Although we do not get serious* earthquakes here in the UK, it seems to me that a very useful prep could be to place important belongings in a small lightweight cloth bag that is hung up near the bed where you can easily reach it.
Contents could include, glasses, cellphone, keys, wallet, flashlight.

If these items are placed on a shelf or table as is more usual, then an earthquake could throw them to the floor where they would not be readily located.

A small cloth bag on a hook, would still be hanging on the hook and be instantly located. A beta light in the bag or next to the hook would assist in locating it.

Shoes are a bit bulky and heavy for this, but could perhaps be hung from the laces next to the bed, or perhaps from the side of the bed.

*We have recently had an earthquake that was strong by UK standards, I was a bit startled by it because I was using the toilet at the time !
Many did not even notice it, and that was the most severe for 10 years.
