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.

What is Bárðarbunga? - 10.12.2014

There are about 30 known central volcanoes, or volcanic systems, in Iceland. Bárðarbunga, the second highest mountain of Iceland. A caldera in the volcano's crown is covered with approximately 850 m thick glacial ice. Eruptions can occur in the caldera, on the sides or in the fissure swarms. Because of the current seismic activity in nortwestern Vatnajökull, IMO has been allowed to publish the chapter Bárðarbunga System, an extract from a much larger work in progress.

Gale force wind in Westfjords - 9.12.2014

Very high northeasterly winds (25-35 m/s) are forecasted in the northern Westfjords this afternoon, 9 December.

At Hornstrandir and by Ísafjarðardjúp, including habited areas, the weather will worsen considerably between 2 – 3 PM with these high winds and snow.

This evening and tonight northeasterly winds 20-28 m/s are forecasted with snow and hail in all the Westfjords. Tomorrow morning, 10 December, winds will calm down.

Warning - high tides in the Westfjords - 8.12.2014

High seas are expected off the shores of the Westfjords on Tuesday evening 9 Dec. and Wednesday morning (10 Dec.).

Because of the tide, a warning is issued; waves and surf on the relevant coasts might become unsually strong. Waves over 12 m from the north and northeast are forecasted.

Warning for Sunday and Monday - 28.11.2014

IMO draws attention to the weather forecast of strong or whole gale for this coming Sunday and Monday. Flooding may occur.

Westerly and southwesterly winds, 20-30 m/s, can be expected; in the southern part of Iceland on Sunday evening but in the northern part early on Monday morning. Cooler air will follow the westerly winds, with precipitation changing from rain to snow showers at sea level. Average wind speeds may be expected to exceed 28 m/s, which is whole gale according to the Beaufort wind scale. Wind gusts can be exptected to reach 50 m/s, especially to the north and east of mountains (the leeside). This results in very poor traveling conditions.

A warning due to flooding has also been issued. There will be heavy rain and fording rivers may become dangerous in certain areas.

Bárðarbunga events

Bárðarbunga 2014 - updated information

The lava field (now 80 km²) continues to grow and the empty central patch has now been filled. The subsidence of the caldera is over 56 m and continues but the rate has decreased. The volume of the subsidence is at least 1.7 km³.

On the occasion of 100 days of eruption some new interesting facts are given: Comparison with the historic events Laki 1784-1784 (Skaftáreldar) and Eldgjá 934. A map which shows the progressive expansion of the new lava. Earthquakes, GPS and Gas release.

It is estimated that the eruption produces 35,000 tons SO2 daily. Gas emissions at the eruption site are life threatening, gas masks and gas meters are required. There, 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.
