Sharp increase in harmonic tremors in Grímsfjall volcano

Something is happening at Grímsfjall volcano. The SIL seismomter on Grímsfjall volcano is shows a sharp increase in harmonic tremors in Grímsfjall volcano. It also appears that earthquake activity in increasing in Grímsfjall volcano.

I do believe (based on the data so far) that a eruption is about to start in Grímsfjall volcano. I am going to post more updates on this when I know more. But please note that I might be wrong. But this is what the data suggests so far.

    How can you tell if they’re harmonic from that display? With all the ups and downs and spikes I find it hard to see a pattern over such a short time.

  3. A new blog post is up about this.
