Both can be easily countered if you put the thought into it, but I would probably say tornado. You'd get much more screwed up by big gusts of wind than being shaken around and having things fall on you. Once you're in a tornado that's it, but you can easily hide from an earthquake more than a tornado. You could always try the basement/buthtub or outrun it though.
EDIT: god damn. How did I answer a question that was several questions back? I would likely have some sort of melee weapon. You could be able to feel your own fury more than a ranged weapon.
