The above footage was taken by RÚV cameraman Þór Ægisson yesterday.
The volcano is currently erupting from eight fissure vents along a roughly-one-kilometre-long line, though it can be sometimes difficult to define and distinguish individual vents as they multiply and the lava field expands.
Björn Oddsson, geophysicist with civil protection agency, flew over the volcano in a coastguard helicopter yesterday and confirmed that four new lava flows did indeed form earlier that morning. The RÚV drone footage also shows the new vents.
Björn says the two new vents nearest to the original ones are very close together and could potentially merge with time. He says there were eight distinct eruption centres when he flew over.
University of Iceland monitoring shows the lava field is now an average of 14 metres thick. The eruption will be four weeks old this Friday and shows no sign of coming to an end.
