Say between Hawaii & French Polonesia. What would it look like standing on the beach in LA or Sydney? Can anyone give detailed description? Like would the sky out on the ocean front light up like a second sun? What kind of a wave? How far inland would it reach? Would it be followed by tremendous blast front of material rocks etc? If the material reached that far. In terms of material being launched into the atmosphere, would the impact be much less then if impacted on land? Would you feel the earth shake a bit on the far side of the planet? All of got to go on is Hollywood films.
