I originally thought this lockloss was from a M5.4 EQ from Chile that was predicted to hit at this time, but now that the USGS site has updated and looking at how sudden and hard-hitting the lockloss was, I now suspect this was from a M3.2 EQ from Desert Aire, WA, a mere 20 miles northwest of the site.

Since this quake was so close, ground motion calmed down quickly and I've started the relocking process.
