Tsunami Characteristics | Pacific Tsunami Museum

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. Hence in very deep water, a tsunami will travel at high speeds and travel great transoceanic distances with limited energy loss.

Characteristics of a Tsunami – “The” Tsunami

Characteristics Tsunamis cause damage by two mechanisms: the smashing force of a wall of water travelling at high speed, and the destructive power of a large volume of water draining off the land and carrying a large amount of debris with it, even with waves that do not look large.

Tsunami : Causes, characteristics, Signs and the most destructive …

Characteristics of a tsunami wave The wavelength of the tsunami wave is very long, often hundreds of kilometres long (a regular wave has a wavelength of about 30-40 metres). Earthquake tremors travel at 970 km /min while tsunami waves travel 800- 900 km/hour in open waters. Its speed also depends on the depth of the water.

Tsunami – Characteristics

As the tsunami approaches the coast and the waters become shallow, wave shoaling compresses the wave and its speed decreases below 80 kilometres per hour (50 mph). Its wavelength diminishes to less than 20 kilometres (12 mi) and its amplitude grows enormously.

Tsunamis – characteristic and causes You’ll Remember | Quizlet

Many tsunamis have an effect at least 500-600 metres inland, depending upon the coastal geography When a tsunami reaches land, its characteristics will depend upon: • the height of the waves and the distance they have travelled • the length of the event (at source) • coastal physical geography, both offshore and in the coastal area.

True The height of water behind a tsunami coming ashore rapidly declines because of the short wavelength of tsunami False The maximum speed of tsunami propagation through the deep ocean basins is closet to 750 km/hour A database of 1691 models of tsunami propagation are held by this group to help forecast tsunami arrival times

PDF

A tsunami in the deep ocean has very long wavelengths and very low amplitude. Approaching the shore the tsunami will slow down in speed and amplitudes will increase dramatically. This is due to the fact that the tsunami’s energy fl ux, which is dependent on both its wave speed and wave height, remains nearly constant.

Geohazards [Tsunami Wave Characteristics]

The velocity and height of tsunami waves is controlled by the depth of water through which the tsunami is moving. The velocity of tsunami waves is calculated by: v = 3.6 (g h) where: v = velocity in m/s. g = acceleration due to gravity (9.81 m/s2), acting on the water column uplifted by the tsunamigenic earthquake. h = ocean depth.
