Lock Loss from Earthquake 1333UTC
6.5mag from Japan. Showed up much earlier than seismon predicted, and much more suddenly than I could react to.
I have switched to LARGE_EQ_NOBRSXY and so far nothing has tripped.

The EQ finally showed up on the USGS webpage at 1344 UTC
Interesting. At Livingston we were a bit farther away, so the P-wave (which did not knock us out) was reported by seismon and the S-wave (which did knock us out of lock) hit us almost exactly when seismon said it would.
