Question

True or false

Answer 1

Answer:

That statement is true.

Explanation:

They wave that is the first one to be recorded in the seismograph is called the Compressional primary wave (or the P wave). Secondary wave is recorded last on seismography because it has slower travel speed in rock compared to the compressional primary wave.

Even though it's slower, Secondary wave tend to have larger amplitude and shaky motions. This what caused the Secondary damage to create more damage in an earthquake compared to the P wave.
