Seismicity continues in Bárðarbunga volcano in Vatnajökull glacier. A magnitude 4.4 earthquake hit 11.5 km (7.3 miles) east of the volcano shortly before 2:30 last night and the strongest earthquake recorded there yesterday was magnitude 5.1.
Geothermal heat continues to increase in Bárðarbunga. Scientists on a surveillance flight above the volcano yesterday could clearly see cauldrons that had formed in the glacier on the western and southeastern rim of the caldera, ruv.is reports.
The largest cauldron has deepened by 25 meters (82 feet) in one month. Scientists link this development to the subsidence of the caldera, which now measures 40 meters. The subsidence cannot be detected with the naked eye as the caldera is 8 km wide.
The eruption in Holuhraun, north of Vatnajökull, continues. The lava erupting in a fissure there originates in the Bárðarbunga magma chamber and is channeled to the eruption site via an intrusive dike, which formed underground before the eruption started in August.
The eruption is visible on webcams, including one established by telecommunication company Míla in August.
