Should I Swim Out Into the Ocean Before the Sunami?

Do not attempt to swim two miles out into the ocean and then swim ba ya ah, there there. You have anywhere from five to 30 minutes to get to a safe place. So it is perfectly possible that you could walk at a leisurely pace up a hill and survive. But if you see an earthquake and you're walking along a beach, you go climb up that hill, and you do it now. The big one is overdue and is coming any day. Is that true?
