MAGNITUDE 5.6

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

The scale is logarithmic: this released about 250 times the energy of a magnitude 4.0, roughly the energy of 4 thousand tonnes of TNT.

4.5 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.

NEARBY IN THE PAST 30 DAYS

1 earthquake above our reporting threshold within 250 km of this one, the largest a magnitude 4.2.
