In the Reykjanes Peninsula, the eruption continues; The flow in the main channel was measured from video at a flow speed of 7.7 m./s., or 28 km / h.
The photos taken on April 7 show that the new (central) fissure emits on both sides, and in the process swallowed the webcam, and that the lava fields have merged : a continuous lava field and three eruptive sites, which belong to the to the same eruptive fissure. This extends from Natthaga north-east to Kellir, above the magma corridor drawn since February.
