After laying quiet for 9 days, harmonic tremors are being detected again indicating the magma is rising in the volcano again. See a live feed showing the graph below. Note: the feed of water flowing is from a glacial outburst event taking place elsewhere in Iceland...different volcanic system.
Here is a still image of the harmonic tremors over time. The quick spike seen on Sept 8th was from a partial crater wall collapse at the surface.

So the eruption has resumed....but with the 9 days of cooling and hardening of lava, it appears the easiest path to the surface is not the higher crater lip, but multiple other locations as seen by the many small geysers of lava in the video.
