QUICK SUMMARY:

Whoa, big earthquake overnight as RyanC notes in his wake-up calls.  Crazy 20hrs with high winds first which then died and tagged in the big EQ!  Seismic motion elevated 8hrs ago for the EQ, and finally calmed down within the last hour.  H1's been locked for the last 2+hrs.  Nice to see that the violins weren't rung up after the shaky night!
