a simple rule would be to bolt everything down. large cabinets for example are dangerous if they topple over so bolting it to a wall or the floor would be a good idea. also avoid having shelves or glass over your bed. during an earthquake, they may fall and break on top of the sleeping person. make rooms foot traffic-friendly. this means you can easily walk to and from doors without zig-zagging around furnitures. so when an earthquake does come, evac to a doorway or outside would be easier. hope this helps.
can you narrow it down to front or rear? it may be a bad axle or a ripped axle boot. as the wheels spin so do the axles and the boot if ripped sometimes makes a humming sound.
hide under a desk but if the building collapse. Who knows from there.
