A state of emergency has been declared in southern Iceland following yet another volcanic eruption on the Reykjanes Peninsula, the fourth since December.

The powerful and fast lava flows started late Saturday, but authorities say they have since subsided significantly.
The activity around the fissure, which was initially 3 kilometers long (1.9 miles), has subsided.
According to Iceland's Meteorological Office, the lava streams continued to flow on Sunday, but their rate of movement had slowed.
The director of Iceland's civil defence, VÃdir Reynisson, said all that could be done to prepare for the flow of lava had been done, and the biggest concern was the impact
Pools of lava gathering near defences were also of concern, he added.
The eruption began after 20:00 local time (20:00 GMT) on Saturday, north of Grindavik, according to the country's civil defence service,
This is a similar location to the eruption that began on 8 December.
Footage of the explosion showed clouds of smoke and glowing magma oozing and bubbling from vents in the earth.
The explosion has not affected the main international airport, which lies to the north-west of Grindavik.
