Hi all

I was speaking to an seismologist at IMO about the "earthquake" that
happen the 25th April around 07:40. He did suggest that it was a Meteoroid
rather then a earthquake, as the event was recored on most seismic
stations in Iceland around the same time. He did suggests that this was an
earthquake, but given the clues it seems unlikely. If this was a
meteoroid, it is mostly likely that it did exploit high up in the
atmosphere. But no explosion has been reported so far, but the area where
this most likely did happen is unpopulated for most part. This was closer
to Greenland then Iceland, it appears.

I did also record this event and the trace can be seen here.

This is a filtered trace at 2Hz (I think, don't remember what I did filter
it on).

It would be nice to get a different opinion on this.
