I was awake it was a pretty good jolt but prolly magnified by all the junk, from reorganizing my room, that rattled.
My big tanks prolly didn't even budge, the water prolly had enough dampening capacity and my diy stands are pretty overbuilt solid, only worried slightly about my 60g in my room on the store bought open stand that has a slight wobble to it I may brace it now lol.
Small earthquakes release the energy otherwise being built up for a big one. If a big one hits straps won't make a lick of difference if the wall falls lol.
