If a meteorite 1/4 mile across struck in the Atlantic Ocean, how high would the tidal wave it produced be?
The impact and the resulting damage would depend on the meteorite’s size, material composition, speed, and impact angle. The 1998 earthquake-induced tsunami in Papua New Guinea that wiped out coastal villages and killed thousands of people was only a few yards high. If a meteorite hit the Atlantic, we could easily see a tsunami wave 100 times higher. A 300-foot tsunami, for instance, would cause great damage to low lying areas all along the U.S. east coast, and could totally submerge vast areas in Europe, such as Holland and Denmark. A 300-foot tsunami could travel inland on the U.S. east coast about 14 miles.
