@RaphaelGrandin I had a hard time figuring out what was visible on this radar image and from what angle.

In fact, if I'm not mistaken, it only shows part of the summit , its southern part. The very visible crack is not the one currently erupting which is located to the NE outside the radar image. But, may be, it was that fissure that fed the lava lake?

The small volcanic cone in the middle of the fissure was there before current eruption.The broad enlighten (white) zone crossing the image from left to right is the steep western caldera wall. LOS on the map roughly outlines the view angle of the radar image.

@RobinLacassin

Yes, these fissures were active only at the beginning of the eruption. Activity has now shifted to the NE rift zone.
