The Icelandic Meteorological Office (IMO) has decided to move the aviation color-code from red to orange as observations show that a sub-glacial eruption in Dyngjujökull outlet did not occur yesterday, contrary to what scientists at the IMO thought. However earthquake activity connected to the Bárðarbunga volcanic system in NW-Vatnajökull remains very strong, with 700 earthquakes beeing detected since midnight and being somewhat larger than previous days. A magnitude 5.3 earthquake struck at Bárðabunga at 00.09 this night, the largest eathquake within the caldera so far, and at another large earthquake of magnitude about 5 occurred at at 05.33.
According to IMO the intense low-frequency seismic signal observed yesterday belived to signaling a sub-glacial eruption has other explanations.
IMO reports that activity under Dyngjujökull, which is a part of the Bárðarbunga volcanic system, has propagated northwards and is now mostly under the edge of the glacier.
The dyke under Dyngjujökull is now estimated to be approximately 30 km long.
