Also, be sure to have a video camera on hand. Now that you're fully prepared, we may as well have an earthquake. Run around and scream as though your vital organs were being violently removed. This is important, as it makes the news footage look good. Drive your car into what's left of the lake.
Nothing is more boring than an earthquake where no one is hurt and no damage is done.
I take that back. If you get the urge to protect yourself, try holding household pets over your head. Almost anything will do, but large dogs work the best. Of course, it will be obvious that an earthquake has occurred because any old people who may be present will be laying on the floor, mumbling incoherently to their dead spouses. But you must ask the question anyway.
