The scale is logarithmic: this released about 350 times the energy of a magnitude 3.0, roughly the energy of 169 tonnes of TNT.
46.1 KM DEEP
Shallow earthquakes release their energy close to the surface, so they are felt more strongly, and do more damage, than deeper earthquakes of the same magnitude.
