is southeast of Litla-Skógfell. It is in a similar area to the crater that was most active during the eruption in August.
"At this point in time, seismic activity has been highest in the area from Litla-Skógfell in the north to Sundhnúk in the south.
"Based on the seismic activity, the magma tunnel that has formed is 6.5 km long. For comparison, the magma tunnel that formed in the last event was about 20 km long.
"Over the past 15 minutes, seismic activity has increased slightly, and some of the tremors are moving closer to the surface. This could be evidence that magma is trying to break through to the surface."
