Effect of the Earthquake 02:12 JST 01 Feb 2020

[Aritomi, Yuhang, Eleonora]

The strong earthquake of last friday night ( https://www.jma.go.jp/en/quake/20200131171237393-01020757.html) moved INPUT pitch too much and we could not recover with local controls.

So we used picomotors. Almost all the suspensions show a jump. See attached plot. Anyway the cavity has been realigned and looks more stable than usual.
