This was a light earthquake. It is usually felt clearly nearby and can rattle windows and dishes, but damage is uncommon. 847 people have reported feeling it to USGS.

How big was it?

This earthquake released about 150 tons of TNT. Magnitude is logarithmic: each whole step up releases about 32 times more energy, so a magnitude 5.7 would have released about 32 times as much.

  5. Around the size people start to feel M 3.0 this one released 320× more

Energy from the Gutenberg–Richter relation (log10E = 1.5M + 4.8), rounded to two figures; bar length is magnitude, which is already a logarithm of energy. Magnitudes of past earthquakes from the USGS catalogue.
