    Has there ever been A 1000 feet Tsunami?
    Some paintings show huge tsunamis. But so far, I've only heard of 7 foot ones or so in my life time.

    Do tsunamis ever get near 1000 feet?

    I was originally going to respond that it would take a hugely catrastrophic event like a large asteroid impact in mid-ocean to generate a tsunami 1000 feet tall (remember the movie "Deep Impact?"), and that there is no evidence of such an event in recorded human history. But then I ran across this:

    Physics of Tsunamis

    It mentions a 500-meter tall wave in Lituya Bay, Alaska that was caused by a land slide. More info here:

    Biggest Wave

    So I defintely learned something today!
