Hi all

Hi Roger

There was an earthquake warm last night and it did last until 11:37 (i
think there where about ~200 earthquakes that did happen in this
earthquake swarm), the earthquakes that i did record where all in poor
qualiti. I think that might come from the depth that they where
happening on, but also how they where breaking up in the crust. 

Today i did change my setup a little bit, i did increase the gain and
did set the sps to 50, this move was based on a advice that i got
earlyar today. That is also the reasion why my online graphs are so

Now i just have to wait for a earthquake to see how good or bad change
it was that i did do today. I don't think that i am going to have to
wait for a long time before i record a earthquake at this new settings.
I already know that i was able to detect earthquakes down to ~2.4Ml at
the range of ~200km max, if the earthquake had good recording on the
Icelandic Met office seismic network.
