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
