Question

give the salient features of Tsunami ​

Answer 1

Answer:

Tsunami are characterized as shallow-water waves. ... The rate at which a wave loses its energy is inversely related to its wavelength. Since a tsunami has a very large wavelength, it will lose little energy as it propagates. Thus, in very deep water, a tsunami will travel at high speeds with little loss of energy

Answer 2

Answer:

Tsunami are characterized as shallow-water waves. ... Wind-generated waves usually have period (time between two successive waves) of five to twenty seconds and a wavelength of 100 to 200 meters. A tsunami can have a period in the range of ten minutes to two hours and wavelengths greater than 500 km
