Coastal tsunami waves with wavelengths, which can be noticed from the coastal waves usually have about 1 meter or spectrum does not exceed 10 m, but for long-term tsunami 100 kilometers or more wavelengths of about 100 kilometers.
coastal waves and tsunami waves observed by the waves, which normally has a range of about one meter, or up to 10 meters, but for tsunami wave length range of approximately 100 kilometers or 100 kilometers.
Coastal waves with observations from the tsunami wave, which normally has the coast waves wave around 1 meters or more than 10 meters, but for the tsunami wave phase range about 100 kilometers or more 100 kilometers.
