If I saw any of that shit coming, I'd prepare to die with the rest of humanity, but make sure I did so fucking stoned off my ass, with a bong raised in the air like a holy symbol, and a joint hanging out of my mouth. When the wave was like 3 seconds away I'd say "I die for the ganja" and then get wiped out. If anyone survived they'd find me dead in the water with a stoner perma-grin on my face.
