Enter the total water depth into the calculator to determine the tsunami velocity.

Tsunami Velocity Formula

The following equation is used to calculate the Tsunami Velocity.

Vt = SQRT (g*D) * 2.237
  • Where Vt is the tsunami velocity (MPH)
  • g is the acceleration due to gravity (m/s^2)
  • D is the depth of the water (m)

To calculate the tsunami velocity, take the square root of the product of the depth of the water and the acceleration due to gravity, then multiply by 2.237.

What is a Tsunami Velocity?

Definition:

Tsunami velocity describes the rate of propagation of tsunami waves through the ocean based on the depth.

How to Calculate Tsunami Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate Tsunami Velocity.

First, determine the depth of the water. In this example, the depth of the water is found to be 200m.

Finally, calculate the Tsunami Velocity using the formula above:

Vt = SQRT (g*D) * 2.237

Vt = SQRT (9.81*200) * 2.237

Vt = 99.086 MPH

FAQ

What factors can affect the velocity of a tsunami?

The velocity of a tsunami can be affected by several factors including the depth of the water, the topography of the ocean floor, and any geological obstacles it encounters. Changes in water depth as the tsunami approaches coastal areas can significantly alter its speed and energy.

Why is it important to calculate tsunami velocity?

Calculating tsunami velocity is crucial for predicting the arrival time of tsunamis at different locations and for emergency preparedness. It helps in issuing timely warnings to minimize damage and save lives by evacuating areas that are at risk.

Can tsunami velocity be used to predict the impact of a tsunami?

While tsunami velocity provides information on the speed of wave propagation, predicting the impact of a tsunami also requires understanding its amplitude, energy, and the coastal topography of the area it will hit. However, knowing the velocity can help in estimating the potential arrival times and preparing accordingly.
