Lock Loss mag 6.2 in Canada 
   Lost lock due to a mag 6.2 earthquake near Port Hardy, CA. There was no warning from any of the EQ systems until after the quake hit. All ISI and several HEPI platforms tripped. Primary microseism is off the top of the chart. 

  Will try resetting the platforms, but do not hold out much hope for relocking anytime soon.

   At 03:38 (19:38) lost lock. One minute later the all the ISI, several HEPI, and suspensions started tripping. At 03:42 (19:41) got a verbal alarm of a large earthquake in nearby Canada. Put the SEI_CONF into LARGE_EARTHQUAKE and started to reset the suspensions, ISIs, and HEPIs. The Peak Non NDScope topped out at 152,000um/s. It has since dropped down to around 6000um/s. 

   Will monitor until things settle down and try to relock. The BS looks way off, so anticipating an Initial Alignment before getting the IFO back up. LLO is down as well.
