Terramon has just come up with a RED warning of a 5.6 Peruvian earthquake who's Rayleigh wave is due here in a minute (0.7um/s), due at 15:30:38UTC.  We'll see what happens.

L1 just went down at 15:30.  Terramon said the EQ's Rayleigh waves (of 1.4um/s) would arrive there at 15:17UTC.  

So we might not be out of the woods yet...watching 0.03-0.1Hz (all three axis have yet to move up at the same time and all are still under 0.1um/s...I've seen us drop out when all three go above that velocity...but that was a few weeks ago before the DHARD filter).  

No signs of anything on tidal or ASC control strip tools either.

It's been 15min since the R-wave arrival estimate, I'm assuming we rode through the EQ.  (it was barely observable in here on seismic bands, range, striptools).  Time to make breakfast/coffee.
