Eruption Losing Steam

The volcanic eruption that started on 21 May 2011 under Vatnajökull glacier in Iceland is on its last legs.

The Department of Civil Protection has decreased the level of preparedness from 'emergency' to 'danger' following decreased activity from the volcano Grímsvötn.

There is still slight volcanic activity in the crater, and seismic activity has been measured in the area as well. Access within 6 km of the volcano is still forbidden for safety reasons. Little melting occurred during the eruption, and there is not believed to be danger of floods from the caldera.

Clean-up operations following the eruption in Grímsvötn are well under way. Most of the ejected ash fell in an area South and Southeast of the volcano, but locals expect to be able to resume life as usual in a matter of days.

Roads in the area are once a again open for traffic. As a safety measure, several roads had been closed since Sunday.

Scientists believe the eruption has come to an end, although it cannot be declared officially over just yet.

Grímsvötn is arguably the most active volcanic area in Iceland and has erupted five times since 1983. The last eruption was in 2004. In the past, these eruptions have started with great force and then tapered off after 4-5 days, although low-level activity will sometimes continue for weeks and months. Previous eruptions have not led to wide-ranging flight disturbances.
