Hi all

I am seeing what I think is movement of magma (it is hard to tell at
this moment). I did notice a change in the IMO tremor plots at three
stations now. So far there are no earthquakes because of this magma
movement. But there is a clear change in the tremor plot on 0.5 - 2Hz
range. If that is any indication, it is clear that the magma has not
reached the surfice yet. 

The change in the plot can be seen on Vatsfell tremor plot and
Skrokkalda tremor plot. - Clearest signal. - Signal appears.

This might be false alarm, but only time can tell if that is the case or
not. If magma is riseing, it is only matter of time until earthquake
starts to appear.

I've will keep this updated if anything intresting starts to happen.

Please send questions if you have them.
