This was a fast earthquake with SEI_ENV going to EARTHQUAKE mode being the first heads-up about it, with Tidal signals(nuc28) and Picket Fences showing seismic motion a few seconds after.....with H1 losing lock at 936utc (L1 dropped out 932utc).
IMC could not lock for the first 7min-post lockloss due to seismic motion. Once it locked, will hold at LOCKING ARMS GREEN for 30min & then asses seismic situation for locking.
It's been 12min and the USGS site still has not posted this Earthquake (I found it via other fast websites), but as I typed Verbal noted "incoming earthquake from Guatamala).
Almost back....doing the usual violin waiting dance at OMC Whitening....I think it's time for lunch though....I'll come back to check on things, since it'll take a while here.
