Hi all

Thanks for the comments and suggestions, i am sure that i will learn
this with time. I did go over the final resaults of this earthquake on
the Icelandic met Office homepage and according to that resaults they
only register one earthquake at that exact time, the size of the evenent
was 3.07 M. Here is the final resaults from I.M.O.

I took also few smaller earthquakes that i didn't detect. Those
earthquakes where few seconds before the earthquake that i did detect.

                                           Depth   M     Ml

12 20060110 002641.410 63.93540 -22.11102  6.147  1.32  0.42

The page that has this info is in Icelandic, it is not on there engish web.
Why this earthquake shows two spikes is something i don't understand. 
But that is problay the reasion why IMO automatic system shows two earthquakes.
The p and s wave diffrance is 20.7 sec, when i did put in the final resaults from the Icelandic
met Office.

At this range i seems to be able to detect earthquakes down to 3 on the ricther scale. The area
where this earthquake was, often has earthquakes that are from 3 - 5 on the ricther scale. So i might not have to
wait so long for other earthquake to happen, in order to see the diffrance on earthquakes.
