15 foot Tsunami

Whether it will carry at this height across the Pacific Ocean I don't know. But, just remember a tsunami is not just a wave it is a section of the whole ocean around that wave rising this much. So, for example if a fifteen foot tsunami hit Los Angeles it would be a continuous wall of water 15 feet higher than the normal ocean and might go miles inland if it could. So, this is why something like this is so dangerous to people around the Pacific Rim of the Pacific Ocean.
