Pyroclastic flows descended the western and southwestern flanks into the sectors of Mapayacu, Yuibug and Choglontus.
The eruption produced loud cannon-shot and rumbling noises that were heard at far distance; the Geophysical Institute notes that many people in the NE provinces of Ecuador even thought that these sounds came from (also active) Reventador volcano which is nearer. [less]

At least 3 people were killed in the eruption, two villagers and a journalist who tried to approach the crater and was hit by bombs. According to newspapers, at least 9 children are missing, more than 20 people injured and thousands fled their homes or were evacuated. Many buildings were damaged.
Authorities evacuated the National Park of Pacaya and nearby villages and declared the state of emergency for the region. The significant ash fall caused traffic chaos in Guatemala city and the international airport to be closed. [less]

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. [less]

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]
