The ash cloud has spread over much of England, including London, as well as other parts of northern Europe and caused the cancellation of ca. 1,000 flights over Europe. The ash cloud blanketed a good swath of Iceland Monday and covered the area to the south over the Faeroe Islands as well as northern Scotland. Ash is also covering Northern Ireland and south-central England, including London. [less]

New (hopefully localized) disruption of air traffic in the next days is quite likely. [less]

The Icelandic Met Office reports: "The crater is getting higher. Lava flow is low and not visible on cameras. In the afternoon there was a slight increase in explosive activity, which resulted in a higher plume for a while.
Seismic tremor has been similar for the past 3 days. A sequence of earthquakes started around 11:00 this morning at depths of 18 - 20 km and magnitude range 1 - 2. The earthquake sequence this morning indicates that magma is still flowing in from the mantle. Presently there are no indications that the eruption is about to end." [less]

The ash cloud from the strong phase of 3-4 days ago when plume heights reached near 10 km again is presently still roaming through Europe and causing airports to close down. After Spain and Portugal, northern Italy, then southern Germany, parts of Austria and the Czech Republik had been forced to shut parts of their airspace and airports down, cancelling hundreds of flights until Sunday evening, most airports are reopening this Monday.

19 airports in Span and Portugal were partially closed today because of the ash plume from the past days. [less]

The explosive activity has increased and effusive activity has decreased during the last two days, resulting in a a higher eruption column to up to 9km (30,000 ft) with increased tephra fallout around the volcano, which is now almost completely black.
Considerable ashfall occurs at Þykkvabæjarklaustur in Álftaver (at a distance of 65-70 km). [less]

At the volcano, lava continues to flow from the summit crater and has advanced over 3 km on the north slope of Eyjafjallajökull.
There are no indications that Katla volcano is going to erupt as well. [less]

Flight operations in the European airspace (which in an unprecedented case had been largely closed for 5 consecutive days due to the presence of ash from the eruption) are almost back to normal and slowly, the long queue of stranded passengers around the world are returning to their destination. In the meanwhile the debate about wether European air control authorities and decision makers have been too strict in their measures and "responsible" for the huge (estimated between 1.5-2 billion eur) loss for the airline industry is going on hot.
For a well-balanced discussion, we recommend the following article on Erik Klemetti's excellent Eruptions Blog. [less]

New photos from the ongoing eruption have been posted.
As the ash emission is now low and the original high ash cloud is dispersing, flights through the European airspace are gradually resuming, to the relief of tens of thousands travellers stranded throughout the world. [less]

Tens of thousands of planes - most planes to and within Europe - have been cancelled, causing unprecedented chaos for people travelling all over.
In the meanwhile, we are proud to present a set of new photos of the ash cloud on the glacier taken by our new team member Jorge Santos who is currently at the eruption site. [less]
