After jetheral pointed out this article to me but before I even read it, I realized that earthquakes can be devastating to telescopes - and perhaps the world's best observatory is at Mauna Kea. To start off, I can't really picture telescopes being mounted on shocks or something b/c the pier's supposed to be directly into bedrock so no building vibrations mess with the image. Add to that, that if the location of the telescope (or the whole island) shifts in an earthquake, something will need to be fixed to account for that.
And in fact, I'm right on that last one - one of the tele's shifted by as much as an inch, and they're going to have to recalibrate a crap. Thankfully no mounts or optics were damaged, my collaborator tells me that there actually were some stabilizing equipment on Keck 2 that probably saved it, only things like encoders (tell position), breaks, and the location calibration. I'm curious as to how long that'll all take to fix, b/c those telescopes with damage are useless until that happens.
Ooh, and I know major telescopes are insured by Swiss banks or whatever, I wonder if they get to collect here.
ETA: The CFRT is back online! The Kecks are not (as of Fri Oct 19).
