The eruption which lasted only a few hours probably set a record in the ration between public attention (extremely large) versus size (very small).

...29 Aug:
First pictures of the new eruptive fissure, taken from a helicopter of the Icelandic Coast Guard were released. They show a row of spatter cones and small lava flows that were erupted from the fissure, about 900 m long and located 5 km from the northern edge of the Dyngjuköll glacier.
Current webcam images and other sources do not indicate ongoing activity except steaming.
Seismic activity has decreased as a result of the pressure release, however a significant amount of earthquakes is still detected in the magma dike, between the eruption site and south to about 5 km into Dyngjujökull. (IMO)
...29 Aug:
An exclusion zone 1.5 km above and 15 km around the eruption site is in place.
The circumstances around the eruption are somewhat enigmatic. It is interesting to note that the large intrusion, estimated to contain approx. 350 million cu meters of magma on a length of 40 km only produced a tiny fissure eruption (so far, at least).

...29 Aug:
An eruption started in Holuhraun north of Dyngjujökull at around 00:02. Seismic tremor was observed on all seismic stations and the web camera installed in the area by Mila has showed some nice pictures of the eruption. It is a small fissure eruption and at 02:40 AM the activity appears to have decreased. (IMO)
Note: When more information becomes available, it will be posted on our Special Update Page.
Rabaul (Tavurvur) (New Britain, Papua New Guinea): (29 Aug) A large explosive eruption began at Tavurvur volcano (Rabaul caldera) this morning.
The eruption seems to be similar to a paroxysm on Etna.

Poas (Costa Rica): A series of 3 phreatic explosions occurred at the crater lake after 14:45 local time on Wednesday. The eruptions followed a phase of relative calm during the past months and ejected jets of steam and mud to heights of approx. 100-200 m.
