A close up view frown Professor Shawn Willsey's livestream showing just how close the southern fissure is to town. This was taken a few hours ago via ariel drone. The vent opened in real time while the drone was flying and observing the northern rift.
A few hours later, a structure in northern Grindavik closest to the southern fissure appears to have caught on fire.
If there is any good news to be found, the eruption appears to have lost a bit of its initial thunder.
