We were cruising along trying to align green beams to a red lock when an earthquake in Japan killed the lock. 
Interesting notes:
- There have been two EQs in the past 16 hours,
2015-02-19 13:18 UTC in Vanuatu, 6.4 M
2015-02-20 04:25 UTC in Japan, 6.3 M
- Attached is a band-limited RMS velocity of the 0.03 to 0.1 [Hz] band over the past 24 hours. This shows that, on site, the Japanese earthquake hit harder, almost 2/3rds more amplitude than the slightly stronger (at epicenter) Vanuatu quake.
- The SEI systems, HEPI and ISIs rode out the EQs without a problem. In fact, looking at the BLRMS colored performance matrices of all the ISIs, the only non-green blocks are the very lowest band, (0.03 - 0.1 [Hz]) that have gone orange (indicating the displacement is between a factor of 100-1000 larger than requirement in this frequency band). 

@DetChar -- it would be great to get ASDs and time series of lots of sensors during these two quakes and compare them against each other and "quiet" time. Note this would note just be a pull of the summary pages, 'cause I want a few averages, just around the EQ time.
(1) Check the arm length stabilization control signals: H1:ALS-[X/Y]_REFL_CTRL_OUT_DQ, roughly pre-calibrated [um] (the calibration may be off by a factor of two, and there's a minus sign between the two arms). Note that they also saturate near the limit of their range
(2) Check the GND STSs' (a) time series to *see* if they saturate, and (b) their ASDs (in displacement, preferably) to see how loud all frequency bands get. H1:ISI-GND_[ETMX,ETMY,ITMY,HAM2,HAM5]_[X,Y,Z]_DQ -- should be calibrated into 1 [nm/s] (only above ~10 [mHz], so be careful when looking at 30 [mHz] data)
(3) Check the Beam rotation sensor: H1:ISI-GND_BRS_ETMX_RY_OUT_DQ -- should be calibrated into [rad]. Good also down to ~10 [mHz]
(4) BSC ISI T240s
(5) HAM ISI GS13s
