First of all, my condolences to our American friends.  I saw the tragedy as it was happening on TV.  Very horrifying and sicken
ing
to see it play out in real time.

For slightly over the last week there has been a swarm of earthquakes off the British Columbia coast on one of the plate bounda
ries.
Those of you in the Seattle, and maybe the Alaska areas, might be able to pick up the traces on your seismographs.

Do check the map, its very interesting how they are clustered.
