Daily status report 07. September 2014 – compiled by IMO (Icelandic Met Office) and IES (Institute of Earth Sciences)
The eruptive activity at Holuhraun continues at similar intensity.
The seismicity has reduced since yesterday.
The eruption sites are the same as before. Lava flows to the East at similar rates as yesterday. Although the lava is now in contact with the river Jökulsá á Fjöllum, it does not reduce the lava flow rates significantly. N
explosive activity due to the lava and river water interaction has been observed, but steam rises from the lava.
The extent of the lava is now approximately 19 square km. Magma flow is between 100 and 200 m3/s.
No activity is now detected on the southernmost fissure although small amounts of gas and steam are rising from it.
Eruptive activity in the northernmost part of the north-fissure has no more lava fountaining, whereas the central craters are the most active like previous days.
The new fissure in the south shows no visible activity since this afternoon.
The lava tongue now extends 11 km to the north and has reached the western main branch of Jökulsá á Fjöllum river. However, no explosive activity due to the lava and river water interaction has been observed, but steam rises from the lava.
A white eruption cloud rises 3 – 4 km and is directed to the north and northeast.
