The aviation code for Bárðarbunga remains at orange. The dyke intrusion beneath Dyngjujökull is now thought to be about 40 km in length and is getting ever nearer to the Askja volcano which is now to having earthquakes.
The Bárðarbunga system as of midday has so far experience over 700 quakes including, at 00:16, a magnitude 5.3 earthquake in the caldera. At 02:50 UTC, another similar-sized earthquake (magnitude 5.2) took place in the same region. Yesterday we saw the strongest quake in this swarm so far, a magnitude 5.7; this is the strongest earthquake to hit the region in nearly 20 years.
