I checked TM actuators of ETMY.
All actuators seems not working (fig1-4).
Also, I checked if each actuator can excite the resonance (fig5), but no actuator can excite the resonances.

I took some Tcam pictures of ETMY.

One magnet-like object can be seen.

One pre-earthquake photo is attached for reference, but we can not see any magnet-like objects other than the right one.
