Tsunami a threat to many Pacific Islands

While it is true that in the deep ocean a tsunami's wavelength is so broad that the wave's height is almost imperceptible, we all know that many small Pacific islands are barely above sea level, and many do not have the sheer drop-offs to the seafloor that would prevent a tsunami from slowing down and rearing up into a very perceptible and very dangerous wave. Both of these traits mean that tsunamis can be dangerous to many Pacific islands, whether the tsunami begins nearby or far away. -Dan Clem
