15:53 Lockloss Due to 7.1 EQ in South Pacific
Thought there was a chance we'd ride through this one as I watched signals get bigger and bigger over 30min, but as Seismon predicted, the R-waves did us in at exactly the time Seismon predicted they would! Attached are screenshots of what I was looking at here in the Control Room. Below is a timeline.
Will wait it out with Green Arms or in the DOWN state as I wait for seismic waves/ringing to subside.
- 15:20 Received notification for "large eq"
- 15:24 Switched to EARTHQUAKE state since I saw signals fairly fast on ndscope & StripTool signals. We'll see how it rides this out.
- 15:53 Lockloss due to EQ. At this point transitioned to LARGE_EQ_NOBRSXY.

Didn't really calm down until about 17:05, but even then locking wasn't great.
In the middle of an alignment now.
