Tsunamis

=**Tsunamis**=
 * A tsunami is a violent disturbance deep below the oceans surface. Tsunamis are caused by earthquakes below the ocean. Huge waves are formed that surge towards shore. Tsunamis are very difficult to measure. They are usually measured according to damage but in some cases not. A chart can be used to measure a tsunami like this one below.**

Finding the speed of the tsunami can also be difficult but an equation that takes into consideration the path of the tsunami can help. How far did the tsunami travel? An easy way to figure this out is by using the equation below.
 * Intensity level || Height in meters || Description || Frequency in the Pacific region ||
 * 1 || 2 || Moderate with flooding of gently sloping coasts, slight damage. || 1 per 8 months ||
 * 2 || 4 || Large with flooding of shore, some light damage to structures. || 1 every year ||
 * 3 || 8 || Very large with general flooding and heavy damage to shoreline structures. || 1 every 3 years ||
 * 4 || 16 || Disastrous with almost complete destruction of structures. || 1 every 10 years ||

s=(square root) gd


 * speed equals the square root of acceleration due to gravity (9.81 meters per second squared) multiplyed by the depth of the ocean (meters)

Take the java trench as an example the tsunami traveled 7,725 meters

after setting up the problem according to the equation above the speed of the tsunami is 275.2 mps

A tsunami in Puerto Rico traceled at 2905 mps aswell.
