\nAs Tsunami waves approach the coast, the water depth decreases.
\n<\/section>\n
\nTsunami waves are long-period waves. As they move from the deep ocean into shallower coastal waters, their speed decreases due to friction with the seabed, but their height increases significantly due to the conservation of energy. This phenomenon is known as shoaling.
\n<\/section>\n
\nIn the deep ocean, tsunamis have a long wavelength and small amplitude (height), making them often unnoticed by ships. As they enter shallow water, the wavelength shortens, the speed slows dramatically, and the wave height can build up to several meters or even tens of meters upon reaching the coast.
