Lockloss 04:09 UTC
Lockloss due to an EQ that hit before EQ mode could activate. Seems to be either very local or very large - not on USGS yet.
The University of Oregon station "DING" saw a large signal for this earthquake, ~30 seconds before we lost lock and ~10 seconds before we saw any ground motion on site. I believe the units for the picket-fence seismometers are in [nm].
