Holuhraun magma river is flowing inside a closed channel to the eastern edge of the lava field

  • Holuhraun lava field This thermal image was captured January 3rd at 12.33 (12.33 pm). This is a LANDSAT 8 satellite image from NASA & USGS processed by the Volcanolog and Natural Hazard group, Institute of Earth Sciences, University of Iceland.

Insubstantial changes have been in the volcanic eruption in Holuhraun according to the Scientific Advisory Board of the Icelandic Civil Protection. The magma river is now flowing inside a closed channel to the eastern edge of the lava field, about 15 km (9.3 mi) from the crater.

Magma is also running to the north of the lava field much closer to the crater as can be seen in the image above. Keep in mind that this is a thermal image and the colours depicted are not natural.

Although big amount of lava is still surfacing the gas emission is much smaller than it was in the first weeks of the eruption, easing concerns about high sulfur dioxide pollution.

Holuhraun's new lava field now covers around 83 square km (32 sq mi) and is growing slowly.

The Icelandic Met Office (IMO) reports that more than 20 earthquakes have been detected in Bárðarbunga caldera in the last 24 hours. The largest one, M4.3 struck at 23.29 (11.29 pm) yesterday evening. Some smaller earthquakes have been detected in the dyke intrusion and at Tungnafellsjökull, glacier and volcano northwest of Bárðarbunga.
