Geldingadalur, Fagradalsfjall Volcanic Eruption

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.
