The coastal waves with wavelengths that Tsunamis are different. By coastal waves normally have a range of approximately 1 m, or up to 10 m, but for long-term tsunami 100 kilometers or more wavelengths of about 100 kilometers.
Tsunamis are waves with different wavelengths. The normal waves with wavelengths of around one meter, or up to 10 meters, but for tsunami wave length range of approximately 100 kilometers or 100 kilometers.
With the wave Tsunamis coast waves are different. The coast has the normal wave wave around 1 meters or more than 10 meters, but for the tsunami while the waves about 100 kilometers or more 100 kilometers.
