An ice surge at Jökulsá á Fjöllum - 20.1.2015

An ice surge is occurring on Jökulsá á Fjöllum at Grímsstaðir. The ice that had formed on the banks and the surface of the river has broken into many fragments, creating an icy, slow moving mixture. Water is beginning to seep over the main road, west of the bridge.

In addition to this news article, see a photo gallery from the bridge and aerial photos from a surveillance flight 21 January.

As the break-up of snow and ice continues, it is possible that water could continue to leak across the road. If the discharge of Jökulsá á Fjöllum increases due to snow-melt or rainfall, then the level of flooding could be greater.

Monitoring device rescued from the lava - 13.1.2015

One of IMO's SO2 monitoring devices, which had been trapped by the Holuhraun lava flow since last year, was rescued on Saturday 10 January by staff from the Institute of Earth Sciences and Reykjavik Helicopters.

This instrument is part of the FutureVolc collaboration with IMO's partners at Chalmers University of Technology and the University of Applied Sciences in Dusseldorf.

Warning banners removed - 31.12.2014

With enhanced SO2 monitoring capabilities and regular dispersal forecasts IMO has decided to remove the yellow warning ribbon from the header of IMO's web.

The gas dispersal forecasts will still be available and monitoring of the SO2 release and dispersal will not decrease. The warning ribbon will be used if the values of SO2 are forecasted or measured to exceed the public safety limits for longer periods of time.

IMO has also decided to remove the warning for an eruption in Holuhraun, as there have not been any significant changes. The eruption is still as closely monitored as ever. Should there be any significant changes new warnings will be issued.

Festive forecast - 30.12.2014

Fine weather is forecast on New Year's Eve and New Year‘s Day in all of Iceland.

Tomorrow morning, winds will be southerly in most of the country, 8-13 m/s with sleet or intermittent rain, but in the afternoon lighter winds are forecast in northern and eastern Iceland with brighter skies.

At midnight, winds will be calm everywhere although light snow showers are expected in the south and the west. Temperatures will be close to zero.

New Year‘s Day has also a fine weather forecast; slow wind, scattered hail and 0°C. Some snow is, however, expected at the northern coast part of the day.

Snow avalanche stopped by a catching dam - 19.12.2014

A snow avalanche released from the mountain slope above the village of Siglufjörður in N-Iceland was stopped by a protective dam, most likely on 12 December.

The avalanche started in a gully below a shelf in the middle of the mountainside at approximately 340 m a.s.l.

The avalanche hit the dam along a more than 50 m distance and left rocks and branches that it picked up on its way on the damside. It was approximately 2 m short of reaching the top of the dam and threw some snow clods over the dam crown.

It is likely that the avalanche would have reached close to or hit the uppermost houses if it had not been stopped by the dam.

The segmented dyke intrusion explained - 15.12.2014

Advanced online publication in Nature reports research by an international team of geoscientists on the formation of the intrusive dyke which extends 45 km in the subsurface from the Bárðarbunga central volcano to the eruptive site in Holuhraun. There, the eruption has been ongoing for more than 100 days.

The paper in Nature reports how the dyke formed mostly over two weeks prior to the onset of main eruptive activity. A model for the dyke also explains unusual and varying direction of dyke segments, that relate to interaction of topography and stresses in the ground caused by divergent plate movements in Iceland.

The team includes 37 scientists from the University of Iceland, the Icelandic Meteorological Office and eight universities in other countries. This is part of the research project FUTUREVOLC funded by the European Union.

Bárðarbunga events

Bárðarbunga - update

The eruption is ongoing although the flux of lava has decreased. The lava field (now well over 84 km²) continues to grow.

The average thickness was 10 - 14 m (max 40 m) in late december. New measurements 21st January show considerable thickening of the lava and the volume is now estimated at 1.4 km³.

The subsidence of the caldera is 61 m and continues but the rate is decreasing. The volume of the subsidence is 1.7 - 1.8 km³.

Gas emissions at the eruption site are life threatening, gas masks and gas meters are required. Very high values were measured at the eruptive site recently, 84,000 µg/m³. Local wind anomalies can occur due to thermal convection from the lava. Conditions on site are extremely dangerous as winds can change suddenly and unpredictably. Dispersed, the gas can be detected anywhere, see text forecast and an automatic forecast.
