The 5.8-magnitude quake that occurred in Virginia was felt up and down the Eastern United States and even in Canada. In contrast, a similar magnitude earthquake on the West Coast would be felt more locally. Geologists say this difference is due to the earth’s crust. The crust in the West Coast is less dense and contains more active fault lines while the East Coast is denser and contains less fault lines. This means the same earthquake will travel further from the epicenter.
