This was a small earthquake. Shaking like this is often felt indoors nearby and very rarely causes damage. 36 people have reported feeling it to USGS.

How big was it?

This earthquake released about 1,900 lb of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 4.2 would have released about 32 times as much.
