I just added it to the list of things that I've slept through. Of the natural disasters, I've slept through tornadoes, hurricanes (three of them), major thunderstorms and now an earthquake. Not mention a noisy upstairs neighbor, my ex-wife yelling at me, the noise of the ship when I was in the Coast Guard, my sister's very loud voice and many many other things. I sometimes believe that I could sleep through a Matalica concert.
