How does the distance from focus to epicenter affect the strength or magnitude of an earthquake?

Therefore, the farther a seismic recording station is from the earthquake epicenter the greater will be the difference in time of arrival between the P and S wave. ... For example, a magnitude 5 earthquake produces ten times greater ground motion than a magnitude 4 earthquake

I actually had to do a project on this in 7th grade. The vomerine teeth should be in that picture on the top of his mouth.
