East coast geology (older, harder rocks) causes earthquakes to feel about ten times stronger than a west coast earthquake. This is felt roughly the same as a 5.8 in California. That's enough to be notable, especially at a shallow depth.
> 4.7 is literally nothing
4.7 quake at 1 km depth will shake more at the surface than a 6.0 at 30 km depth
4.7 at 5km depth is still nothing for anyone not immediately above the epicenter.
