We told you about why more earthquakes are felt on the East Coast as opposed to the West Coast due to smoother, older rocks, able to carry vibrations to further extents. There's also the obvious reason being more population and more vulnerable infrastructure. But the largest earthquakes in the US happen on the West Coast for a reason.

Here is where tectonic plates are rubbing together. You've likely heard of the San Andreas Fault line. This is where the North American Plate and the Ocean Plates are moving in opposite directions. This force creates vibrations, and therefore pressure. On the East Coast, there are no tectonic plates moving against each other, which is a good thing.

In fact, because there are more tectonic plates over the Pacific Ocean, this area is called the 'Ring of Fire' by seismologists. This area surrounding the Pacific Ocean from Peru to Alaska to Japan is where the largest earthquakes in the world occur, and it's because of all the vibrations and movement. 

Because lesser-strength earthquakes occur in the eastern US, less is known. But what we do know, is having weaker earthquakes is not a precursor for stronger earthquakes. It's the opposite. These weak earthquakes are a good thing as it relieves pressure in Earth's crust that would otherwise be building.
