MAGNITUDE 5.4

Can damage poorly constructed buildings; well-built structures usually escape with little harm.

The scale is logarithmic: this released about 130 times the energy of a magnitude 4.0, roughly the energy of 2 thousand tonnes of TNT.

74 KM DEEP

At this depth the energy spreads before it reaches the surface. Shaking is usually weaker than a shallow earthquake of the same size, but it can be felt across a wider area.
