This was a light earthquake. It is usually felt clearly nearby and can rattle windows and dishes, but damage is uncommon. 3012 people have reported feeling it to USGS.

How big was it?

This earthquake released about 60 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.4 would have released about 32 times as much.
