Yesterday it was raining a quite lot. But everything looks fine at this

water is down. The real test comes when the snow arrives and leaves.
Noise levels are good, better then I did expect, but I haven't seen
everything yet. So I don't know how this looks in the long term.
Sensitivite appears to be good, if I can use the local noise a guide.
There hasn't been a earthquake that I can use to check, yet anyway. It
has started to freeze agen, so I might see frostearthquakes soon, small
spikes that happen when the ground freezes, the geologist at Icelandic
Met office told me about them, I am going to look out for them when
I didn't seal the geophone where the cable comes out, if water gets in I
don't think that anything is going to stop it anyway from reaching the
internals of the geophone. I also expect to see it farly quickly if that
