MAGNITUDE 5.1
Can damage poorly constructed buildings; well-built structures usually escape with little harm.
The scale is logarithmic: this released about 45 times the energy of a magnitude 4.0, roughly the energy of 674 tonnes of TNT.
10 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.
