Hi all

My new station at Borgarnes is close enugh to record earthquakes from
the Myrdalsjokull Volcano
(http://www.volcano.si.edu/world/volcano.cfm?vnum=3D1702-03=3D).

I have already recored few earthquakes from that volcano. But most of
them are small, from mag 1.5 to 2.2 on the ricther scale. But most of
those earthquakes have strange carticstics that I have known about for
years, but never been able to understand or see before. Most of thease
earthquakes have frequancy that goes down to 1Hz and lower. Based on the
poor recordings I currently got, there appears to be small tremor noise
(magma moving?) following the earthquakes. But because how the poor
current recordings are, that is unconfirmed at the moment.

Any suggestions on what I am looking at are welcomed. Since I am unsure
what is going on in the Myrdalsjokull (Katla) Volcano. But it is known
that the Myrdalsjokull Volcano has been warming up for a long time now
and is ready to blow at any time.

Regards.
