The eruption area at Holuhraun remains closed due to significant unrest in the underground dike north of Dyngjujökull, which was measured yesterday afternoon.

There are still no signs of a sub-glacial eruption, which would cause a flood, but one possible explanation for the unrest is that the magma has come into contact with water through underground fissure systems.

RÚV’s reporter Lára Ómarsdóttir flew over the area and observed that not only have rifts formed in the ground but also troughs, in which the ground has sunk visibly. This can be seen in the accompanying video.

The number of earthquakes has declined slightly, even though yesterday over 400 quakes shook the ground. The main concern is that the current volcanic eruption fissure might extend under the glacier.

The Icelandic Met Office says that no obvious changes, such as increased water flow or cauldrons on the glacier's surface were observed from scientists onboard Coast Guard airplane TF-SIF this afternoon.

Water meters in glacial river Jökulsá á Fjöllum do not show any unusual changes in discharge and electric conductivity. The low frequent tremor signal is still continuing, its strength is variable.

Iceland Review's team was at the eruption site yesterday but had to leave when the order came to evacuate the area.
