Hasing no friends to call me I don't have this problem. But I often feel my desk chair oscilating like if there was a micro quake. While nothing else moves, and god knows that my collection of crap standing on weak shelves is just begging to fall at the furst cat fart...
Still find funny not to find anykind of kid science experiment earthquake meter thingamabob device for sale... (could be a kick ass USB gadget for crousourced monitoring...)
